AB: Clearly split. A definitely brighter than B. Under a NELM 5m5 sky both components appear weak in these mini-binoculars and no colour impression arises.; WZ Cas is the variable designation of component A of STTA254. This semiregular carbon star has a mean brightness range of 6m8 to 7m7, and can reach extreme values of 6m3 at one end and 8m8 at the other. Perhaps it was too deep in a minimum at the time of observation to show colour with 1 inch of aperture? 15x45 binoculars revealed colour in this night, see observation below. |

Light orange stars, split with 333x. WDS calls it physical and even provides an orbit with a 649-year period, but they do not share parallax ranges (-54%), in spite of a very close 154 AU weighted separation, 1.63/1.15 Msol, the radial velocity delta (15.51) greatly exceeds the escape velocity (6.18) -- so these are not gravitational |

Per EDR3, AB has 44% shared parallax ranges, but a very wide 16,943 AU weighted separation, 3.12/2.75 solar mass, so time will need to tell. I do not find data on C. I did not notice AC the Burnham pair, which has a low catalog number indicating 6-inch era discovery, but the year is 1889 which puts it at the Lick 36-inch, discovery separation 0.4" |

V547 Cas. Faint, very fine pair, seen at 205x and had a better look at 333x. Wide, ~4" slightly reddish faint stars. SkyTools brought this up as a short period pair, however it won't make a significant change in my time. It turns out A is also a pair, MCY 1 Aa-Ab, 10.8/12.5 0.5" with a period of only 15.59 years -- discovered by one D.W. McCarthy (no relation!) in 1989 during the first results of the Steward Observatory Infrared Speckle Camera using their 2.3 meter telescope. The Ab star has a mass of only 0.18 of the sun. I think it is gettable visually with the Challenger on a good transparent night, or with the Lick Great Refractor if I ever have the good fortune to observe with it |

Despite the wide separation the pair holds together visually very strongly, and dominates the FOV. And indeed, Stelledoppie states it is a true physical pair at 174 light years from us. Component A is ice-blue. I probably wouldn't have any strong colour impression coming across component B on its own, but standing next to A it seems a washed-out orange. |

Very faint wide B needs foveal coaxing and then can hold direct. WDS claims physical, however they don't share parallax ranges (-15%) and there's a quite far 4,521 AU weighted separation 2.62/1.13 Msol, so they likely are not binary |

The group of stars strikes the eye while sweeping from Mirach to Tau/Upsilon TRI. First thought I'd found an open cluster. Two pairs with practically opposite PAs. Southern pair AB much closer than northern CD, but brightnesses within the pairs very similar. A nice double-double. |

The components A-D and F easily visible as a rather conspicuous group with comparatively large distances. I didn't pay attention to the component E. No brighter stars in the immediate vicinity. The pair AB and CD are very similar; CD a bit wider with opposite position angle. Very nice multiple star also for smaller telescopes. |

On tripod. Wide split. A orange-red, B a tiny pinprick of light. Attractive sight in 7.3° field of view, with Zeta Psc neatly on western edge of FOV. Physical double according to Stelledoppie. Three-star rating awarded because this is a physical double that can be resolved at 7x, while dominating the field of view with more power and presenting a strong colour contrast with more aperture (see 20x80 observation below). As an added bonus, S398 is just half a degree south of the ecliptic and is thus visited regularly by planets and the moon. |

In brief moments definitely split with a hair's breadth of black in-between. The rest of the time tantalisingly close to popping apart. Brightness difference distinct enough at all times to identify the southern star as the A component. Both components pure white.\A physical pair 164 light years distant from us. Also known in ancient times as the "First Star in Aries", as it was closest then to the vernal equinoctial point on the ecliptic |

It is now (1898) a very difficult object, and only measurable with a large aperture under the best conditions." 1.0" at discovery, it is now 0.4" and found to have a 61.14-year period and will continue to tighten until the 2040s.

Fine split. A is mandarine orange. BC has trouble displaying its colour due to the overpowering light of A, but in good moments is clearly blue. A-BC is a physical double at a distance to us of 393 light years. BC is also physical, with a relatively short period of 63 years for C to circle B and a very tight periastron. Unobservable in 2013 at periastron with 0.1". Since then the angular separation has been widening rapidly and will reach 0.4" in 2029. B-C will then become observable in large amateur telescopes for three decades, after which C will fall quickly back to B. |

BC: Component of STF 205, of which A is a brilliant orange and BC bright blue. In BC I can only see elongation through the speckle at 667x and 1067x. Short 62.63 year period which will get "easier" to about 0.2" by 2045 |

Mark McCarthy

508mm (1067x) |
BC: I spent a good long while on this one, and tried hard to nail down the position angle. At 1067x, both with and without an apodising mask, but both times with a #80A light blue filter, which did seem to calm the diffraction a little, I had a clear view of the elongation with a strong sense of the weaker end being to the East or to the ESE. I also tried a 78% central obstruction mask, and while the diffraction became a grid, and the disks much smaller, I could clearly see the same elongation and weaker end, though at a much smaller scale. To my delight the current orbital solution puts the PA at 120.6-degrees, 0.179" separation, so I think I have detected it. I can't wait until 2033 when this becomes an easy pair! |

|
Christopher Hay
Seeheim (Germany) |
15x45 |
Binoculars with internal stabilisation, handheld. C far distant from A. Due to this distance and the major delta-mag the two stars do not present the appearance of a double, C looks rather like a field star. Yet in fact the two are a true physical double at a distance to us of 289 light years. |
|
Christopher Hay
Seeheim (Germany) |
71mm (13x) |
A-C wide split, C a fine little point of light. Visually un-exciting as such, the attraction of this pair resides partly in contemplating that it is a true physical double. Furthermore, in this small refractor 14 Arietis AC can be observed together with another physical double in the 5.5° FOV, namely Lambda Arietis (listed here as H5 12). |

Components A, B and C from a wide grouping. B is very faint, somewhere around 11m to 12m, in contrast to the 8m0 stated by Stelledoppie. Observed on 12 February 2021. Is B variable? DSS sky survey shows the same delta-mags that I saw, so it rather appears that Stelledoppie has a mistake in its database. A is creamy white, C grey, B too faint for any definite colour impression. According to Stelledoppie a physical triple system at a distance to us of 289 light years. |

While pleasant with 30x80, the pair becomes suprisingly difficult to split with 20x80, presumably due to the cumulative effect of 2m delta-mag and the red colour of the companion, which makes it stand out less than if it were blue (colour not seen, but stressed by Uwe Pilz in his 105mm observation, see below). |

AB: der Doppelstern steht innerhalb einer sehenswerten Formation aus 6 Sternen, die ein gleichseitiges Dreieck bilden - die hellsten drei Sterne bilde eine Seite im Norden, zur Spitze nach Süden werden die Sterne immer schwächer - STF270 steht mitten in der Nordseite - Komponente B ist wie ein kleiner zarter Hauch nordwestlich von A erkennbar, Helligkeitsunterschied mehr als 2.5 Größenklassen - kein reizvoller Fernglas-Doppelstern, aber die Umgebung ist interessant |

B well set off from A. Glare from A is an issue, consciously trying to ignore A helps. Very slight yellowish tone of A. Seeing the difficulty makes it clear why attempts in other nights to split the pair with 25x80 binoculars failed. |

Well split. Main star yellow-orange, secondary an ice-blue pinprick. With overall brightness of 5m1 just visible to naked eye under my suburban sky. Interesting star field with a line of 5 stars pointing S-SW away from 15 Tri and a further striking star chain to the west. Placing Gamma-Delta-7 Tri within 7.5° FOV makes a very attractive overall field. Mira variable R Tri just ½ degree to the S-SE was around maximum at time of observation and presented a much paler orange than 15 Tri A. Charming colour contrast ensemble with the two components of the double plus the variable. |

STF307 (AB): Miram, die Komponente A ist satt gelb und bildet ein flaches Dreieck mit zwei Sternen westlich und nordwestlich, die 1,8' und 3,9' entfernt stehen - dazwischen wird alles vom Glanz von Miram überstrahlt - im Fernglas hat B mit den eigentlich ordentlichen Daten wie Abstand 30,4" und Helligkeit 8.5 mag (andere Quellen sagen 10.7 mag) trotzdem keine Chance auf Erleuchtung |

