Thanks sil and Dunk, I appreciate the comments. Sil, I already crop pretty well with firecapture, so that part is covered. Recently I experimented with the real-time tighter cropping that firecapture can do, could be good for Jupiter and Saturn, but it does limit the framerate a bit. I'll look into the codecs too, and not keeping the intermediates is also a decent idea. Otherwise, hard drives it is! (just bought another

)
