Description

A wide-field image of the Coma-Virgo Galaxy Cluster including the Messier galaxies around the star 6 Comae at top right, down to the galaxies of Markarian’s Chain at bottom left, including several other Messiers. The field is about 4 degrees high and 6 degrees wide.

This is a stack of 5 x 8-minute exposures through the SharpStar 76mm EDPH refractor and with the SharpStar flattener/reducer for f/4.5, and with the Canon EOS Ra at ISO 800. An additional exposure taken through light cloud layered in added the star glows. Clouds prevented more exposures.
