Messier 3 Globular Cluster

Took the opportunity to tick off another Messier object before xmas but had not published due to lack of all the necessary calibration frames.

M3 is a globular cluster situated in the constellation of Canes Venatici some 33,000 light years from my backgarden and is 12 billion years old, so really quite a relic of the universe. It contains stars all along the colour magnitude diagram with the majority in the main sequence stage but also contains some blue stragglers (not evident in my image) - very blue and large. It is said that these blue stragglers should actually have died based on the age of the cluster but one hypothesis is that sets of 2 smaller blue stars have joined to form the larger blue.

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.
