Get back home, see the sun, pulled out my setup. The iOptron works now but I had little time to test it. It's cloudy and I never got a clear sky, so I didn't even open the window of the air-conditioned room, hey, it's lie 34 degree Celcius outside!
Just a record, very poor image indeed. Registax couldn't really process this video with moving cloud. avistack does not like 12-bit video it seems.
AR1093 and AR1099 just before their departure.
