I could be compleatly wrong though as i am not an expert in it but if you can explain to me how its changing that would be good to expand my knowledge.

In the past I have used CCDcap, Nebulosity, Maxim to capture, before settling down for Neb2. What I mean is that if you set Gain X, Offset Y in any of those programs it might not match and give you the same pedestal / background ADU. Neb2 and CCD cap where out by a lot I recall. Maxim seems to increase the gain more than Neb2 when you move from 1 to 10 for instance, in a
less linear fashion. I don't know if it's each software doing its thing or if it is the various different drivers needed to interface the camera with each software. That's why I'm saying if Gain1/Offset 60 works fine in Neb 2 and gives me 950ADU in skycount it won't in Maxim and vice versa. So the bottom line is Gain/Offset settings are not set in stone. They will vary depending on the capture software.
