caught faint NGC 3184 (Halifax)

NGC 3184 had been in the queue for a while. The BGO robot collected photons for me. A very faint face-on galaxy in Ursa Major. Another RASC Finest NGC. It appears a classic spiral. Quite lovely with arms subdividing. 

RASC Finest galaxy NGC 3184 in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left.

Collimation is off sadly.

NGC 3184 is also known as MCG 7-21-37 and PGC 30087.

Within one of the spiral arms is a bright diffuse nebula. It has been given it's own catalogue number: NGC 3181. This is south-west of centre.

GSC 03004-0280 is north-west of the galaxy and it looks like a classic double. Slightly unequal stars. A pleasing separation. But SkyTools 3 Pro does not show that they are related.

The little triangle of faint stars, with J101751.4+412511, is tantalising. ST3P says they are unrelated.

GSC 03004-0523 to the south-south-west is similar. Unequal stars. Very close together. But ST3P indicates they are unrelated.

LEDA 2181848 is a small oval fuzzy north-east of the spiral.

LEDA 2183464, a fuzzy oval, is above the stars GSC 03004-0525 and TYC 03004-0823 1.
