Abell 2151 Galaxy Cluster in Hercules

Here we have Abell 2151 also known as The Hercules Cluster. This is an interesting agglomeration of as many as 200 galaxies located about 500 million light years away. This is part of the Hercules Super Cluster which is a part of the Great Wall Super Structure.

These are truly amazing if one considers how much there is in the 0.8 degree FOV. This one is also of interest because it contains no giant elliptical galaxies which are generally present in cluster like this. But it does contain a lot of varying galaxy types and a lot of interacting galaxies. One can even see a pair that looks quite similar to the Butterfly Galaxies or Siamese Twins.

I did this work under a bright moon and as a consequence, I did have to work with some pretty strong gradients. But I am somewhat pleased with the outcome.

This project will likely mark the end of galaxy season for me,

I hope you like it... clear skies!!

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.
