Messier 56

Messier 56 isn't as well known as M3/M5/M13 are, but I do think it deserves more attention. It's suspected to have been captured from the erstwhile dwarf galaxy, whose suspected remaining core is the spectacular Omega Cluster, and is now part of so-called Gaia Sausage star stream(for real!).

This target was tempting me for a long time and once @Uwe Deutermann, currently on his Messier object hunt, offered some data from his fine FLT132 there was no going back! Uwe was a bit concerned about having shot 300s-long luminance for this cluster but it turned out just fine. I added more LRGB data over the last couple of nights and combined it to produce this close look at the cluster.

The FoV was dictated by my new "narrow field" ASI 533MM camera I've just acquired for my second rig - RC8 telescope mounted on ZWO AM3 - and I think it's just right for smaller objects.

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.
