M3 Globular Cluster a Target of Opportunity LRGB

A target of opportunity. I had gone to setup to capture the eagle nebula when both of my weather apps and google said clear skies and no wind. We all know what happened next, I had 90% cloud cover. The only part of the sky that clear was to the west. Thankfully the M3 globular cluster just happened to be in that pocket of sky. I had wanted to try my hand at another globular cluster after capturing M13 earlier this year.

A quick image with not much exposure time and a fair amount of noise, but still fun to see my progress from M13. Also, another Messier object to check off the list.

M3 is a globular cluster that sits 33,000 light years above the plane of the Milky Way Galaxy approximately 34,000 light years away. It’s approximately 360 light years in diameter and is estimated to contain 500k stars. The cluster has an age of approximately 8 billion years with predominant long lived red stars that are less than our solar mass. The large blue stars are named blue stragglers as all of the original high mass blue stars have exhausted their hydrogen fusion supply and gone supernova with remnant white dwarf stars or possibly low mass black holes. The blue stragglers in the image are possibly younger stars than the rest of the cluster and form from a rare event with the merger of smaller mass stars.

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.
