Don't use TIF! Instead, convert the images to BMP format. I've been able to stack 70 or so 3072x2048 images that way. You can subtract darks and correct flat fields with Registax as well. I've had mixed results doing so, however. Unfortunately, Registax doesn't allow you to the scale flats or darks which is often necessary to get good results.
