Description

Another image using data from my 2021 unprocessed raw image data vault. I finally got around to processing it!

A rich field of interesting distant galaxies. Most of the faint objects in this field in Hercules are galaxies - there are definitely way more galaxies than stars!

I looked at SIMBAD and NASA NED data on 23 galaxies in the field for which data was available, pretty much all the brighter ones. Almost all of them (including IC 1264) appear to be about 136 to 141 mega parsecs away (about 450 million light years) centered around the big elliptical galaxy IC 1262 at 137.55 mega parsecs. This puts the cluster's depth at roughly 16 million light years, while its breadth mostly fits within the 2.2 by 3.4 million light year "field of view" of the image for a cluster that is 450 million light years away from us. 

The pretty barred spiral IC 1263 and little PGC 60485 may not really be a cluster members, as they about 50 million light years closer and farther away, respectively, than all the other cluster members.

The rest of the really tiny faint blurry smudges are anonymous, unnamed galaxies well over 2 billion light years away, and maybe as far as 3. Some vital statistics on the larger, brighter objects.
