Coma Cluster, (Abell 1656)

Coma Cluster, (Abell 1656)
A large cluster of galaxies that contains over 1,000 identified galaxies!
It is one of the two major clusters comprising the Coma Supercluster. It is located 321 million light years away in the constellation Coma Berenices.
The central region is dominated by two supergiant elliptical galaxies: NGC 4874 and NGC 4889, center-right in this image, contains one of the most massive black holes known. 5,200 times more massive than the central black hole of the Milky Way.
The diameter of the black hole's immense event horizon is about 20 to 124 billion kilometers.
The Coma Cluster was one of the first places where astronomers observed the effect of dark matter. It is believed that about 90% of the mass of the cluster is a form of dark matter.
The image was taken last februari, from Holland hill observatory, where my telescope lives.
I have exposed the image for 30 hours through LRGB filters to achieve a strong signal of the cluster.
To my delight, the lengthy exposure revealed a very interesting light. The quasar (an extremely luminous active galactic nucleus, powered by a supermassive black hole)
QSO [HB89] 1256+280. This quasar is at a distance of ~11 billion light years! Its light started heading toward us when the universe was only 2 billion years old. It’s really fascinating that it was captured with my amateur equipment, but the image is definitely the deepest of my astrophotography to date.

It took three weeks to collect the material and two months to process the tricky and complicated image.
Hope you enjoy it, I certainly did.

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.
