41 Lyn (**)

Name: 41 Lyn, S598

This star has the designation 41 Lyn but is assigned to UMa. At the time, when Flamsteed numbered the stars, the constellation boundaries were not exactly defined. Another example is 10 UMa, which is located in Lyn today.

2020-04-05: The pair AB stands out immediately and shows itself in beautiful colors: A white-yellowish, B slightly orange. Almost at right angles to pair AB component C is visible as a faint star at a slightly smaller distance. I did not pay attention to the even fainter component D.

2020-04-05: Components A, B and C easily visible with decreasing brightness. I did not consider component D. A: white-yellowish, B: pale orange. I liked the view in the 8x40 binoculars better.

At 22x, all three components are already visible, with A & B still standing quite close together. Component C is less prominent. 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! Note to the sketch: The positions of the stars to each other do not exactly match, also the alignment of the pair AB to C.

STF1831 (AC): 2020-04-05: Fairly wide pair with slight differences in brightness and color. C appeared slightly orange, A on the other hand slightly bluish. Comparatively bright double star, which gives a nice view.

55mm f/9.1, 27x
STF1831 (AC): 2020-04-05: Moderate difference in brightness. C: pale orange, A: subtle blue.

70mm f/5.7, 57x, Bortle 6
2020-04-11: At 22x the components AB, C, E & F are well visible and widely separated. E & F are comparatively faint. 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.

Relatively thin, very elongated, darkened toward the edge, slight broadening toward the middle. Easily seen with averted vision, while a nearby group of brighter stars interfere!

die Superthin sitzt südlich einer flachen Bananenraute aus vier hellen Sternen - bei 72x ist an dem südlichen der vier hellen Sterne immer eine Reflexion auszumachen, die so an den anderen Sternen nicht sichtbar wird - bei 111x wird die Sache dann eindeutig - die Galaxie zeigt sich 4:1 elongiert und reicht bis fast an den schwachen WNW-stehenden Stern - wenn man sie geduldig indirekt anvisiert, zeigt sie sich als lange dünne Spindel und scheint nach Vergleich mit DSS fast auf der vollen Länge sichtbar - kurios

AB: 2020-04-05: Even with tripod not separable.

70mm f/5.7, 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 f/5.7, 22x, Bortle 6
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.

First pastel sketch (Pitt pastel by Faber-Castell) of a double star on black paper, where also the halos were sketched around the stars. The stars themselves were redrawn with an Edding (Edding 1500, Soft Pastel white). The sketch shows the components A to D.
