Phew, I knew this target was dim, but I was still surprised at how little I could see on the raw subs. Basically just a hint og NGC 4889.

But I am reasonably happy with the amount of galaxies that showed up in the final processed image. I conservatively count 311 galaxies (rev C), but I a sure many of the tiny fuzzies also seen are more galaxies. There are supposed to be over 800 of them in this group!

So even if it is a bit noisy, it was fun to shoot and process this one, though I may leave more galaxy clusters like this to people with larger telescopes and mono cameras for the time being!

Title: Starless version

Description: Not all the galaxies are shown here, as the star removal was not perfect, and some of the smaller, rounder galaxies got removed as well.

Title: Counting Galaxies

Description: I count 311 galaxies. There are surely more - some of the very small fuzzy dots are likely also galaxies...

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.
