Galaxy Clusters Abell 2197 & 2199 - part of the Hercules supercluster

This image is on the first couple of sights pretty unspectacular, just a decent number of foreground stars. But if one browses throught the background, a fair number of pretty faint (at at best barely resolved) galaxies become visible. They are all at a distance of some 400 Million light years and form the pair of galaxy clusters Abell 2197 and Abell 2199, each of them hosting some 80 galaxies. and this pair is part of a much larger (but dynamically not relaxed) structure - the Hercules Supercluster (SCl 160). The Hercules supercluster and its neighbor - the Coma supercluster are part of the so-called Great Wall. First identified in the 1980s by Margaret Geller, John Huchra and co. The great wall is the prototype of the filamentary structure of the galaxy distribution on the largest scales - the so-called cosmic web. The picture here was done with my small travel rig, a 72mm refractor on a small goto mount. A pretty deep and detailed view for such a small scope, I think

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.
