M103 Discovered by Pierre Méchain in 1781. M103 is located in the constellation of Cassiopeia at a distance of approximately 8,500 light years. This is the most distant of the Messier open cluster objects. It is comprised of relatively few stars. Harlow Shapley classified M103 as a “loose and poor cluster. The age of the cluster has been placed at approximately 25 million years. The bright red giant, designated WDS BUP 22, is a double star and its brightness and color dominates my image of M103. 1http://www.seds.org/messier/m/m103.html
