M 75 GC, a small giant cluster of the region

M75 or NGC 6864 is an incredible globular cluster when seen by the Hubble Telescope, it is consider a giant cluster. The Hubble image you can appreciate following the next link https://en.wikipedia.org/wiki/Messier_75#/media/File:Crowded_cluster_Messier_75.jpg

However it is quite small to capture from the backyard with a moderate telescope.
Despite of that, it is still possible to enjoy its complexity.

The image was capture on two night sessions, one of 20x120 seconds and another of 40x120 seconds.
For the colours, regarding the stars, I am relying on PxI Photometric calibration tool.

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.
