Great stuff Marc. I didn't realise you were still struggling to get the 9 out. That dark line was a problem with older drivers. Have you got the most recent one from the QHY site? For those the recommendation is now to leave clamping off and use normal speed download (most people tick "hold USB during download" or whatever the heck it says exactly)
Isn't it great when you can just keep zooming in down to the very last pixel on a mono camera
