- Thin Galaxies (And) -

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.

FAILED
70mm f/5.7, 26x, Bortle 4-, SQM-L 20.9
Elongated, thin, tapering endings, rather evenly bright. Rather well seen with averted vision.

MODERATE
80mm f/6.25, 33x, Bortle 3, SQM-L 21.3
Very elongated, evenly bright, getting a bit wider toward the middle with tapering endings.

MODERATE
4.5" f/8, 28x, Bortle 4, NELM 6m0+, SQM-L 21.1
Thin, very elongated, somewhat brighter and broader toward the center, otherwise rather evenly bright. Fairly well seen with averted vision.

MODERATE
120mm f/5, 75x, Bortle 6-, NELM 4m8+, SQM-L 19.1
Only the brighter core area was visible as rather faint, elongated brightening.

MODERATE
120mm f/5, 18x, Bortle 4, SQM-L 21.1
At 18x rather faint, very elongated with tapering ends. At 40x similar view but overall more obvious. The dust lane was not visible.

MODERATE
120mm f/5, 18x, Bortle 3, SQM-L 21.3
At 18x more or less obvious with averted vision, elongated, evenly bright. At 75x the dust lane is perceptible to some extent with averted vision, but not clearly & permanently visible.

MODERATE
152mm f/5.9, 100x, Bortle 6, SQM-L 19.3

FAILED
152mm f/5.9, 72x, Bortle 4, SQM-L 21.2
At 34x evident with averted vision, evenly bright, very elongated with tapering endings. At 72x and 100x the dust lane is well visible with averted vision.

EASY
8" f/6, 66x, Bortle 6+, NELM 5m0+, SQM-L 19.6
With averted vision very elongated, evenly bright, tapering ends, slight broadening toward the middle. Overall pretty faint and anything but conspicuous.

MODERATE
8" f/6, 100x, Bortle 4, NELM 6m0+, SQM-L 21.1
One of the most beautiful edge-on galaxies of the autumn sky! Already seen at 37x as faint, very elongated and thin nebula with averted vision. Can easily been overlooked. Broadening and slight brightening toward the middle. At 100x dust lane obvious with averted vision, which is slightly shifted to SE. The surrounding area of NGC891 offers many more interesting galaxies, particularly the galaxy cluster Abell 347!

B 16x70, SQM-L 21.5
wie von Geisterhand erzeugt erscheint indirekt ein länglicher NO-SW-elongierter Nebelschimmer - die Aufhellung wirkt leicht bauchig - schwer, aber nicht grenzwertig

DIFFICULT
B 18x70, SQM-L 21.5
mit ein bisschen Geduld wir indirekt ein blasser, länglicher Schimmer sichtbar - homogen hell

DIFFICULT
100mm f/6.4, 71x, SQM-L 21.5
bei 32x ist die Galaxie indirekt mit NO-SW-Elongation erkennbar und kann mitunter länger gehalten werden - bei 71x ist sie indirekt einfach und zeigt sich 4:1 elongiert - an der Nordflanke ist ein Vordergrundstern erkennbar

MODERATE
12.5" f/4.5, 111x, SQM-L 21.5
bei 45x ist ein heller länglicher und diffuser Nebelstreif erkennbar - die Sichtbarkeit verbessert sich bei 111x und das Staubband ist indirekt sichtbar und weit durchgezogen, Elongation 4:1
