M_69 (NGC_6637) and NGC_6652 dancing around

Two quite interesting globular clusters from the Sagittarius constellation, NGC 6637 (M69) and NGC 6652, which by the way, is rich in globular clusters.
It is also interesting stretching the image with more than one object with bright centres, and trying to keep the balance. I use an script for colour calibration in PxI, and in some objects I get almost the same colour balance compared with photometric calibration.
According to Wikipedia, there is something interesting regarding M69 and M70, regarding its description by Messier in the search for the objects described by Lacaille, the history is here in wiki:

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.
