See this Comm Center thread by Danny Flippo. He has to put 90 sec as max exposure for flats to make it with Ha with his panel. Maybe start out with the shortest exposure and work up instead of the other way around (at least for panels). Or maybe look at the brightness numbers in FIlterInfo. Or add an additional field to FilterInfo for the max exposure.
Yeah, this is the simple, safe, and 80/20 solution. Forget the 6 hour estimated "hard way".
Instead of starting at full exposure, start at half and go from there. 90 seconds is ridiculous too, even with 255 brightness?
