If the lunar disk is larger than that, I crop each image twice, stack them separately, and then composite the two pieces. Another technique that works most of the time (not always) is to convert them bmp or jpg format which is smaller than the tif images. Also, make sure you have lots of space on your "C:" drive and defragment frequently. I defrag almost everytime I start to process a new set.

How are you handling the images? I have a question about Registax and your prime focus shots … whenever I try to stack multiple shots from my Canon Digital Rebel XT I get memory errors.
