Abel 1656 The Coma Cluster in mono

The Coma Cluster is a large cluster of galaxies that contain over 1000 identified galaxies and in this image approx 200 can be identified down to mag 20.0. Along with the Leo Cluster it is one of the two major clusters comprising Coma Berenices. The clusters mean distance from earth is 321 million light years. Most of the galaxies are elliptical and the 10 brightest spiral galaxies have apparent magnitudes of 12-14. The central region is dominated by 2 supergiant elliptical galaxies NGC 4874 and NGC 4889. These things are very hard to get ones head round.
With no astronomical darkness at the time this image was taken and the relatively short exposure time I am surprised at the result. It would look better in colour but my OSC camera is being returned, as was a previous one because of grease on the sensor.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
