I have CCDStack, is there a process in this?

Hi George,
I've always wondered about that.
Also - what about using different exposure times for each of Red, Green & Blue
so that the final result is always 1:1 ?
( you would also have to allow for the band pass of the filter used in front of all other filters
such as the CLS-CCD filter that I use &
the quantum efficiency of the CCD chip at different wavelengths )
cheers
