It's hard to believe this our first image on four months from California. And, of course, it was near full moon. So when the moon throws light at us it's time for a star cluster!

Processing was very simple:

Lum:
DBE
blurxterminator

RGB:
channel combination
dbe
blurxterminator
spcc
ghs
LRGBCombination (to add in L)
unsharp mask (very very mild)

The really unusual thing here is I didn't stretch the luminance. We use 900s luminance files and the main stars were already bright enough. Also the GHS stretch on the RGB was very mild. Because of the very mild (and for L non-existent) stretches no noise reduction was needed.

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.
