This is NGC 6823 in SHO with RGB stars though I don't think the RGB really add much when the image is border-to-border nebulosity, but we wasted a bunch of time acquiring them (probably 2-3 times what we needed) so I included them!

Processing was fairly typical for what I've been doing to emission nebulae lately:

Each S, H and O master:
blurXterminator
starXterminator
noiseXterminator
GHS (GH, linear, GH)

RGB:
channel combination (RGB)
GH (stretching for stars)
starXterminator extracting unscreened stars)

stars:
unsharp mask (very mild sharpening)

SHO:
channel combination (SHO)
histogram transform to align peaks
SCNR to remove the prevalent green hydrogen cast - 70 minimum neutral)
LHE (2 scales.- 75 and 30, both masked)
Curves (color - masked)
Curves (contrast)
Dark Structure Enhance script
pixel math in stars
(no MLT sharpening as the small scale LHE seemed to have enough of a sharpening-like effect - perhaps borderline too much)

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.
