No, he means your X2 TheSky driver. In that driver, there is no setting called "Offset". On my ASI071, there is "Brightness", "Gamma", "Bandwidth", "Gain", and "HighSpeedMode".
On my ASI120MM, there is "Gain", "Gamma", "Brightness", "BandWidth", and "HighSpeedMode".
So his question is my question, Which one of these variables is "offset" since that setting is missing in the X2 driver. The X2 driver applies to Windows, OS X, and Linux, which is why this is important. In Windows, I use ASCOM, but in Linux, I must use X2.
