I turned my RC-8 to this nebula back in May thinking this would be a nice narrowband object. Unfortunately I didn't realize how many subs an f8 scope would require to produce SII and OII masters with an acceptable SNR. I tried combining the linear images in Pixinsight but the Ha simply overwhelmed everything else and reducing the green cast dimmed the image too much. So I borrowed J-P Metsavainio technique and stretched and removed the stars from each channel before combining them. Somewhat labour intensive but I was much happier with the results. After many tries I added some stars I shot in RGB. Your feedback and suggestions are most welcome.
I reprocessed the masters with MureDenoise and used Starnet2 to make starless versions and star masks in this new version. I then used a few techniques that I picked up from Adam Blocks videos. I prefer the colour in this version. What do you think?

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.
