Description

Wide field capture of Lagoon and Trifid.  I ended up mostly using broadband data with the exception of H-alpha for R.  Stars are RGB and everything else is HaGB.

Description: Added narrowband data, switched to narrowband nebula with RGB stars. Took some fiddling to get stars to not be blowing out a ton in the combination but figured out a mask based on the NB stars. I'd like to get better blue around Trifid though, the RGB is better for this. May try some combination of just RGB Trifid in the future.

Description: HaGB version to get real data for the blue around Trifid. And I used a technique in the HSI color space to retain color while increasing contrast. Just extract H and Si before HDRMT and LHE, do your contrast adjustments, extract I, then combine.

E

Description: Bit less intense red, especially in the core of each nebula where I boosted the blues a bit. Further tweaks will require looking at the data before blending into HaGB.. I might have boosted saturation a little bit before that. And the % of H-alpha used could be lowered more. I did the combination with non-linear data.

Description: Added some green and blue back into the O3 regions. Less pink in the core with a little more contrast.
