Picture is of the Coma Cluster, a cluster of Galaxies in Coma Berenices 320 million Light Years away (7 times further away than the Virgo Cluster)and 25 Million Light Years across.
It is one of the densest clusters known and contains over 1000 identified Galaxies, mainly ellipticals.
Practically all objects in the picture are Galaxies but the bright round object upper right of centre is star HD112887. Many of the fainter Galaxies are not part of the cluster but are much further away background objects.
Contains 2hrs of Luminance and 30 mins each of RGB using Atik 460e on 190mm Mak-Newtonian, processed using DSS/PS5/Maxim.
