Great picture. I like the visibility of the weak stuff.  I know how difficult it is to pull up and separate from the background.

Thanks. Managed to pull out far more than my original processing of this data. Combination of new to me techniques and experience since then.

What do you reckon made the most difference?

Far better stretching methods. I separated the stars using ScreenStars and stretched the nebulosity and stars separately.

I used other processes such as BlurXterminator and NarrowbandNormalization.

These were the original images 4 years ago.

@Rattler.  Now I’m seeing there in your two versions exactly what I’m seeing in my recent attempts at processing a wide-field image of the Cygnus Loop. On the one hand I like the delicate detail I see in your original images. On the other hand it’s good to see the bolder, far more colourful and impactful aspects of your more recent version.  I seem to have the same ‘issue’ and am finding it difficult to balance those two extremes.  I guess I just have to accept a compromise. Maybe I can’t have delicate detail and impactful in the same image!

Yeah, I know exactly what you are saying. Overall, I do prefer the recent images but there are aspects of the original that I prefer.
