Coma cluster (ABELL 1656)

Perhaps not the most visually stunning image in my gallery but perhaps the most interesting.....

The Coma cluster (ABELL 1656) contains over 1000 galaxies and is dominated by two elliptical galaxies NGC 4874 and NGC 4889. It was also one of the first places where gravitational anomalies were observed by Fritz Zwicky in the 1930s’s, today it is thought that 90% of the cluster mass is formed of Dark Matter.   

A strange looking object is the star HD 112886 (top, middle).  Is this an optical illusion created by a much nearer star and a “needle” type distant galaxy which appear to be overlaid on top of one another ?

Taken with a Trius SX 26C. LIGHTS: 25 x 600s; DARKS: 40; BIAS:100; FLATS:40 all at -20C.
