ATIK 383L+ color color scaling in maxim dl problem

[Grzegorz Czernecki]

I have a question for atik383L + color owners, what is the correct scaling for this camera in maximdl in the convert color tab?

Not sure if there is proper answer to that question.

If you want to get realistic colors from your sensor, simple scaling is not the best way to do it - it is approximation. In fact, even more "sophisticated" methods are still approximation to some degree.

For better results you want to use color conversion matrix rather than simple scaling. Simple color scaling is a kind of color conversion matrix - but only diagonal one.

In any case, to determine suitable scaling - you can use a single star in your subs. Find a star of certain stellar type that will be your "white point". Probably best stellar class for this is F2 (non of the stars is pure white, some recommend using G type, although those are yellow stars, and some will use A class - that is bluish star). Take image of that star and compare intensity of each color - and that way you will get scaling factors (one that you should use to get star colors to be 1, 1, 1).
