Hello everyone,
I would like to share with you an old M42 that I shooted in 2010 more or less, and I have reprocessed this summer.
Is a refurbished image, so I don't have the exact data adquisition. More or less was:
20 or 30 x 600s@800ISO
some 120s@800ISO
some 60s@800ISO
and I think I did some 4s exposures for keeping the trapezium well exposed
The equipment was Borg 101ED f/4 + HEQ5 + 350D IR Modified (No cooled)
Regarding the process, I have 2 main objectives:
-To go the deepest possible
-To separate the emision nebula from the reflection one.
To achive the first objective I used MaskedSkecht and HDRWV
To achive the second one I splitted the image channels and worked them specially the B one, that has some gradient problems, maybe for bad flat fielding (I don't remember)
