A year and a half and no answers... Wow.
I've been running the ASI6200MC with a Celestron C11 Edge HD with the designated F/7 reducer (FL 1,960mm) with GAIN set to 100, OFFSET set to 50, and TEMP set to -10°C.
Here are two images taken with the settings listed above and 30s exposures (integration time listed next to object name below):
Horsehead (2h 35m)
Orion (55m)
