"The Flying Bat and the Blue Squid" (HOO) imaged in OSC Dual Narrowband

Sh2-129 and OU4 or "The Flying Bat and the Blue Squid" are a fascinating object and there are many great images of it here on AB. However, as it turns out, it is not that straight forward to process when shot with an OSC and a dual narrowband filter. I had been struggling quite a bit at the beginning as it is not sufficient to just use the green channel as a proxy for OIII. Luckily I got great help in this forum discussion . Thanks again to all that contributed.
So this is the version I ended up with, pushing the limits of my processing abilities.
While it is a substantial amount of data, a lot has been shot in suboptimal conditions with moon or around the summer solstice, so unfortunately only a small portion is of good quality. I will try to add more data in the future, ideally some of it shot with a single line OIII filter to circumvent some of the processing issues.

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.
