Description

A subtle dwarf spiral galaxy in Ursa Major that doesn't seem to get a lot of attention.

Also... an experiment going unguided with NINA's built-in dithering - no PHD2.  Trying to see if there's less vignetting without the ZWO large OAG and I was seeing some stray light that was worrying me looking like a cracked corrector plate on the edge (of the Edge). Turns out it probably was a combo of the Celestron hard shell dew shield that has a corner open gap for cables combined with vignetting exaggerating stray light - phew!

BTW, very impressed with NINA's dithering without PHD2. Since I was running 2350mm unguided, I took 1 minute exposures for the stars and 3 minutes for the nebula. Idea was that I could put the 'cleaner' stars in with the better exposure of the nebula.
