NGC 6752 The Great Peacock Globular Cluster in Pavo In RGB

NGC 6752, nicknamed the Great Peacock Globular is a globular cluster in the constellation Pavo. Also known as the Starfish or the Windmill Cluster. It is the fourth-brightest globular cluster in the sky, after Omega Centauri, 47 Tucanae and Messier 22, respectively. With an apparent magnitude of 5.4, so it can be seen with the unaided eye and with binoculars it can be seen to cover an area three quarters the size of the full moon. It has a core region densely populated with stars around 1.3 light-years in diameter and lies around 13,000 light-years away and is one of the closer globular clusters to Earth and lies 17,000 light-years away from the galactic centre. It has a calculated age of 11.78 billion years. There are many binary stars in the system, as well as blue stragglers, which are likely to have been formed by collisions and mergers of smaller stars.

An extraordinary night that started with cloud and scud and ended clear with very, very good seeing. Once it settled down the auto-guider rarely flickered past .5 of an arc-second. I am really enjoying imaging globular clusters, moon permitting, because they allow shorter exposures and that means a lot more subs in less time.
So much easier to hack off the dead wood in sub-frame selector.

Updated 5th Sep 2022
Some more work on reducing background light pollution and noise. Of all the globular cluster I have been lucky enough to image lately, I think this one is the prettiest.

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.
