The region around Abell 1656, the Coma Cluster of Galaxies, in Coma Berenices.
A map of the region is shown below, and beneath that a second map, showing the core of the cluster.
This image is a stack of 12 eight minute exposures using an STL11000M CCD camera through a Tele Vue NP127is 5" f/5.2 apochromatic refractor.
The image was calibrated, defect corrected, stacked and gradient corrected,
then a Sigmoid Scaling was performed, all using AIP4WIN V2.
This image has been resampled down from its original size of 3981x2655.
Clicking on either the image above or the map below will display an enlarged view.
The map was created using MegaStar.
