Re: Two unusual galaxies

Nice work Gregg. You and Dan seem to be in a contest to see who can image the smallest galaxy 😊
UGC 6446 and NGC 3658 are two galaxies about 30 arcminutes apart, just below the bowl of the Big Dipper. UGC 6446 is a low surface brightness irregular galaxy (that appears spiral-like to me). NGC 3656 (on the right side of this image) is also Arp 155, cataloged as "disturbed with interior absorption". It's companion is magnitude 15 MCG+9-19-64 just a couple of arcminutes to the east:
