M3 Globular Cluster (2023)

Revision title: 2024 Reprocess

Like a serpent eating its own tail, I'm coming back to the first globular cluster I imaged back in early 2021. In hindsight I wish I'd gathered more time on this, but it's heartening to see the improvement in colour, star-shape and the density of resolved stars. Globulars are such interesting objects to process!

Title: 2024 Reprocess

Description: With the new AI for BlurXterminator, and another year's experience with PI, I wanted to try reprocessing M3 to see I could improve upon my last effort. The core is a bit dimmer this time, but I'm much happier with the individual stars. The rotation has also been adjusted to a more typical view of M3, and the crop is slightly wider so that NGC 5263 is still visible. I have also changed my blackpoint to 24,24,24 as I was finding my images too dark.

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.
