Composite image of the NGC 7331 group of galaxies in Pegasus, which is also known as the Deer Lick group about 46,000 LY away.

The main galaxy is about the size of our own Milky Way and around 10th magnitude, with several fainter ones in the same grouping.

This a composite of some 10 separate images taken over several years with a C-11 and C-14 HD at f/7.

Cumulative exposure time was about 40 minutes at ISO 800-3200.

NGC 7331

"NGC 7331 (also known as Caldwell 30) is a spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel in 1784. NGC 7331 is the brightest member of the NGC 7331 Group of galaxies.

The galaxy is similar in size and structure to the galaxy we inhabit, and is often referred to as "the Milky Way's twin", although recent discoveries regarding the structure of the Milky Way may call this similarity into doubt."
