I have reviewed my test images, shot is both Ha and Lum, these were simple star shots at various shot (30 & 60") sub lengths - they are completely black (with the exception of some noise). It would appear that I am getting nothing now from the camera, even though the download runs and the star analyser runs and it saves the file - there is nothing there apparently. And no the scope cap was not on, and the camera was powered and cooled and connected in SGP. Funny thing is that 10" Frame and Focus images worked but looked strange, very washed out.
I'm at the point of looking for another camera control app. I will test again when I can with Sharpcap.
