Description

As there's been a start of a debate in a forum thread on cloud nights regarding my most recent image. Here's an apples to apples comparison of LRGB vs RGB processing with the same total exposure time.

RGB = 3h per color channel, total of 9h
LRGB = 4.5h of L, 1.5h per color channel, total of 9h

Both images were processed exactly the same way. A synthetic luminance was created and used for the RGB image.
