Stephan's Quintet

||||||||||
|
Stephan's Quintet: This galaxy cluster located in the constellation Pegasus, just a nudge from NGC 7331 is comprised of three eliptical galaxies, one spiral bar and one non-barred spiral. Its members labeled below are about 300 million light years distant, with the exception of NGC 7320, which is 40 million light years away but visually appears connected with the group. This is a tough visual target even for large aperture scopes as its members range from magnitude 12.6 (NGC 7320) down to magnitude 13.6.
NGC 7320c is not considered to be one of the Quintet, but made it in the image Field of View.
