Ngc3842/ Abell 1367 - the Leo galaxy cluster

Abell 1367, also known as the Leo Cluster, is one of the richest of the nearby galaxy clusters however its brightest galaxies are spread randomly throughout its extent with many sub concentrations. Given the cluster diameter is about 100 arcminutes (so three the diameter of the full moon) this means you have to scan across the field to find all the sub-concentrations.
Abell 1367 in Leo is often overlooked which is disappointing as there are 21 NGC galaxies in this field and with larger telescopes you can see up to 20 galaxies in the same eyepiece field.
The cluster does appear to have a higher ratio of spiral to elliptical galaxies than most clusters and as such is believed to have formed relatively recently as one would have expected the spiral galaxies to be destroyed by mergers and interactions over time. Indeed a number of the spiral galaxies appear to show tails in the radio which suggests matter being stripped out as they plunge through the intra cluster gas.
Abell 1367 together with Abell 1656 form the Coma super cluster which is the closest supercluster to the Virgo cluster of which our Local Group is a part. Both of these clusters along with the Hercules cluster appear to be part of a group of galaxies dubbed the Great Wall.

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.
