Found the problem. Originally I was using TVDEE drivers but changed to QHY drivers to get the 4x4 binning. Now I find with this installation Im getting a lot of read out noise and the offset settings have to be increased to ~120 to get a pixel reading of ~1000. Previously my offset was 50-65 to get the SAME value with TVDEE drivers. I have gone back to the TVDEE drivers as these give absolutely noise free images.
When I upgraded to the QHY drivers I assumed that the offset settings would be the same- not so at those settings for the TVDEE drivers 65 offset, the ADU reading was 0.
Find it interesting that now Im getting download noise with the qhy drivers and not TVDEE drivers????
