Description

Coma Cluster is a dense cluster of galaxies in constellation Coma Berenices. It contains over 1,000 identified galaxies. Along with the Leo Cluster, they make up the Coma Supercluster.

The central region is dominated by two supergiant elliptical galaxies: NGC 4874 and NGC 4889, these can be found in the middle of the photo. The cluster is within a few degrees of the north galactic pole on the sky. Most of the galaxies that inhabit the central portion of the Coma Cluster are ellipticals.

Visual Observation

The ten brightest galaxies are about 11-14 magnitude, though they are quite easy to catch with an amatour telescope. Peter Kiss in the spring of 2015 made an amazingly detailed drawing of Come Cluster. Hava a look at it!
