Good to know Peter but a shame we have to go to that extent and cost to get something fixed, I remember a chap named Theo GAMA used to sell QHY cameras and could check them out. Turns out a few years ago (2020) I might have thrown away a good QHY8 camera because of driver issues. I posted here if anyone had any clues and never got a response. Turns out that it may have been a driver issue this time around too as worked flawlessly last night after reinstalling the drivers
