Hello, This may be for Bill... I saw a similar thread from 4 years ago but not enough info there to diagnose my issue. I have an ST-2000XCM. Attached are 2x2 binned dark and image files from last night. Note the 19 rows at the top of the dark frame with zero count, and the black/white rows at the top of the M3 image. This is a new problem, did not exist my previous night out a week ago. I tried various MaxIM settings, turning the cooler off, disconnecting/reconnecting, completely powering off/on, no joy. The camera is of course not worth a lot these days, maybe $500, but is it salvagable for cheap? Thanks, Craig
