Canon EF 200mm with aperture mask @ ~f/4 (2" Idas LPS-D1 in front of lens)

Comparison of two different processing versions (Tone Mapping vs. NBRGB script)

Version "A" (Original)



Processing version with Color Tone Mapping method (R=Ha, G=O3, B=O3) and synthetic luminance.

"B"



Ha-O3-O3 (R-G-B) color tone map using star removal with Straton; Luminance from HaO3RGB integration.

Version "F"



Pixinsight processing:

- DBE all channels R G B Ha O3;

- Cannel combine RGB and SynL (integrate all channels)

- add Ha using NBRGB script (linear data)…. saturation <0.5, lightness >0.5

- add Luminance using LRVB script (stretched data)

Version "G" (Final)



50 / 50% blend between "A" (original) and "C" to average both processing versions