508mm (1067x) |
AB: I suspected elongation at 667x and it was better seen at 1067x. I estimated the PA on an E-W line, though it was tough to tell which was B. This is a component of STF 318. It is currently at apastron and won't make a significant change in the coming years. 31.63 year period. Discovered with the Dearborn 18.5-inch, Burnham says: "It is at all times a difficult pair, and the motion is rapid. It is now known to be one of the most interesting binaries in the heavens. The distance never much exceeds 0.2", so that it is always a difficult pair, and beyond the reach of most telescopes." |

Component of STF 366. Faint, and is mostly a hazy elongation which brightens each end with seeing --- difficult on such a night as this with poor seeing and transparency. It makes me wonder how Struve missed it? There are 26 observations in WDS so it should have been determined to be physical by now |

Well separated but very strongly appearing to belong together. This impression is fostered by the almost identical brightnesses and the complete lack of visual competition in 0.6° FOV. Leading star appears at first sight more orange than the other, but after a while this shifts to the other star. The pair is visually very attractive at this power, and a true physical one at 670 light years distance from us. |

in diesem FG ein schönes enges (knapp getrenntes) Paar - B steht südwestlich - weil beide Sterne so eng stehen, ist der Helligkeitsunterschied schwer abschätzbar, ich denke 1 bis 1.5 Größenklassen |

No definite elongation of AB seen at 110x, seeing is poor. But nice pinprick of light wide off to NE, seems bluish, this is the C component. AB-C is physical at 429 light years distance from us, and so is A-B, so this is a physical triple system. Very easy to find 3° due west of the Pleiades. |

Excellent! Near equal light yellow-orange stars, hairline at 175x and close clean split at 285x. Burnham discovered with the 18.5-inch Dearborn refractor at 0.4". WDS has medium confidence of binarity with a 463-year period, currently coming off apastron. However there is no shared parallax range (-12%), despite only 103 AU weighted separation and 1.63/1.68 Msol. This may turn out not to be binary |

On tripod. Well separated. A evidently brighter than B. A appears to tend towards orange, B rather towards blue. Most of the Alpha-Persei cluster can be viewed together with S430 in 7.2° FOV. Seen thus, S430 feels likes a distant little echo of the powerfully orange-blue pair Sigma Per in the cluster. South 430 is a physical double at a distance to us of 498 light years. |

2025-02-03: S437 AB-C at 30x conspicuous and easy. Component C shines orange and is slightly brighter than the white-bluish component AB. With BU536 AB, the companion is indicated at 171x, barely visible at 240x and clearly visible at 300x. It lies close to the first diffraction ring of A and appears much fainter than the difference in brightness would suggest. Under less good conditions, the companion blurs quickly and is difficult to see. |

BU 536 AB: 16 January 2025. Burnham 536 AB is harder to split than the data would suggest. After many failed attempts over several years with six and seven inches of aperture, at last success with eight inches at 230x. Stable, distinct split with substantial delta-mag. Physical pair with separation at time of observation of 1.07 arc-seconds according to Stelledoppie. Slowly widening, was 0.91 in 2000 and will be 1.18 in 2050. Nice slightly orange hue of C component in South 437 AB-C, of which GU 536 AB is the AB element, still evident even at this small exit pupil. S 437 AB-C is not physical. |

BU536 (AB): Wow what a great pair. B is a clean split ~1" right next to A, approximately 1 delta. More amazing to see than I can describe. Aitken had a measure of 0.15" in 1899.70. Burnham discovered with the 18.5-inch at 0.4" and notes "It is important that the close pair should be watched and measured in the near future." Physical, 885.64 year period, now widening |

I see the slightest bump on side of A, very much fainter. I disabled tracking to record my impression of the position angle, which I had to the ESE, and find this is correct. Visible only with apodising mask and with seeing. WDS is uncertain whether it is binary, but there are only 6 observations. In the Pleiades, Burnham discovered with the 36-inch at 0.3" and described it as a "difficult pair." |

Notched snowman, B is a little bluish to white A, can tell orientation, short period with PA to the SW. 61.2-year period, it will soon be at apastron. Given it's nearly edge-on orbit, I won't see significant change, except for a slightly better split, in my time |

Mark McCarthy

For this one I used an 8-inch mask on my 20-inch telescope, since the star brightness washed out the image in full aperture. It appeared as a very tight pair, hairline split, and around 1 delta mag. I estimated the PA to the south. Approaching apastron, and won't make significant change in my lifetime in spite of the 61.2-year period |

A ist gelblich. B fiel sofort ins Auge, auch bei 144x. C war extrem schwierig. A musste außerhalb des Gesichtsfeldes stehen, aber auch dann war er nur indirekt sichtbar. Dann aber überraschte der verhältnismäßig große Abstand B-C. ~ A ist ein Hauptreihenstern ähnlich der Sonne. B ist ein weißer Zwerg, einer der hellsten am Himmel. C ist ein Roter Zwerg, davon gibt es nicht viele in der Reichweite kleiner Instrumente. Insgesamt hat man drei Zwergsterne auf einen Blick: Einen gewöhnlichen (=Hauptreihen-) Zwerg, einen weißen und einen roten. |

Nearly in between is a near equal faint pair of 10th magnitude stars, approximately 6" separated, with a PA slightly off-kilter to the AB pair. The A star is an Aa-Ab pair, OCC 327, equal magnitudes but no separation given, from the Occulting Doubles Catalog -- I wonder if it would show out of round visually with aperture & high magnification |

5 Nov. 2022. In good transparency I notice while casually looking naked-eye at the Hyades that Theta1/2 Tau seem elongated. Looking now with direct concentration, the pair moves clearly apart. Theta2 is visibly slightly brighter than Theta1, PA estimated at 350°. Following this up directly by looking at Mizar/Alcor in Uma, that pair, which I can always split naked-eye reasonably well if transparency allows, now seems super-wide compared to Theta1/2 Tau. I estimate the separation of Mizar/Alcor as being two-and-a-half times that of Theta1/2 Tau. |

Theta Tauri. Luminous orange and blue. Wide apart but very much feeling to belong together, despite the many stars of the Hyades all around. A physical pair. The data suggest separation with naked eye is possible, something to try in good health under a steady sky. At all events with naked eye Theta Tauri is at the centre of the southern stroke of the Hyades' distinctive "V" shape. In the binoculars, by ignoring Aldebaran, which is not a cluster member but a foreground star, it suddenly becomes apparent that Theta Tauri is in fact at the centre of the Hyades in our sky and is its lucida. This impression is supported very nicely by 7x and 8.6° FOV. Definitely one of the finest doubles for this class of binocular. |

Used 533x & 667x. I could detect elongation at 533x, and significant notching with 667x, enough to tell which was A & B and the position angle, which I put at nearly E-W (B is tightly WSW currently). Physical with a 40.752-year period, it is widening and reaches apastron in 2029, so maybe I'll get a clean split and a more accurate PA estimate at that time |

Light yellow A and light orange B, well separated when seeing stills and the stars form airy disks, short period pair with a 97.7 year period. This will continue increasing to apastron in 2030 and beyond, though the PA will remain about the same -- I think in the future it will be splittable in lower magnifications, which is how I would notice any change. Burnham writes: "This pair was discovered with the 18.5-inch, but in looking over the old observing books used with the 6-inch, I find that on December 14, 1874, this star was noted as 'possibly a close pair'…There seems to be something singular about the appearance and difficulty of this pair at times with larger apertures. It was not noted as difficult at the time of the observation in 1877. in 1890 it was a hard star with the 36-inch and on two nights in 1892, under favorable conditions, I failed to see it double at all." |

STF747 (AB): Clearly split, with very distinct magnitude difference between A and B components. Hand tremor prevents detection of colour contrast, if there is one at all. A very pleasing tip to Orion’s Sword. A true physical pair according to Stelledoppie. Distance to us of 1610 light years could indicate membership of stellar association Orion OB1 and thus physical relationship to Orion nebula complex. |

CLL22 (AC): Comellas (CLL) 22 is the C component of STF 747 AB. C is a fine pinprick of light, a little less than twice as far from A as B is. Knowing that this is a physical triple system makes a big difference in perceiving it as such at the eyepiece. |

