Thanks Steve, Paul, Sean, Roberto and Paul M!

Roberto, I've been using anywhere from 300-500 frames and it seems to be enough given the gain of around 8-14. During the best seeing that I've had here I could stack about 50% of the video sequence. With this new ASI cam that could be up to 1600 frames, but after experimenting a bit it seems only very fine tonal qualities in the smooth maria are brought out more when large stack sizes are used. But sure if the seeings excellent might as well use as many frames as possible!

cheers

Mike
