NGC 6255, Distant Galaxy Clusters and a Far-away Quasar

Revision title: Re-processed

NGC 6255 is a rarely imaged galaxy. The blue object near the left edge is actually another galaxy HS 1653+3634 according to SIMBAD.

[SPD2011] 52385 galaxy cluster near the center of the image is has a redshift 0.347, so the distance is about 3.9 billion light years.
NSC J165601+363031 cluster on the left is 2.5 billion light years away (redshift 0.206).

There is a very distant quasar with redshift 5.15 in the top right area of the image (please see the annotated revision B). The light from this quasar has traveled 12.5 billion years!

Thanks for looking.

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.