13x: CD definitely split, A uncertain, B not present. 18x: A, C and D definite, B uncertain. 32x: A, B, C and D present and clear. Mediocre seeing but good transparency with strong M42 and an inkling of M43 at 32x. B is an eclipsing variable with a period of 6.5 days and an amplitude of 0.6mag, presumably obervation was at minimum, which would explain the difficulty in seeing it at lowest powers. C is the main source of excitation of the great Orion Nebula M42/43. |

Suprisingly more difficult than STF572 about 15° to the northwest, although the numbers are very similar and the two systems are standing at identical elevation above horizon. At 40x STF742 is no longer definitely split, but M1 half a degree to the west is strong in 2° FOV by way of compensation. |

Binoculars with internal stabilisation, handheld. AB-D: No split, nor any elongation of AB towards D seen. AB-E: E is set off well from AB but harder to split than the numbers would suggest. This is partly due to the major delta-mag, and partly to the circumstance that D effectively reduces the "free" stretch of sky to 29". STF761 is a nice complement a few minutes of arc to the west and makes the visual impression of possibly belonging to the Sigma Ori complex, but Stelledoppie doesn't confirm this. |

Binoculars with internal stabilisation, handheld. AB-D: No split acheived. However, focussing on AB feels uncertain, presumably due to disturbance by D. Also not split with 15x60 on tripod. AB-E: E is set off well from AB. |

AB-C: bei 64x zeigt sich Komponente C ganz schwach südwestlich von AB AB-D: bei 32x schließt sich an die zartgelbe Komponente AB unmittelbar im Osten dicht stehend D weißorange an - ein schickes Trio zusammen mit E weiter östlich AB-E: bei 32x zeigt sich in vierfacher Entfernung von AB-D die Komponente E weiter östlich in einer Linie - E ist ähnlich hell wie D |

Christopher Hay

7x45 |
On tripod. Clearly separated. Large delta-mag plus scintillation of primary prevent colour perception of B. The 6x30 binoculars show the colour better in the same night. Interesting to note that the 7x45 is at a disadvantage in this regard while the 10x56, however, is superior. |

Christopher Hay

10x56 |
On tripod. Widely separated. Rather charming. B distinctly blue. Scintillation plus atmospheric dispersion of A (15° above horizon) prevent determination of any particular hue of A. A physical double at a distance to us of only 29 light years, which means Gamma Leporis is in our immediate galactic neighbourhood. |

Wow! very fine, near equal faint pair, nicely split. I'm really surprised it wasn't discovered before since any one of the greats could have seen it -- I wonder if it is a physical binary and was at periastron 75-150 years ago, and only now coming to view? |

At 57x nothing seen at first sight. At 133x the much fainter component was visible after a short time as a tiny star in the correct position angle. With this knowledge, the observation at 57x was also successful, even if one has to look very closely. The challenge here is not so much the angular distance as the large difference in brightness. |

AB: When idly viewing NGC 2169, the “37 Cluster” or “IC37”, I noticed that the brightest star in the 37, namely the one at the NW corner of the 3, is a nicely split double with a thin slice of darkness between the components. PA matches the top bar of the figure-3 well. Stelledoppie lists components of STF848 from A to K, but notes that all are either not physical or uncertain. To my eye only the A-B pair appears double-like. |

mit etwas Konzentration sind beide Sterne getrennt zu erkennen - A und B sind halb so weit voneinander entfernt wie das nahe liegende Pärchen STTA74 - Komponente B im SW ist genauso schwach wie B bei STTA74, aber dadurch, dass er näher zum Hauptstern steht, ist er schwächer sichtbar |

At 22x, the components A, B and CD are immediately conspicuous, where A dominates. They form a beautiful, acute-angled triangle. At 69x, color differences are also visible. A: subtle orange; B: grey-bluish; CD: tendency to orange. Rewarding, because the double stars STF 928 & STF 929 as well as the very conspicuous carbon star UU Aur are in close proximity and can partly be observed together in one field of view! |

Nice light orange stars, hairline split with indifferent seeing, PA to the SW. Slight magnitude difference. Physical with 102.3-year period, I have the PA reversed in my estimate, it's to the NE -- still can claim it though. It is coming off apastron and will close slightly in the next 20 years. Aiken discovered in 1900 with the Lick 36-inch also at 0.4" -- 118 years since, so it has made a little more than one revolution |

2020-03-23: At 22x, the wide pair A-BC already appears separated, but still very tight. At 69x, A appears in a subtle orange. The pair BC shows elongated and rather greenish-bluish. At 100x BC is already visible as figure '8' and almost separated, at 129x clearly separated. Components B and C are still very close together and equally bright. The color impression remains. An interesting and rewarding triple system! |

Handheld. Widely split matched pair. Easy to find half a degree south of 45 Gem. Comfortably viewed in 8.6° FOV together with STTA 80 AB and STF 1007, all three systems well-to-wide split, a charming trio of doubles. Alternatively, ENG 28 can also be viewed together with Zeta Gem (Mekbuda) 5° to the north. Engelmann 28 is a physical double at a distance to us of 152 light years. There is an interesting quirk about the ENG designation, on which Stelledoppie notes: Some time after publication of the IDS, the designation for Engelmann was changed from EN to ENG and that for Engelhardt from ENG to ENH. This has led to considerable confusion between the two. |

STTA83 (AC): Wide pair, relatively bright, moderate difference in brightness. A: slightly orange; C: grey-blue. Southeast of the pair in a much larger distance there is another, fainter star, which appears orange, partly reddish. It does not belong to the system. All three stars form a beautiful right-angled triangle. |

AE: Component E is a fine pinprick of light. The distance to A is so substantial that the pair would not normally be felt to be a double. This makes it all the more interesting to contemplate that this is a true physical double in our galactic neighbourhood at 59 light years distance to us. ALC = Allen, C., published in 2000. |

AB: 13 May 2022 (5.5" angular distance according to database). Moon four-fifths full a few degrees north of Spica in Virgo. 70mm binoculars stopped down to 42mm aperture. Directly after looking the Moon I was able to split Castor AB definitely. Could hold this for a full minute, only then did the split start to become uncertain. Repeated the observation several times, found the split to be definite each time. |

Christopher Hay
Seeheim (Germany) |
32x70 |
AB: 13 March 2022 (5.5" angular distance according to database): Moon only 6° away and two-thirds full in the middle of Gemini. After concentrated observation of the Moon I slewed quickly to Castor to exploit the heightened acuity provided by viewing the bright Moon. Castor clearly split with fine black between A and B. After a while the split became more difficult but could still be held. Followed this up with the same eyepiece previously used in the achromatic 70/400 binoculars now placed in 71/400 fluorite apochromatic telescope, thus again yielding 32x. Again A and B split after observation of the Moon, but harder to hold with the mono apochromat than with the bino achromat. |
|
Christopher Hay
Seeheim (Germany) |
36mm (33x) |
AB: 16 April 2022 (5.5" angular distance according to database): With Käsemann (KSM) polarising filter at 33x two kissing Airy disks which seem to move apart in good moments, but this is uncertain. Without filter at 33x just a squat figure-8 far removed from separation. With polarising filter at 40x definite separation, fine first diffraction ring of component A. Without filter a stretched figure-8 with no separation. At 50x clear and stable separation with and without filter. Best view at 66x, a ghostly pair in pitch-black FOV, the first diffraction rings of A and B merging, that of B very faint. With a Baader Neodymium filter the positive effects are similar to those of the KSM polarising filter, but the clarity of separation is not quite as great as with the polarising filter. |

AB: Experiment to determine the smallest magnification to separate Castor. I observed on 2022-05-09, 2022-05-11 & 2022-05-18. At 26x and 30x easily seen as a double star, but not clearly separable due to outshining. At 70x of course easily separated. Stopped down to 30mm aperture, Castor appeared partially separated at 26x, but very barely. The right viewing position at the eyepiece was important. At 30x with 30mm aperture, Castor was cleanly separated, but extremely tight. Following a hint from Christopher Hay, I also used a red filter from Baader to avoid outshining at full aperture. Now also a separation at 26x was possible, whereby the components were extremely close to each other. For me a magnification of 26x seems to be the minimum to separate Castor cleanly, if the brightness of the components is reduced sufficiently. |

