If you've got multiple series of exposures of the same object, captured on multiple nights, so the sky brightness varies between them (and their exposure length varies also) these frames can not be simply combined, the average of them would be meaningless, correct? What happens in the combine in an application like Maxim when the base background brightness varies a lot?

Isn't this what "Normalizing" and exposure is for?
