Description

NGC 7331, the Deer Lick group, is a collection of galaxies in the constellation Pegasus.  The foreground of this field is occupied by the actual galaxy NGC 7331 with NGC 7335, 7336, 7337 and 7340 occupying the background.  Technically speaking, the Deer Lick group isn’t an actual group of galaxies due to the lack of gravitational interaction between the individual galaxies.  It’s fortunate that the background “fleas” present the way that they do but - the actual distance between individual galaxies is on the order of ~2 million lightyears.  Even so, this region of Pegasus is incredibly rich with galaxy clusters with Stephan’s quintet just out of frame to the bottom left.  An incredibly faint, but slightly resolved, integrated flux nebula can be seen all throughout the foreground of the image, extending all the way from NGC 7331 to Stephan’s quintet.  The naming of this group of galaxies is completely unrelated to physical deer and is instead a reference to the observation of NGC 7331 by Tom Lorenzin one night at the Deerlick Gap Overlook in North Carolina.