Observation from the city at half moon. At magnifications between 187x and 280x I could see the very dim companion almost permanently near the first diffraction ring. But the diffraction ring itself was hardly visible. Main problem here was probably the low brightness of the companion. |

Very tough for a Struve. B is very faint and comes to view only with seeing as a very fine point, pretty well separated from A, but A needs to be a disk for B to resolve out of the diffraction. Seen fleetingly, somewhat better with averted vision but averted vision often misses moments of best seeing. Physical |

Hair-fine, but definite and constantly held split. Charming in 3.3° FOV with Phi1 and Chi Cnc. Easier than I would have thought at only 25x. This is clearly aided by the very well-matched brightnesses of the components. The 70% full moon nearby in Leo also helps, as its brightness boosts the eyes' acuity. During the observation I gaze intentionally directly into the moon at intervals in order to utilise this effect, a technique honed in earlier binocular observations of planets. Primary is slightly brighter than the secondary, again surprising considering that delta-mag is only 0m05 (6m16 to 6m21 according to Stelledoppie). Not a physical pair, alas, although it looks so much like one. |

All members A, B, C and D clearly seen and widely separated. A compact group at the northern fringe of M 44 (Praesepe, the Beehive). Component A seems orangish. Engelmann 37ABCD is a physical group at a distance to us of 608 light years. Stelledoppie notes about the ENG designation: Some time after publication of the IDS, the designation for Engelmann was changed from EN to ENG and that for Engelhardt from ENG to ENH. This has led to considerable confusion between the two. |

Tight white stars, seeing is not very good but can still split it. It has a noticable magnitude difference, however I need to guess which one is A. I am able to estimate PA by drifting it across the field. [My PA is in the correct line but my A and B are reversed.] 70.89-year period, it is now at apastron and will make a very small turn in its arc by 2040 |

Clearly split, a little tighter and much less striking than nearby STF 1311 (two degrees to NSW). STF 1332, at a distance to us 233 light years, has the benefit of a documented orbit, while STF 1311, 190 light years distant, is a common proper motion pair. Hence two physical pairs reasonably close both in the plane of our sky and in actual space. |

AB: 2020-04-24: Seeing was mediocre (3/5). The faint companion was partly seen as a distinct brightening in the first diffraction ring of the primary component. Not at all easy. Steady air necessary. |

AB: Very tough, B is a very tiny point or fleck very closely split, need low power to reduce flaring from bright light yellow-orange A. Burnham discovered with his 6-inch and says: "A fine pair even with a small aperture." |

AB: Kappa Leonis: Very tough but palpable split. Seeing needed to settle to perfection for primary to resolve to just an airy disk without diffraction or flaring, and for a couple of seconds could see the much fainter ~10th magnitude B star as a pin-point, ~2" separation. Fleeting view. |

At 69x and 100x, the pair AB shows a nice color contrast: The eastern component mostly appeared in a slightly shiny orange, while the other component appeared more white-bluish. During the observation, however, the colors changed between both components. At the time of observation, the pretty bright comet C/2019 Y4 Atlas was also in the same field of view - a great scene!

Emboldened by the unexpected ease with which the pair can be seen in the 10x56, I launch an attempt with 7x50 bins on the tripod. This is thwarted by the many rays emanating from A in the image. Too much exit pupil? AB is a physical double at a distance to us of only 79 light years. |

AB: bei 49-fach ein sehr weites, ungleiches Paar, gerade noch so als Doppelstern wahrnehmbar, Komponente A strahlt so hell, dass sie im Amiciprisma einen langen Spike erzeugt, wirkt sehr reinweiß - Komponente B erscheint warmbraun - bei 20-fach ist B auch noch gut zu erkennen, der Farbeindruck ist nun jedoch schwächer und B wird zu einem mausgrauen Punkt |

This is rapidly closing and will be at periastron by the middle of 2022, opening again and should be better detectable again by 2029 when it will be 0.208". 17.962-year period |

Very tough at this aperture, I suspected it at 205x but can more consistently see it with 333x. A is a light orange star and B splits but is very tight, needed averted vision at first but it brightens and holds with foveal coaxing, but it s very faint indeed. Physical with a 192-year period, it's now at apastron and will stay there a while |

Handheld in reclining chair, binoculars with internal stabilisation. 14 May 2022 (4.7" angular distance according to database): Pear-shaped. Strong orange-lemon yellow, a fruity affair.

21 May 2022 (4.7" angular distance according to database): Hairfine split, slightly difficult due to bloated stars in these achromatic (not apochromatic) binoculars. Both components orange, with secondary going into yellow. Thin cloud moving through tightens up the star images and makes the split much clearer. Clearest shortly before clouds become so dense as to swallow the pair. |

Handheld. Wide split but secondary very faint (NELM 5m1 in target area). STTA104 one degree to the northeast has practically identical separation yet is much stronger. The charm of this pair resides less in its visual appearance than in contemplating that it is a physical double at a distance to us of 287 light years. |

Handheld. Wide, striking matched pair. Nice together with triangle of 27/28/30 LMi, and thus also easy to find. HJL1057 also in field to southwest. Delicate colour contrast in the triangle makes this a very attractive field: 30 LMi is yellowish-white, 28 reddish-white, 27 LMi colder. In 15x45 binoculars STTA104 becomes almost too wide to feel it is a double, but the colour contrasts in the triangle become clearer. |

AB: Wide apart and large delta-mag, but still very much belonging together. No particular colour impression. Smart 75 AB (also known as Shaya (SHY) 216) is a physical double at a distance to us of 121 light years. This is incidentally almost exactly the same distance to us as Alpha UMa AC, a further wide binocular pair in UMa. |

A wide pair but still appearing visually to belong together. Component A is a creamy gold-white. Component C is pale blue, but the colour impression fades after looking for a while. In parallel observation with 3-inch at 32x and 7-inch at 67x I see no particular colour of C, an interesting difference to observation with one-and-a-half-inch. I take a look with 7x42 binoculars and the blue impression is there again, as always with binoculars of all kinds. |

A is a very light orange, and when seeing stills and the diffraction rings are steady, B appears as the tiniest fleck, well outside the first ring about 3", a deeper duller orange color. Physical. Burnham discovered with the 18.5-inch Washburn refractor at 1.8" -- his extra aperture helped as mine is wider but with just a 7-inch, and explains why Struve never saw it. He wrote: "It is obvious from the measures that this belongs also to the small star, and they must form a physical system." |

Mark McCarthy

Bright light orange star. As seeing resolves it to a disk and eliminates the diffraction, a tiny, faint star appears, planet-like, (~3") from the star. Only at the best moments, visibility of B star helped by averted vision. |

Cream white A and can see B nicely separated, about 3". Used averted vision at first to see B, then could hold direct after foveal coaxing |

Mark McCarthy
Fremont (California/USA) |
762mm (457x) |
The pair split immediately at 457x. A little diffraction but no doubt a small blue point just outside the first ring. Using the 8-inch aperture mask (effectively 8-inch f/18!) had a nice star image of A but B disappeared -- it became an averted vision, threshold object. Barlow here was no help to show it better. I think Ho 50B is fainter than the current data, and if the older data say it should be fainter, then it may well be variable. However, later in the night, I estimated Ho 50B to be as bright as STF 1964D, which is 9.02 |

On tripod. Neat split. Attractive 6.3° FOV with a sprinkling of several 5- to 7-mag stars to the south. Tau Leo widely split directly to southeast. In 15x60 on tripod well split, component A slightly orange, forms a fine double-double with Tau Leo. 83 Leo is a physical double at a distance to us of only 58 light years. |

With 12x36 binoculars the pair is very wide and only just still seeming to belong together. With 15x45 binoculars already too far apart for a double-star impression to arise.

bei 20-fach ganz knapp getrennt mit einem deutlichen Helligkeitsunterschied - für einen Farbeindruck reicht die Vergrößerung nicht aus - bei 49-fach färbt sich die Hauptkomponente sehr schön roségold - der deutlich schwächere Begleiter wirkt nun grau-bräunlich - das Sternumfeld ist dank lose verstreuter Sterne in einem großen Bogen von Norden über Osten nach Süden um den Doppelstern herum besonders schön |

