The Coma Cluster (Abell 1656) is a collection of galaxies (more then 1000 identified galaxies) located in constellation Coma Berenices. The brightest member in the central region of the Coma Cluster is Coma B (NGC4889 or C35) and about 300 million ly away from Earth.

Using Astrometry.net about 100 galaxies can be seen on the picture (both NGC and IC)

Setting : TLAPO80/480 f/6 with ASI2600MC, guidingscope 30/120 with ASI224MC

Light : 12x300s, darks, bias, flats and darkflats
