This is NGC 278, a darling little spiral galaxy in Cassiopeia. I first spotted this object while observing NGC 147 and 185, two far-flung satellite galaxies of the Andromeda galaxy located way up in Cassiopeia. While small, the relatively high surface brightness of NGC 278 makes it a fairly easy visual target. I was very surprised to glimpse the outer veil of stars despite the relatively bright moonlight from the rising gibbous moon. Hubble images show NGC 278 as a very tight spiral with a beautiful ring of blue stars surrounding the outer edges of the galaxy.