28 February 2021 at 3" separation: Very slight elongation. PA estimated at 5° (thus only 9° off, which seems fairly precise to me considering the low power of 15x and the minimal elongation, both of which make PA estimation difficult). Intentionally flashed the eyes on the almost full Moon directly prior to observation in order to enhance acuity. Compared the sight of Porrima repeatedly with that of similarly bright Epsilon Vir (Vindemiatrix) to check whether the elongation is perhaps an artefact of the bincolulars or of my eyes, but no elongation seen there. |

Seeheim (Germany) |
15x45 |
Binoculars with internal stabilisation, handheld. AB cleanly split with distinct difference in magnitudes. Strong visual presence of this physical double is enhanced by the complete lack of visual competition in 4.5° FOV. Interesting to contemplate that in the 9th century AD Struve 1694 was just as close to the celestial north pole as Polaris (also a physical double) is today. Also known as 32H Cam, which comes from the celestial map produced by Johannes Hevelius in the late 17th century. |

Well apart but by no means falling apart, and totally dominating the 3.2° field of view. Neither component would appear particularly colourful on its own, but viewed together the primary is definitely more on the orange side and the secondary more bluish. At 25x in 3.2° FOV and with an exit pupil around 3mm making the sky background pitch-black, STF 1694 has such a strong visual impact that it becomes a showpiece specimen of a double star. Three-star rating awarded because of this strong visual presence plus binocular accessibility (see 7x50 observation) plus true physical nature of the double (according to Stelledoppie) plus pole-star role in the Middle Ages. |

Split clearly, so clearly that I stumble across the pair while panning through the area. Primary seems yellowish, an impression confirmed by observation directly afterwards with 71mm refractor at 32x, in which the primary is distinctly yellowish and the pair visually very strong. |

Wide apart. Would probably no longer feel like a pair in a crowded Milky Way field, but here, not all too far from the North Galactic Pole, the two components hold together well (and are indeed a physical pair). Very attractive 4.5° FOV to south with east-west string of stars followed by fluffy ball of globular M53 and finally brilliant Alpha Com. |

Mark McCarthy

80mm (13x) |
Wide finder split, 1 delta mag, not much to recommend. Triangle of stars to the south, pointing to Bgh 46. [I did look at this at 667x to see if one of the wide pair had a pair of its own, but did not scrutinize well enough. This one should try on a really good night with 20": HDS1862 = Aa,Ab 6.56/9.69 0.4".] |
|
Mark McCarthy
Fremont (California/USA) |
178mm (205x) |
Super-wide pair even in the finder, and I am very surprised to see it is listed as physical, at least as proper motion is concerned. The close pair HDS1862Aa-Ab I thought I saw but it is too fleeting, seeing not supporting higher magnification. Reviewing the Gaia DR3 data, which includes parallax, it confirms there is overlap in the weighted distance but the weighted separation of the pair is 19,121 AU, which means this is very likely not a physical pair |

AC: perfekte Bedingungen: der Doppelstern steht im Zenit, gute Transparenz … und siehe da, das kleine Reiterlein Komponente C ist zu erkennen, ach was sage ich, leicht zu erkennen - C ist deutlich schwächer, Trennung mehr als knapp - heute so einfach, wie oft bin ich im Vorfeld gescheitert mit bloßem Auge |

AC: Mizar/Alcor: After seeing the two stars separated for the first time under clear corona skies in spring 2020, this became a regular and easy sighting. Naked-eye star splitting is a skill that develops rapidly with practice. Mizar and Alcor are wide apart with my 60-year-old eyes, and occasionally Alcor appears slightly bluish. |

On tripod. Mizar (AB) is an uneven figure-8, the smaller circle of the 8 pointing to an estimated PA of 150°. Without knowing that this is a double star one might think the binoculars have collimation issues, but Epsilon UMa displays a perfect little Airy disk. Alcor (C) appears bluish, Mizar creamy-white. D seems reddish. |

70mm (10x) |
AB: 2020-04-12: Observation from city with a 70/400mm ED refractor, for which I made aperture masks from 10mm to 60mm. Goal was to find the minimum magnification for a successful split.
70mm: At 12.5x no separation of the components possible due to outshining. Grey filters brought a slight improvement, but again no separation or elongation was visible.
60mm: At 12.5x slight outshining of the companion, clearly elongated and almost separated.
50mm: At 12.5x the companion was almost outshined. A separation was just possible.
40mm: At 12.5x both components appear finely separated from each other.
30mm: At 10x not clearly separable due to outshining, but clearly elongated. At 12.5x then quite easy to separate with a fine star rendition.
20mm: At 10x the companion is still clearly visible, but quite close to the primary component. At 12.5x best view under the used apertures with a very fine rendition!
10mm: At 10x the companion appears very faint. Separation possible, but extremely tight. At 12.5x reasonably well separated. |

70mm (22x) |
AB: 2020-04-11: At 12x no separation possible, because the bright primary component outshines the companion. At 22x clearly separated, but still quite close together. |

White stars, well split ~6", about one delta. Surprised this was not discovered until 1901 by amateur British astronomer Edwin Holmes, who was a "seller of glass" and made his own 12-inch Newtonian. Apparently he was strongly opinionated and argued for the use of reflectors over refractors for their large aperture at low cost |

At a position angle of roughly 265° I had the feeling something was going on; a kind of protusion of the primary, coming and going. 200x: yes, now a stellar condensation kept popping in and out of sight at the same position, just on the outside of the first ring, which itself was coming and going in not-so-perfect seeing. Upping the magnification to 240x and 300x didn't improve the view. |

AB: 2020-03-16: 102/1122mm ED refractor stopped down to 60mm. The diffraction ring of the primary component is virtually invisible. The companion appears only in few moments as an extremely faint, elongated brightening in the diffraction ring. Very difficult. Telescope should be in very good optical condition! |

AB: 2020-03-19: At 150x the clearly fainter companion is visible as a roundish brightening. Due to the chromatic aberration of the achromat (152mm f/5.9) the companion is almost outshined. At 180x the companion is then well, at 225x and 300x very well visible as a tiny separated star. |

Lightest orange, notched elongation to snowman at best moments. Burnham discovered in 1878 with the Dearborn 18.5-inch, and in 1899 wrote: "It was very soon apparent from the measures that this was a binary system in rapid motion. In the twenty years covered by the measures, the companion has passed over an arc of 175-degrees. Glasenapp…has computed an orbit from which he finds a period of 30.00 years....This represents the observations as well as could be desired, but evidently the arc was too short for any very accurate determination, and even now widely differing apparent orbits will satisfy the observed positions equally. It is probably that the measures of the next ten years will furnish sufficient data for an orbit which shall substantially correct." In the period since, there have been many measures, and a grade 1 Definitive orbit is established. WDS lists it as physical with a 22.46-year period, currently at 0.1 but will widen to 0.3" by 2030 -- I can hope for a clean split by then |

AB: With handheld 7x42 binoculars I cannot separate B from A. With handheld 10x42 binoculars with internal stabilisation, B emerges in fleeting moments from the glare of A, wide. Yellow-orange hue of A that I had already noticed with 7x42 binoculars becomes clearer with 10x42. With stabilised 20x60 binoculars I can hold B constantly, but B is far more difficult than component C (AC = Shaya 633) despite B and C having practically identical brightnesses.
AC: With handheld 7x42 binoculars component C is clear and very wide from A. A seems yellow-orange. Not visually exciting, it is nonetheless pleasurable to contemplate that this is in fact a physical pair travelling together in space, 317 light years distant from us.
SHY = E.J. Shaya, R. Olling, 2011: Very Wide Binaries and Other Comoving Stellar Companions: A Bayesian Analysis of the Hipparcos Catalogue. Component A is HIP 67250, C is 67041. AB is also physical, hence ABC is a triple system. |

Wide, white, half delta. WDS says it's physical but I calculate no parallax overlap and the two are too far apart to be gravitationally bound |

At this power very wide, slight delta mag. At first sight no evident colour contrast, but after a while it becomes increasingly clear that the secondary is bluer than the primary. This effect is rather charming. |

