Late to the party with this one, This was an experiment with SubFrameSelector script in PI, I chose only images that fell within the range. so I kept about 30 of 50 subs for each H and O filters. Subframe Selector was ran after calibration and cosmetic correction. Next, star alignment and integration, followed by drizzle integration was run along with a pass of ABE on each master.

Color combination was done with Pixel math R/K: HA

G: (0.05*HA)+(0.95*OIII) and B: OIII, then LRGB combine was done to combine the H with the bi-color RGB image settings were about default. Then cropped and saved as a TIFF 16bit.

Imported into Light Room were some final color adjustments were made with the HSL sliders, then some Clarity boost, some slight sharpening and noise reduction applied before exporting the image.

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.
