Abell 2065: Corona Borealis Galaxy Cluster

Abell 2065 is a galaxy cluster in the constellation Corona Borealis that lies at an enormous distance of about 1 billion light years. Among its 400 or so galaxies, its brightest members are of 16th magnitude. Abell 2065 is a challenging subject to image and process; it benefits from a very good dark site, a low-noise camera, and lots of aperture. I tried imaging it two years ago with disappointing results, but this attempt produced a much better result due to improved equipment and processing.

For those of you who like to compare images to star charts, please note that this image is flipped north-south. My capture and stacking software both automatically flip the raw fits files (but why?), and I did not catch it on this one before uploading.

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.
