Taking another attempt at this with the most data I have gotten on this image yet. Really pleased with the final result and the detail I was able to pull.

Processing
- EZProcessing Denoise on both Oiii and Ha
- Ha ArcSin Stretch
- Oiii Linear Fit
- Ha HDR with mask
- Pixelmath combination for HOO
R=R
G=((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~(Oiii*Ha))*Oiii
B=Oiii- StarXterminator star removal
- Color masks to adjust color to desired end state
- Into Photoshop for Astroflatpro
- Photoshop APF-R
- Back to PixInsight for more small detail work with multi scale transforms and range masks
- Back to Photoshop for Topaz Denoise
- Back to PixInsight to recombine stars into Starless
- Back to Photoshop for EZStarShrink

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.
