M4 in Scorpius

Messier 4 located in one of my favorite parts of the sky within the Ophiucus Cloud complex. I think not too many folks image this alone simply because of all the other very interesting and beautiful objects that are all in close proximity.

This loosely concentrated globular has an estimated age of 12.2 to 13 billion years and lies approximately 7,200 ly away. There is evidence of at least 2 different stellar populations within this cluster which would mean there were multiple cycles of star formation.

Of particular interest to me is that in 2003, a large planet about 2.5 Jupiters in mass was discovered orbiting a binary system containing a white dwarf and a pulsar. One could only imagine the view of this system.

The information above was obtained from messier-objects.com.

Not the easiest to process for some reason. I had some strange issues with calibration files. I went with a bias toward the red because of the general morphology of this area.

Comments and criticism always welcome and Clear Skies to everyone!

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.
