Stephan's Quintet is located in the constellation of Pegasus and was discovered in 1876 by Edouard Stephan using a 80cm reflector. Originally, he perceived the close pair (NGC 7318 A/B) as a single galaxy, so originally it was perceived as a quartet. One of the galaxies (NGC 7320) is actually much closer to Earth (45m light years) than the rest which are much further away (287m to 310m light years).
I thought a good challenge to have a go at the object since a search revealed that their are relatively few amateur images, probably because it is so tiny. The resultant LRGB image represents just over 12hours integration and was taken with my Esprit 150. .
