A Study of Messier Globular Clusters - Part 18 - Messier 80

M80 is one of the more dense globular clusters orbiting our galaxy. It also contains a high number of blue straggler stars--stars that appear to be younger than they should be. Blue stragglers are thought to be the result of the collision and merging of two or more stars in the cluster.

28,000ly, 200,000 stars, 95ly in diameter, 12.54byo

Description: As I close in on completing images of all 110 Messier objects, I want to go back to those I've previously captured and give them another attempt at processing as our tools and my skills have improved. So here's M80 done in that spirit. It's still not great, but I think it is nonetheless greatly improved.

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.
