The Hydra Cluster | Abell 1060 | LHaRGB

The Hydra Cluster (or Abell 1060) is a galaxy cluster that contains 157 bright galaxies, appearing in the constellation Hydra. The cluster spans about ten million light years and has an unusually high proportion of dark matter. The cluster is part of the Hydra-Centaurus Supercluster located 158 million light years from earth. The cluster's largest galaxies are elliptical galaxies NGC 3309 and NGC 3311 and the spiral galaxy NGC 3312 all having a diameter of about 150,000 light years. [thank you Wiki]

 

This image was compiled from five colour filters, of luminance, red, green, blue, and hydrogen alpha. Hydrogen alpha was used to help define NGC3312, and many of the other galaxies.

 

The size of the approximate central, colourful galaxy, NGC3312, is only 3.3 arcminutes.

 

Hope you enjoy having a look, as there are a crazy number and varying types of galaxies to see.
