NGC891 #2, I think

This is just a sketch with only 8 sub exposures.  It would look much better with 5 times as many, even though it would still be tiny.

There are four other galaxies in this image, all in the lower right quadrant, NGC898, NGC906, NGC909, and NGC910. Exercise for the viewer. 🙂

[Edit] Not #2.  I was thinking of NGC4565, a similar galaxy.
