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.
