That is why I am thinking going back to the virtual WinXP and the 10 year old software. It was simply working every night!

All the hardware is still the same except the new control computer (Win10) and the new CCD (SBIG STX-16803), but all the software is new. Everything is almost perfectly working, we have lost very few nights and made some very nice observations already with hundreds of science images taken with ACP. It is more like the extra hassle to restart the stuck focuser software etc that is causing some pain.
