Thank you all. I am learning a lot of information which will doubtless come in useful one day. Although the SX 814 now used has a CCD chip it seems inevitable that I will need to use a CMOS device sooner or later.
Actually, I have already used CMOS sensors in extremely elderly Canon DSLRs. I have not yet attempted to do photometry at anything better than 100mmg accuracy or precision. 2mmag is possible with the SX camera.
