Abell 2245 - a newly imaged galaxy cluster

I decided to go hunting for galaxy clusters. I wrote a little script to run through the PGC galaxy catalogue and look for areas with lots of galaxies, big enough for me to pick up, in a nice compact field of view. This was the target in the Northern Hemisphere with the largest number of galaxies in my script. It turns out that Abell already spotted this one and gave it catalogue number Abell 2245, although I haven't found any pictures of it.

Unfortunately the weather gods didn't play ball: I've got about 1h30 of rgb taken with my RC8 over a number of nights of high cloud and poor seeing, and the year is pretty much over for this target now. I decided to experiment with buying some remote observing time with skygems, and added in 10x600s Luminance subs (taken under clear dark skies with an expensive Planewave CDK500), and merged them into my rgb subs. So here we have 3h with a mixture of CDK500 and RC8, and a pixel scale of 0.22" / Px. This pixel scale is really pushing things, but there are some interesting shaped galaxies in here. Perhaps next year I'll try to image it again with just my own kit.

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.
