Default ASTRO: NGC 7331 with galaxies ID'ed

This is one of the most confusing areas of the sky if you are interested in
what we humans name things. Many of the NGC objects in this area are not
galaxies at all, but just double stars picked up by Temple in the 19th
Century. The RNGC and other listings have compounded the errors over the
years. The NGC-IC Project (http://www.ngcic.org/) has tried to figure this
all out by referring to the original sources but Temple is very vague. The
ID's for the "stars"are just a current best guess. The "real" galaxies are
in bold-black, while the "stars" in the NGC are gray-underline in the
attached image. The little 18+ mag galaxy is sometimes listed as on of these
NGC objects, but I know I can't see 18.5 mag in a 9 inch telescope - in fact
I can't see that galaxy in a 20 inch. The MGC galaxy could just possibly be
one, but the location is wrong.
