I have been meaning to look into building one myself. Flats for my ED72 I have been able to do with a graphics tablet I have lying around but it is not big enough for the SCT. I resorted to sky flats but to get the ADC I wanted at the longer exposure times that make an ASI294 behave it was into twilight and the ADU values changed by a lot over the run of flats. Like 30,000 to 15,000. The A2 panels would more than cover my SCT.
