Added my Second Pic from the BSG (M17). That little sucker is harder than it looks for some reason? Not quite happy but the best I can 'stretch it', next year need more subs with slightly better guiding.

Not to bad either Dave. It is a much harder target to process than it first appears. Such a wide range of reds and pale blues to get just right.
Your stars are suffering a bit from the hard stretching and are very white. A star mask might help keep some colour in them.
It's an object I've always struggled with, I suspect it needs lots of data and as Doug said, very fine stretching of the colours. Overall you've done well.
Nice, but agree with Marc about your black point.
Is the field properly flattened? My need some noise reduction more than black point (just speculating). I found collecting more blue than the other colours helped with M17 if any use too.
