Galaxy Cluster
| Abell 262 Galaxy Cluster in Andromeda Abell 262 is a galaxy cluster in Andromeda near the border with Triangulum, and is centered on NGC 708, a cluster dominant elliptical galaxy similar to M87. The cluster is part of the Pisces-Perseus supercluster, approximately 205-250 million light years distant. Recent measurements of red shifts indicate that many of the fainter galaxies in the field of view are in fact more distant objects located in a distant background supercluster. The above field of view is centered at RA: 01h 53m 21s Dec: +36d 10' 4", and covers approximately 15 x 24 arc minutes. Date: December 13-16, 2006; LRGB data processed March 1, 2010.
