A Study of Messier Globular Clusters - Part 3 - Messier 4 and Antares

This is the one image in the series so far shot with the small refractor. This is a very difficult target in the light-polluted Dallas skies.

7,200ly, 70,000 stars, 75ly in diameter, 12.2byo (but with some stars as old as 13by)

Description: My original image here really was a piece of dog crap. But SPCC, NXT, and BXT allowed me to pick up that turd by the clean end and polish it a bit. What I did to this image is illegal in 37 states. And it still tastes a bit rancid, but with a stiff rum chaser, I was able to choke it down. I've never had even remotely good conditions to try to capture anything near Rho. But God willing and the creek don't rise, I'll take the new Tak somewhere in the RV this spring and grab this thing.

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.
