Rendezvous between M3 globular star cluster & Comet Leonard

In the very early morning of December 3rd, Comet Leonard passed by the globular star cluster M3 in Canes Venatici. At least it looked like that from the earth's perspective even though the separation between them was some 33.900 light years. I was lucky to get 45 minutes of clear sky perfectly timed to see the cluster touching a bit the comet's afterburner (or tail, as they call it).

The rendezvous was captured with two telescopes running in tandem to collect color data in the smallest scope and luminance data through the larger one. The total data set was INSANLY difficult to process as it required four differenet stacks, separating the stars (with the tricky cluster) and the comet in both color and mono versions.

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.
