Stephen's Quintette is one of the most famous compact galaxy groups. It consists of 5 galaxies several of which are interacting. The 5 galaxies are (from right to left) NGC 7317, NGC 7318A, NGC 7318B, NGC 7319, and NGC 7320. All of the galaxies are around 13th magnitude, and not difficult in a 10" under moderately dark skies. The group is situated in northern Pegasus, about 1 degree south-west of the bright galaxy NGC 7331. There are a number of fainter galaxies visible in the image. The brightest is the 16th magnitude NGC 7320c, a short distance to the left of the group.
