The B&W version was taken in YL on Monday with my DIY 6" F4 Newtonian + Vixen corrector PH + 1600MM @570mm F3.8, single shot of 600s, auto level with STF in PI.
The color version was taken in Taiwan with Vixen FL55SS + Vixen HD flattener + 100Da @314mm F5.7, single shot of 360s @iso1600. Level adjustment in PS.
Seems the color version shows 100Da captured the faint nebulosity around M42 a little bit more. If this is correct, do you think it is better to use Ha or L channel for capturing more of the faint nebulosity?
Should use Ha or L channel ?
