    I am trying to calculate the 33% and 50% saturation levels for this camera in order to do flat-field images. The Full Well Capacity is 60,000, but I need the “Gain” (Electrons per ADU) to calculate the Saturation. If it appears in the Specs, I don’t see it.
    Would someone please help me with this?
    Thank you.

    If you take an image with CCDOPS or MaxIm DL (and probably other software), the EGAIN parameter in the FITS header will give you photoelectrons per ADU.

    That said, cameras are set up so that the saturation point of the CCD sensor is at the 65,535 ADU level.
