Messier 94- The Cat's Eye Galaxy

The two apparently separated rings give the appearance of a cat's eye, hence the nickname, although the outer rings are very difficult to see visually in all but very large telescopes.

 

Dodging the Moon on this one, but it seemed to work to take luminance first and color after moonrise.
