The five brightest galaxies in the center form what is known as Stephans Quintet. The main galaxies range in brightness from 13.1 to 14.3, and the largest NGC7320 is 2.3'x1.1' in size. The main group of three in the center are extremely tidaly distorted and are classed as peculiar, clockwise from the top we have NGC7319, NGC7318b, NGC7318a, and NGC7320 on the bottom. Off to the lower right is NGC7317. Off to the right is NGC7320c, a 16.7 magnitude ring galaxy spiral. The photographic limiting magnitude of this shot is near 20.