STF1831 (AC): Wide split at 7x but still a very distinct impression of being a double. No colour impression. Two fine pinpricks of light, rather attractive in 8° FOV. According to Stelledoppie the A-C pair, at 509 light years distance to us, is the only physical pair in the whole STF 1830/1831 complex. A nice physical double for small binoculars. |

The C component in the middle appeared white-yellowish, AB rather white with a slight tendency to blue. At 57x, the pair AB with a clear difference in brightness can be easily split. An altogether rewarding and unusual multiple system. |

On tripod. Well split, companion seems bluish. Fine 3.3° FOV star field with Kappa Boo (also split) and Theta Boo plus several 6th to 7th mag stars. Iota, Kappa, Theta were called Aselli by Johannes Bayer in the 17th century, meaning The Donkeys. The group is found easily naked-eye under a 5mag sky. Iota Boo is Asellus Secundus, The Second Donkey. A physical double at a distance to us of 95 light years. |

bei 20x sind alle drei Komponenten direkt erkennbar - die mittlere Komponente B steht leicht südlich versetzt und scheint der schwächste von den Dreien zu sein - bei 32x sind alle drei Sterne gut getrennt und C steht näher zu B als A - Farbe ist nicht wirklich feststellbar, aber der C strahlt ein wenig klarer (nicht heller), A und B wirken etwas dumpfer, fast so als würden sie zum Orange tendieren |

AB: 5 stars in the system, but only 3 are bright enough for me to see with 7-inch, they form an arc (like a jumping dolphin) of near equal stars. WDS says AB are physical and my calculator agrees, which is a surprise given the very wide separation -- they are relatively close stars so appear wide |

30 May 2021, current separation 0.65” according to Stelledoppie. No prior PA knowledge nor knowledge of relative brightnesses. Constant elongation seen. Definite determination of position of the primary within the elongation, more definite than the relative brightnesses (consulted after observation) would have led me to expect. PA estimated at 60°. In good moments fragments of a pear-shaped first diffraction ring surround the system, particularly on the side of the primary. An interesting and attractive sight. |

With more time observing & getting used to the image, and in moments of better seeing, the notch became more distinct. It would not separate in spite of moments of better seeing. I could also see the elongation, but only subtly notched due to the smaller scale, at 667x |

AB: Noticed with naked eye and without prior PA knowledge that a secondary was flickering next to Zubenelgenubi. Unexpected and first naked-eye sighting. Checked position with binoculars to be sure. Further naked-eye look at Mizar/Alkor (Zeta UMa) to gauge my momentary acuity and assess the difference to Alpha Lib. Zeta UMa more easily and widely split than ever before, and Alkor appeared for the first time bluish, so this was an exceptional night for naked-eye double-star splitting. Three-star rating awarded because Zubenelgenubi is the second-best naked-eye true-physical double star in the summer sky after Mizar/Alkor. |

Ice blue white A and slightly orange B, two delta mag, wide. WDS calls this physical on the strength of the proper motion data, however Gaia shows there is no overlap in the parallax range, so it is not gravitationally bound. Also the escape velocity far exceeds the radial velocity delta, so another strike against it |

Wide white stars, half delta mag, one tip of triangle of slightly fainter stars. WDS says this is physical on the strength of the proper motion data, but Gaia shows there is no overlap in the parallax range, so it is not gravitationally bound |

Beautifully split with 533x, very clear, slight delta mag, light orange stars. It's a little challenging at this magnification with the small scale; the stars were elongated at 205x. WDS uncertain of physicality; Gaia shows no parallax overlap, so sadly this is not |

White stars, 1 delta mag, wide. Stelle Doppie gives AB as physical with a 4.23-year period, and an orbital plot -- but with separations of 0.02-0.04". Checking the WDS notes, I find: "AB: Radial velocity variations, based on 10 years of monitoring, indicate the presence of a giant planet orbiting the B component, with P = 1544 +/- 34d, a = 2.62 +/- 0.04 au. M sin i = 1.49 +/- 0.09 Mjup. The primary is an SB in an eccentric orbit with period 25-30 y; mass of Ab 0.5-0.6 Msun. No companions were detected by AO imaging." So it seems SD is giving the orbit of the giant planet! |

STFA28 (AB): Handheld. Wide split. A compact uneven pair. Component A is bluish-white. Rather charming in 8.6° FOV with Nu1/2 Boo, which has a gorgeous colour contrast, golden-orange and ice-blue, making it one of the strongest colour-contrast pairs in the sky for binoculars and greatly accentuating the sight of Mu Boo. In 15x45 binoculars STFA28 AB is very wide, component A bluish-white, B warmer. |

Hier handelt es sich um ein Dreifachsternsystem, welches jetzt aber nicht durch eine besondere Färbung der Sterne auffällt. Die A - B/C Komponenten stehen noch sehr weit auseinander, wobei auch die A-Komponente um einiges heller erscheint. Die beiden Komponenten B/C sind wesentlich näher beieinander und unterscheiden sich auch kaum in ihrer Helligkeit. |

Challenging near equal stars, one fades with seeing then when settled it makes a nice close around 2" split with the other. This is gravitationally bound: 25% parallax overlap, 378 AU separation, and the escape velocity is less than the radial velocity difference |

2021-08-20: The pair AB-C is easily visible already at 28x, with C being the brightest component and standing apart quite far from AB. At 86x the much closer pair AB is then also easily visible. The separation is easy, but the companion B is quite faint. Component C appeared slightly yellowish, A a bit darker. A nice triple system, which reminds me of mu Bootis. |

Stabilised binoculars, handheld. Difficult handheld in this instrument, but clearly split and attractive as such. Tripod mounting would surely help and make the difference for a nice pair for this magnification. One of the earliest doubles split, found by Benedetto Castelli in 1627, but according to Stelledoppie not a physical double (in contrast to the very tight BU 947 AB pair in the system, which is physical, with a separation of 0.3” in 2020 and 0.4” in 2030 – and the wide PWL 9001 AD pair with a separation of 518” – A, B and D are thus a physical triple). “H“ in the catalogue name means that this double star is listed in the catalogue of W. Herschel. The 3 in the name means that it is a double star of the 3rd Class [separation 5'' - 15''] in Herschel’s system. |

bei 64x sind die Sterne so schwach, dass ich hellere Sterne im Umfeld zum Fokussieren nutzen muss - beide Komponenten sind als 8 erkennbar, die Einschnürung ist aber nur in guten Momenten da - bei 107x dann gelingt die Trennung, B wirkt deutlich schwächer (in Wirklichkeit ist B nur 0m4 schwächer), aber vielleicht liegt es daran, dass die beiden Sterne ohnehin nur sehr schwach beobachtbar sind - das hat wenig Freude bereitet |

Clean split. Separation is much clearer than that of Nu1/2 Dra (STFA35), which is also in 14° FOV and is hair-fine split. A physical double at a distance to us of 412 light years. |

Christopher Hay
Seeheim (Germany) |

A well split and nicely compact pair. When 16/17 Dra is put at the edge of the 8.6° field of view, Nu1/2 Dra stands at the opposite edge. Their comparison thus suggests itself. 16/17 is somewhat wider than Nu1/2. While the components of Nu1/2 are of equal brightness and whiteness, those of 16/17 display a slight difference in both brightness and colour. 17 (A) first seems bluer than 16 (C), but after 20 seconds this impression flips to C and from then on goes back and forth. |

16 Dra seems more bluish than 17 Dra, the latter seems slightly yellow in comparison and is distinctly elongated. At 84x 17 Dra is cleanly split and such a delightful view together with 16 Dra that I had no desire to ramp up the magnification. All three stars belong to a physical system. |

I sensed elongation with the 8 inch mask at 333x, but it was a haze only flashing elongation with averted vision. With the 20 inch the a star resolved, orange, and the B was noticed at 3" but was considerably fainter, I would guess 1.5 to 2 delta mag. |

! Wow! 3 delta mag B star just outside blue-green A's diffraction ring. Seen at both 175x and 285x. J.J.M. Perry. Uncertain in WDS, but from the Gaia EDR3 data I find a 23% parallax overlap, 2030 AU weighted distance, with the primary star 3.31 primary star solar mass vs 1.61 for the secondary -- so it should bind at 2030 AU -- so it is likely gravitationally bound. Gaia lacks the radial velocity otherwise I could confirm it |

