I had another think about this one and got the star removal to work - ish. It was good enough to let me get more of a stretch into the faint stuff before putting them back.

Outstanding Olly! Stars look great. I usually start with Star XTerminator but if that does not do a good job I have started to use the new version of StarNet2. They are claimed to work according to different principles and sometimes one do a better job than the other. If I cannot decide I make a 50-50 mix.

It is just so sad that the only time this object is above my horizon is around midsummer, so hiding behind an eternally bright sky.

I've noticed they out do each other every time an update comes out.

The "misty morning" reflection nebulosity is beautiful.  Those orangy small stars do detract from the aesthetics a little, sometimes the divine create made life awkward for us.

Thanks for the comment, Martin. I'll have a look at that.

An inspiring target Olly - I wish I had the gear to image it but alas not the case.

I'm with @MartinB with this one - the stars are detracting from the beauty of the nebula.

I've seen this before when putting stars back into an image - whether it be StarX or Starnet that was used for removal.

My experience is it is a whole lot easier to take the stars out than to put them back, irrespective of the method used.

I've tried lots of different approaches most of which result in a very two-dimensional image.

I have found the EZ-SoftStretch script in PI useful for processing the star image and even then it needs 'de-stretching' before recombining with ~((~starless)*(~stars)) in PixelMath.

Failing that I resort to multiple, incremental mini-stretches in HistogramStretch. I am sure there are equivalents in PS.
