Version C - Another pass of Local Histogram Equalization with a light mask in an attempt to make the arms stand out a little more. Also, slightly upped the saturation of the dark-redish bands in the center of the galaxy.

Version B - Discarded an hour worth of subs that had elongated stars and reprocessed. This took care of the pixel-rejection artifacts that I got on the stars in the original. Increased saturation on the final pass to bring out more color in the galaxy arms.

Version A - Don't pixel-peep this one. I have some weird artifacts around the stars that is probably due to using some low-quality subs in the stack. I'm probably going to try reprocessing it to address the issue, but thought that this version was worth sharing.

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.