Very interesting. At 20 inch the a star was orange and bloated with the seeing, did not notice a pair. I used the 8 inch mask which tightened the A star up considerably, then with averted vision could discern a very faint small glow in one particular direction, but could not hold it direct. Back to the 20" and now in good moments I can see the B star quite well, 5 delta mag, bluish. 333x |

36mm (50x) |
At 50x secondary detaches momentarily from first diffraction ring of primary as the tiniest pinprick of light, delta-mag seems massive. At 66x separation becomes much clearer. Can hold secondary 80% of the time as a fine point on the outer rim of the first diffraction ring. Primary is orange-yellow, secondary far too faint in this aperture for any kind of colour impression. Rather charming in a strange sort of way. See for comparison simultaneous observation with 210mm at 68x. |

At 133x split well and showing a fine colour contrast, orange / grey-blue. Each step to 160x, 200x and finally 266x benefits the aesthetic experience, drawing the pair apart and making the colour contrast clearer. At 266x primary is yellowish orange and secondary exhibits a fine grey-blue. Fine diffraction pattern at 266x with first ring around secondary and hint of a second ring around primary. |

bei 96-fach ein sehr enges Pärchen mit einem weiten Lichthof, das hübsch umkreist wird von etwa einem halben Dutzend schwacher Sterne – beide Komponenten leuchten in einem warmen Gold, die Hauptkomponente deutlich heller und stärker |
|
Christopher Hay
Seeheim (Germany) |
254mm (170x) |
At this power the components are drawn far enough apart, and there is enough exit pupil with this aperture, to clearly see a charming contrast of two different types of yellow. The primary is distinctly orangish, while the secondary is lemon yellow. The FOV of a little under 0.5° frames the pair well. At lower powers the primary swamps the secondary and both appear similarly orange-yellow. |

Can see it steadily split at small scale at 205x, bluish stars at one corner of a triable of near equal magnitude stars. I get a wider split but needing more averted vision at 445x. Discovered with his 6-inch, Burnham notes: "It is the s star of a small equilateral triangle, all in the field." No parallax overlap, not physical |

I suspected B was also a pair at 333x, and could get a nice clean split with seeing at 533x, so I could tell an orientation and make a sketch (43-year period). Indeed it is a short period pair and I should be able to get at least a quarter turn out of it |

90 Her. Orange star with one part of the airy disk persistently brighter but which does not resolve to a disk. Tried up to 380x. The slightly brighter primary made this more difficult than PRY 2. This was one I wanted to try since Burnham discovered it with his 6-inch. He writes: 90 Her. "…a beautiful pair, even with small aperture. The components have a striking difference in color -- golden and blue….[due to common proper motion] there is little doubt of its being a physical system." WDS uncertain after 49 measures. Unfortunately Gaia lacks the parallax measurements for the B star |

90 Her. Need stillness, it coalesces from the diffraction to a light orange point at 553x (grey at 885x). No doubt about it, star, point light. For the first 10 minutes of observing seeing allowed me to glimpse it 1 of every 10 seconds. But after a while seeing was better and I could hold it pretty consistently in both magnifications. At 553x it's in the first ring, at 885x it's in the second. |

Stabilised binoculars, handheld. Components wide apart, almost too wide to appear as a double star. Secondary a fine speck of light beside the primary, which is >4mag brighter. According to Stelledoppie a true physical pair at a distance of 1230 light years. It is interesting to contemplate that at this distance in space the companion still looks so separate. “H“ in the catalogue name means that this double star is listed in the catalogue of W. Herschel. The 6 in the name means that it is a double star of the 6th Class [separation 1’ or larger] in Herschel’s system. |

Very far apart, almost so far as to appear to not belong together. However, in the 3° field of view 70 Ophiuchi, which is also a physical double, is seen to be also split. Thus a very attractive field overall. 67 Oph and 70 Oph are the left and right nostrils of the bull in the old constellation Taurus Poniatowski (Poniatowski’s Bull). 68 Oph (the tip of the bull’s nose) and 73 Oph (the bull’s right eye) are also double stars, but can’t be split at 25x. All four doubles – 67, 68, 70 and 73 Oph – are physical, a rare assemblage! |

AB: wenn man bei 32x genau hinschaut, ploppt westlich von A in halbem Abstand AC ein schwacher Lichtpunkt aus, das ist Komponente B … ohne Farbe, weil sehr schwach - auch 64x verbessert die Sichtbarkeit von B nicht wirklich AC: bei 32x fallen die fast gleich hellen Komponenten A und C (nördlich von A) des Dreifachsystems auf |

Faint pair, so the colors might be a little exaggerated. Ice blue A and reddish B, wide. Spectral is K0, yellow-orange. WDS says it's physical, and it looks that way: only 5% parallax overlap, but a 1,790 AU separation, and the A star stellar mass is 2.6 and B is 1.9. The difference in radial velocity is less than the escape velocity, so it may well be gravitationally bound |

Very much fainter B seen with averted vision and foveal coaxing only, can only hold it briefly. Physical with a 951.7127-year period (to be exact), it is now making a very fast turn around apastron -- though I think the orbital solution is predicting an incorrect position (too close to apastron at this moment) -- unfortunately I did not record the PA so I can't tell if it's on the west or east side of apastron. Will need to re-observe this, since I don't think I'd see 0.2" at 533x (likely around >0.5" given the delta mag) |

STT351 (AC): Orange stars, noticeable magnitude difference ~0.5, separated just less than ~1". What's curious is the AB pair is HU 66 AB listed as 7.90/8.40 0.1" currently, with HU 66 BC as 8.40/8.25 0.9". So my question is, if AC is physical, and if BC are physical too, why is AC uncertain? It would seem they should all be sharing orbits? Perhaps it just cries out for additional measures -- AB is grade 4 and BC is grade 5, so they are confident of physicality but there's not enough data to nail it down. |

Very challenging.

Stelle Doppie says first measure of this pair is in 1901, so it's not a Struve discovery, likely Aitken or Hussey with the Lick 36-inch |

Komponente A ist leider so hell, dass ich die wesentlich schwächere B-Komponente erst bei 57x außerhalb des Lichtkranzes von A erkennen konnte, Trennung mehr als komfortabel - zurück auf 29x kann ich B jetzt auch erkennen - trotzdem ein extrem unansehnliches Sternpaar |

Appeared as an ordinary white star. There was no secondary listed in SkyTools so I didn't know what to look for, and didn't notice the 11.90 B star listed in WDS (it was probably too faint for 7-inch anyway). TRA is Veselka Trajkovska who has this one discovery to her name (but numerous measurements made of other stars) using the 25-inch refractor at the Belgrade Observatory. The B star might not be in Gaia, but if I have it correctly it is 13.02 mag and they do not share the same parallax range, so they are not gravitationally bound |

naked eye |
STFA37 (AB-CD): While waiting for Comet Neowise at 3 in the morning in July 2020 surprised myself with my first naked-eye separation of Alpha1 und Alpha2 Capricornis (observing site at 50° northern latitude, Alpha1/2 passing through meridian). Encouraged by this, I lay down and had a close look at Epsilon Lyrae, without really expecting to be able to split it naked-eye, having never succeeded previously. At first Epsilon Lyrae appeared as a very short dash of light. Then the dash resolved into two pinpoints. After 15 years in the hobby and at age 60, at last got Eps Lyr split! No precise prior PA knowledge. After memorising PA as seen naked-eye carefully, confirmed it with binoculars. Eps Lyr is the third-easiest physical double in the (northern hemisphere) summer sky for the naked eye, after Zeta UMa (much easier) und Alpha Lib (marginally easier). |

AC: I had strong visual color response, though the disks were somewhat bloated with seeing: A was blue-white, B was yellow-white, and C red-orange. Colors were the same at 100x but the disks smaller. With an 8-inch mask at 205x, the disks were tight and overall everything was fainter. C was less red, more grey, and much fainter, so the color was not so strong and maybe would not be described as orange |

