2h 20min of integral Ha exposure of M12 globular cluster - captured remotely Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope observatory, over 2 imaging sessions carried out on Sep 3, 8, 12, 2023.

A pair of interacting galaxies (one of which is identified as PGC 1103219) is visible in the lower right corner with hints of what might be an extended arc stretching to the upper left corner of this cropped image (150% of original scale):

Another galaxy identified as LEDA 3872365 [2] is also visible here closer to the M12 (marked by red dashed circle in the image below):

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.
