Abell 2666

Abell 2666 is relatively small but rather distant (about 340 million light-years) galaxy cluster located in the constellation Pegasus, about 4 degrees from Alpheratz. In the center of the cluster clearly dominates the giant cD elliptical galaxy NGC 7768.   Wider Abell 2666 field is shown above (north is up) and some more detail view of the central part around NGC 7768 below.