White A and can see B first with averted vision and then can hold with direct, 3 delta mag, wide. Not physical per WDS, but this is incorrect! 4% parallax range overlap but only 55 parsecs; 300 AU weighted separation, and 1.08/0.64 stellar mass; and the radial velocity delta (1.07) is less than the escape velocity (3.18), so it is gravitationally bound! |

bei 103x zeigt sich das Sternpaar ein wenig mehr als knapp getrennt - B steht nordöstlich von A und wirkt wie so oft grau wegen des Helligkeitsunterschiedes, den ich auch 2 bis 2.5 Magnituden schätze |

V595 Lyr. Very tough! In unsettled seeing it is an elongation or lopsided at all powers. However at best moments it tightens enough to show a very subtle notch & also different brightness and color, A being light orange-yellow, and ~1 delta mag B a deeper orange. Discovered in 1902 at 0.2, it has only a 14.64 year period, it will make a rapid circuit to the other side by 2026 (though only 0.1"), and "widen" to 0.2" again by 2030. Should be fun to observe! |

Colour of C is more striking than that of A, in a manner similar to my simultaneous observation with 60mm at 15x, but not quite as pronounced. C has a companion set off from it by a hair of black. I estimate PA from C at approx. 80°, separation very roughly 2". Surprisingly can't find this companion in the double star catalogues. |

Unremarkable, wide, 1.5 delta magnitude white stars, maybe in a triple as a third star a little farther out forms a triangle (this is AC). Not physical per WDS, and no data on the companion in Gaia. W.A. Cogshall, assistant to T.J.J. See at the Lowell Observatory, but by 1903 he was observing with the 12-inch at the Kirkwood observatory where this discovery was made, following a list made by Burnham of stars suspected to be double by the Albany observers |

AB are near equal and wide, BC is very slightly fainter, well split itself. It appears as a slightly hooking line of three stars. 9 stars in the system. WDS says this is physical due to parallax, and it appears it is: 3% of range overlap but it's only 549 AU separated, stellar mass 0.90/0.85, and the radial velocity delta is less than the escape velocity |

FF Aql. Lovely deep orange A with very faint bluish well separated B, just detected and held with direct vision. WDS is uncertain, but there is 8% parallax overlap, 3,508 AU weighted separation, and high stellar mass 6.74/1.75, so may well be gravitationally bound |

bei 29x einfach, A und BC stehen ordentlich auseinander und haben einen ordentliche Farbkontrast, der aber immer hin und her zu springen scheint - zurück auf 18x ist das Pärchen noch immer gut getrennt zu erkennen - der Doppelstern ist schön anzusehen, er wird im Westen von einer gebogenen Kette aus sechs Sternen flankiert, die sich wie eine Schnecke einkringeln (ein großer Bogen, der immer enger wird) |

bei 32x ist A schwach und orange, B südlich ist gut getrennt erkennbar, noch schwächer und farblich nur noch als "dunkel" zu bezeichnen, dadurch aber ein auffälliger Farbkontrast -runter auf 20x kann ich B leider nicht orten - der Doppelstern bildet mit einigen 7-9 mag hellen Sternen nördlich ein markantes Muster wie ein Angelhaken (oder einer Häkelnadel, wenn man bedenkt, wie eng der Bogen südlich geschwungen ist) - STF2442 bildet dabei die Spitze der Rundung des Hakens - sehenswert innerhalb dieses Musters |

Widely split. Attractive together in 0.8-degree FOV with Struve 2455AB a little less than half a degree south. The secondaries of the two doubles point towards each other, a nice sort of double-double. According to Stelledoppie 2457 is a physical double, while 2455AB is not. In 2457 the brightness of both components is less than those of 2455AB, their separation greater, and their colour contrast (itself hard to define) is greater. In 2455AB focussing on the A-component precisely is hard to achieve, perhaps due to an unresolved field star very close to it? |

Light orange stars, obviously not single at 445x, and the disks separated as I powered up. Less than 1 delta mag, the best view with 889x, which showed a constant hairline split even with wavering seeing, PA NNW. A really nice pair. Spectral class A8III (white). 121.7-year period, currently 0.328" separated, it is approaching apastron now and will hang there until the 2050s. Burnham discovered in 1889 on the Lick 36-inch at 0.3" and noted "If [the proper motion in Ast. Gess. Catalogue]...is substantially correct, this is a physical system." |

Handheld binoculars in reclining chair. Following a surprisingly easy split of Zeta Lyr, I try out whether Albireo may also be splittable. Indeed, the pair is split, difficult but definite. Staring at Altair (Alpha Aql) for a few seconds with the binoculars prior to observing Albireo heigtens my acuity and makes the split more definite. Component A exhibits a mild orange-yellow hue. |

Primary ruddy red, secondary wide apart but too faint for any colour impression. Straw-yellow Epsilon Saggitae half a degree to the west with its ice-blue eastern companion enhances the experience of colour contrast in the FOV and is actually more attractive than HN 84 with this aperture and power. |

Christopher Hay
Seeheim (Germany) |
150mm (96x) |
Main component ruddy tangerine orange, companion wide apart and ice blue. The longer I look the stronger the colour contrast becomes, which is by no means normal in many doubles. Epsilon Saggitae in same 0.8-degree field of view is straw-yellow with a cold blue companion (a field star?) pointing away from Epsilon in the direction of HN 84. I can’t think offhand of a better colour-contrast pair that can be framed in this manner in the same FOV. |

Self-built binoculars, hence the unusual specification. Made of top-quality teleconverters, apochromatic and sharp to the edge. With naked eye under good suburban sky 16 Cyg is just seen. In the 3x binoculars the double is split into two finest points of light in good moments despite the low magnification. A physical pair according to Stelledoppie.
Two-star rating awarded because this is a true physical pair that can be split with the smallest binoculars and reveals increasingly more with growing binocular size (brightness disctinction between A and B in 7x50, colour distinction in 15x45). |

AB: bei 32x fällt das Paar sofort auf - Komponente A im Osten ist gut 2 Größenklassen heller als B - schöner Farbkontrast aufgrund des Helligkeitsunterschiedes, Komponente A strahlt weiß mit einem Stich ins orange, B ist grau - bei 20x ist die Trennung auch einfach AD: bei 32x von A und B ausgehend ist das der nächste erkennbare Stern im Umfeld, er steht etwas weiter südwestlich und ist gut viermal soweit von A entfernt wie B - Komponente D wirkt noch gräulicher und transparenter als B - Komponente B dagegen wirkt schon wieder weiß im Vergleich zu D - bei 20x sind auch alle drei Sterne sichtbar |

AB: bei 30x ist die A-Komponente des ordentlich getrennten Sternpaars richtig schön hellgelb, B im Südwesten strahlt leicht rotorange, beim direkten Betrachten jedoch nur noch grau, A ist der hellste Stern im Umfeld - bei 60x macht das Paar durch die strahlend gelbe A-Komponente auch einen schönen Eindruck, B bildet wieder einen schönen Kontrast AD: in etwa vier- bis fünffachem Abstand südwestlich ist D als weitere Komponente zu sehen, die sich nur minimal schwächer als B zeigt |

AB-C: Secondary nicely set off as a fine pinprick beside the much brighter primary. Secondary seems ice blue at first sight, but that impression fades the longer I look. Primary essentially colourless. Secondary not seen in 3-inch at 30x. Physical double according to Stelledoppie. |

Christopher Hay
Seeheim (Germany) |
150mm (300x) |
AB: Used a moment of unusually good seeing in July 2019 to find out whether anything can be done with the 6-inch on this super-tight pair. No prior PA knowledge. At 200x nothing happening. At 240x a northwest-southeast elongation. At 300x distinctly stretched. According to Stelledoppie a physical pair with a very short period of 23 years. Distance a little over 0.2“ from 2010 to 2020, shrinking to 0.03“ in 2026, reaching 0.2“ again around 2040. This is one of very few double stars whose complete orbit can be observed several times over in a human lifetime, be it only as a periodical elongation/contraction. The observability of the elongation in just 6 inches of aperture is aided greatly by the almost equal brightnesses of the components. |

WDS says physical and there is 17% parallax overlap, 2,874 AU weighted separation, and stellar mass 2.29/0.96, so may be gravitationally bound |
