Lum SNR is 1443. Ha did not work quite well and generated SNR of 50

Processing:
RGB are combined.
Cropping for RGB, Lum and Ha
DBE was applied for RGB, but not Lum and Ha
Color Colib for RGB
Blur and Noise XT for RGB, Lum and Ha
Star XT for RGB, Lum and Ha. RGB stars were saved, while Lum and Ha stars were discarded

Manual stretching (with HT) RGB, Lum, Ha and RGB stars
Created LRGB
Added Ha using Pixel Math.
Noise XT again
Stretching again
Simple Lum mask
Local Histogram Equalization (LHE): Kernel radius of 40, 150 and then 300
Multi-scale-media transform to add sharpness.
Curves: saturation and brightness are manipulated.
Mask off.

RGB-stars masked by Lum copy.
Curves: saturation and brightness of stars are manipulated.
Saturated stars are added to starless nebula.
Done

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.
