OK Thanks.
Hopefully I will get some traction over on the QHY forum.
One additional thing I noticed in comparing the fits headers, their's has EXPOSURE in ms, and SGP's in in Seconds. From my research seconds is correct.
Is it possible that you are asking for a 120 second exposure and getting back a 120ms exposure? It does take 120 seconds on the progress bar in SGP, but I don't know if you are waiting the 120 seconds to ask for or check the download or it you get the image as soon as the camera is done?
