NGC7331 in Pegasus is also known as the Deer Lick Group and is around 12 Mpc in distance. The smaller galaxies that appear to group above and behind are almost 10 times more distant and happen to be in our line of sight. We see these galaxies through a faint veil of high latitude dust called galactic cirrus.  See it at APOD
