If I had a way of measuring seeing, I would certainly try to implement something. I have had done some exploration with others about trying to measure the apparent/absolute magnitude of the sky (like a proper SQM). It is extremely difficult. Measuring magnitude would require controlling for 2 variables that are unique to almost every allsky camera: QE/frequency response of the sensor and the lens.

I would love some help in getting even a close approximation of magnitude converting an ADU value to a magnitude. It would almost certainly require some local offset for every camera/lens combination, I just do not quite understand the math involved.
