PGC 8961 (with PGC 8970 = Arp 273)
A 13th-(B)magnitude spiral galaxy (type SA(s)b pec) in Andromeda (RA 02 21 28.7, Dec +39 22 32)
PGC 8961 and 8970 form an interacting pair of spiral galaxies, also known as Arp 273. Both galaxies are considerably distorted by their interaction, but PGC 8961's spectacular arms and brilliant clouds of hot, bright young stars caused by the interaction are more obvious because it is nearly face-on to our line of sight; while PGC 8970's form is more edge-on, and appears more a chaotic mess than its companion. Based on a recessional velocity of 7565 km/sec, PGC 8961 is about 350 million light years away. Given that and its apparent size of 2.2 by 1.4 arcmin, it is about 225 thousand light years across. This makes it more than twice the diameter and about ten times the volume (and most likely, mass) of our Milky Way galaxy.

It's definitely a spiral galaxy, nebulae don't usually have such long spiraling structures.
I've tracked it down using Stellarium and Sky-Map.com
It's a galaxy called PGC 8961 ( Sky-Map link) in the constellation Andromeda. You can see it interacting gravitationally with a smaller galaxy PGC 8970.
Here's a cool photo of both of them:
Galaxies appearing in photos of comets is nothing new or incredible, but it does make for great photos

Good work identifying it. And you're absolutely right about such things making for beautiful images. No question about that....
