- Thin Galaxies (Leo) -

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.

Extremely thin, very elongated, evenly bright. Seems a little bit harder than UGC3697 (Integral Sign Galaxy).
DIFFICULT

bei 72x ist die Superthin indirekt gut definiert erkennbar - Elongation NO-SW 4:1 - bei 111x wirkt das Zentrum heller und ebenfalls in die Länge gezogen - bei 160x wirkt die Spindel etwas breiter
EASY
