- Thin Galaxies (Lyn) -

Here I will present some quite thin galaxies with an axis ratio of at least 1:5. Nevertheless this value is calculated from the given angular size, so the visual impression can differ.

IC2233 (GLX)

../dss/dss2blue_081358.91_+454431.74_5_web.jpg
Image source: DSS II (blue) - 5×5'
Name: IC2233, UGC4278
Type: GLX
Constellation: Lyn
Coordinates: 08h13m58.91s / +45°44'31.74"
Brightness / Size: 12m6 / 4.6x0.5'
120mm f/5, 85x, Bortle 4, SQM-L 21.0
The 13.07 mag star in the northern part of the galaxy I could easily see with averted vision. The galaxy stayed hidden.

FAILED
8" f/6, 150x, Bortle 6+, NELM 5.2, SQM-L 19.6
At 100x just a hint of a galaxy at the limit of perception. At 150x the galaxy appeared as faint, elongated, thin glow. North of the galaxy an apparent field star.

MODERATE
8" f/6, 100x, Bortle 4
Relatively easily seen as very faint, elongated & thin brightening with averted vision. Just an evenly bright glow. Nearby an interfering 10.16 mag star. Faint 13.15 mag star inside the nothern extension. Bright NGC2537 (Bear Paw) 17' northwest.
MODERATE

NGC2424 (GLX)

Coordinates: 07h40m39.32s / +39°14'00.30"
Brightness / Size: 12m6 / 3.6x0.5'
8" f/6, 133x, Bortle 4
Small, slightly elongated, faint.

NGC2826 (GLX)

../dss/dss2blue_091924.19_+333726.06_5_web.jpg
Image source: DSS II (blue) - 5×5'
Name: NGC2826, UGC4939
Type: GLX
Constellation: Lyn
Coordinates: 09h19m24.19s / +33°37'26.06"
Brightness / Size: 13m6 / 1.6x0.3'
8" f/6, 150x, Bortle 5
Elongated, evenly bright, tapering endings. Held with averted vision fairly well.

UGC3445 (GLX)

../dss/dss2blue_062132.76_+590736.07_5_web.jpg
Image source: DSS II (blue) - 5×5'
Name: UGC3445
Type: GLX
Constellation: Lyn
Coordinates: 06h21m32.76s / +59°07'36.07"
Brightness / Size: 12m4 / 1.5x0.3'
Worthwile! Together with UGC3446 an enexpectedly bright pair of galaxies. Both galaxies fairly easily seen with 8 inch, even under a suburban sky.

4.5" f/8, 100x, Bortle 4, NELM 6.0
Roundish, diffuse. Slightly brighter than UGC3446. Fairly easily held with averted vision.

8" f/6, 171x, Bortle 7, NELM 4.5
Quite small, faint, diffuse, roundish brightening. Appeared a bit brighter than UGC3446.

8" f/6, 100x, Bortle 4
Both galaxies (UGC3445 & UGC3446) already seen at 37x as faint, slightly elongated brightening with averted vision. At 100x nicly separated from UGC3446, roundish with obviously brighter core area. No elongation seen.
