Abell 1656 - The Coma Cluster

The Coma Cluster, located near the north galactic pole, contains over a thousand galaxies. I have not counted, but there seems to be about that many in this photo. You have to view full screen to really appreciate this area of the sky. It's quite difficult to tell which dots are stars and which are elliptical galaxies.

Stacking, gradient removal, and color calibration in Siril, but no Starnet++ on this image. I'm not sure what is a star and what is a galaxy, so not sure if the model would be able to tell either. Denoising with Topaz, then some very minor Photoshop adjustments.

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.
