NGC7320 and Stephan's Quintet
Just to the SW of NGC7331 is a group of 5 galaxies named Stephan's Quintet. The brightest, NGC7320 (centre of image above), is visible in moderate amateur scopes, but large scopes are needed to resolve all five. Four of the galaxies are linked, but there is some doubt as to whether NGC7320 is actually a true member.
