This object is a large 400 member galaxy cluster located 1 billion light years away in the constellation of Corona Borealis at a declination of +28 degrees. Typical of these clusters, the largest and brightest galaxies are the elliptical galaxies in the center of the cluster. These elliptical galaxies are each about 16th magnitude in brightness, 0.7 arc-minutes in width, and 175,000 light years in diameter.

73 PGC galaxies are identified in the mouseover in an image that has a field radius of 0.2 degrees. Many other galaxies are visible but not identified in the mouseover. Several bright 10th magnitude foreground Milky Stars are superimposed over the cluster.

I like the smaller but more elegant spiral galaxies, especially the face-on galaxy near the top of the image (galaxy 2MASX J15221649+2748261). Strange that this galaxy does not have a PGC designation and is not identified in the mouseover. It is 120,000 light years in diameter.

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.
