Hello Doug: Sommers-Bausch Observatory CU Colorado, has a 16803 + 7pos filter wheel + AO + HDMI Remote Guide Head on a Boller & Chivens 24" telescope. All SBIG. I'm having the same problem as the first post on this forum. I verified that the AO exercise worked at 1000ms 100ms and 10ms and took video of it. I used SkyX on Linux with the latest SBIG driver with AO, and also used CCDOps on a windows 10 machine with the same results. When I try to calibrate the AO after pointing to a good guide start it fails but also shows no movement at all of the AO plate (or star) during calibration. Also I used the instructions from the SkyX manual but I wonder if there are any special setting I need to know about for CCDOps? Thank you. Fabio.
