NGC6888 HaL-HaRGB

[lucchett]

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.

Thanks,
the high gamut LCD need to be well calibrated...
I will refine it, I hope i didn't clip anything
