Description

NGC7331 (also known as Caldwell 30) is a spiral galaxy about 40 mega light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel in 1784. NGC7331 is the brightest member of the NGC7331 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.

Observation Notes : Bright, large, very elongated, much brighter in the middle with a stellar nucleus at 135X. It is an elongated shape even in the 11 X 80 finder. It is surrounded by companion galaxies.
