This is a standard SHO (Hubble Palette) image. I experimented with different ways to combine SHO but found that the simple channel combination of Sii in Red, Ha in Green and Oiii in Blue was the most pleasing to me. I have been refining my NB workflow as follows:
Dynamic Crop and DBE to individual masters
Channel combination
Another application of DBE
SCNR
Make synthetic luminance from individual masters
Combine synthetic luminance with SHO image using LRGB Combine
Apply Noise X
Create Starless Image and Stars with Star X
Another application of Noise X on Starless image
Process Starless image - LHE, MNT Sharpening, HT and Curves, Color Masks
Darkened stars a little with HT
Combined Starless and Stars

This workflow seemed to give me more control over colors - at least it gave me the colors I was looking for but I undoubtedly will fiddle around with this some more.

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.
