Object name: ABELL1656
While I'd taken some of the spiral galaxies that hover around the edges of the Coma Cluster of galaxies, ABELL 1656, I'd not taken the center of it which is mostly S0 and elliptical galaxies. My field of view isn't sufficient to begin to cover the cluster. NED lists it as having a diameter of 5.33 degrees. I'd need over 100 images to cover it all. Fortunately, it is highly concentrated so I get a lot of its members by taking the center. NED lists it as having 484 members which is a severe understatement as there are over 1000 galaxies in my image alone with redshift data. Far too many for me to even think about annotating. I settled on just listing those in the IC and NGC catalogs plus a couple PGC galaxies about as big and bright as the NGC and IC galaxies. The cluster has two main cD type galaxies that are huge and thus anchor gravitationally the cluster's vast members. The normally sized galaxies look like moths swarming around two lights being small in comparison to these two monsters. The cluster is listed with a redshift that puts it 330 million light-years distant. At first, I wasn't going to include distance figures for these since they all are about this distance. But due to their orbiting the barycenter of the cluster which is rather massive they can have rather high velocities toward or away from us. Also listed in parenthesis is the non-redshift distances which usually stick much closer to the 330 million light-year distance than does the redshift values. Comparing the two seemed interesting so I decided to include these distance estimates.
