can you post the 5139 here with offset gain and exposure please?

I'll post you an example frame with a 300second exposure when I get home.

Offset and gain however are sensor specific and it's up to you to calibrate your camera to suit. I have seen some wildly different settings all working well, and likewise when someone copied my settings at astrofest last year the rest was bright green bleeding all over the frame.

Instructions for setting the offset and bias are in the QHY10 manual http://qhyccd.com/file/repository/PD...r%20manual.pdf and relies on the Noise Analysis function of EZCAP. It involves taking a dark frame with lens cap on and a bright frame so you can do it during the day.
