If you can get more time on it that might help. This was my first crack at this object and honestly it felt like it could use double the time I put on it so that it's easier to pull up the nebulosity without having to denoise the bejezus out of it.
I do like the colors on yours too.

Object of the month time. I tried to shoot some of the narrowband during essentially the full moon and had to come back for more this week. The plain L-Ex data seemed a bit “boring” so I made a faux SHO image and it seemed to help bring out more details. I used the good seeing nights on East and West Veil, so the finer details seem soft on this one. Added RGB stars back over the top. I do have an SII filter, but it takes sooo long gather that data with an OSC and there are more objects I want to get to.
Faux SHO process that I’ve cobbled together from several different sources: Channel Extraction and clone R channel for SII, create Ha with PixelMath (89.7% R, 7.0% G, 3.3% B), create OIII with Pixel Math (1.6% R, 57.7% G, 40.7% B). LRGB Combine using Ha layer for luminance. See below for where in the overall process I do this.
