7331 and The Deer Lick Group,
The large spiral galaxy is NGC 7331 and the smaller
one above and to the left is NGC 7337, the one above and slightly to the right
is NGC 7335. Just to the right of 7335 is NGC 7336. 7331 measures about 11 x 4
arcmin. I have no idea why the groups is called "the deer lick
group." North is to the right in this image.
