Thanks for that, Greg. I'm starting to design a program that will sit between calibration and registration. It will go through each image that we took in a session in chronological order, and have a go at guestimating the residual image at the start of each exposure. It will have just two parameters: the strength of the residual image and the time constant for the exponential rate of decay. One can then use the guestimate to automatically either correct the actual image taken, or provide a set of weights for ignoring particular parts of the frame when stacking. That second part will sit on the back burner as we're busy fixing cattle yards and buying steers at the moment.
