NGC6888 HaL-HaRGB

Hi, this is my last attempt:
NGC6888 Wide field
Acquired under a a bad hazy sky at the beginning of last summer
HaL in HaRGB combine following Vicent linear methodology.
I added a BG mask to protect the non-ha signal in the HaL combine
Complex (for me of course:-)) elaboration of NGC6888 due to lack of o3 data and for the stars due to sky conditions.
The BG mask is the only way I found to prevent the NGC6888 to melt because of the strong Ha signal
Picture & some additional data at the link:

suggestions are very welcomed

I would slightly reduce a bluish cast. Otherwise is OK, nice work.
