Ditto, Mark's question. I'd be very interested in doing video, especially multistation, but not if it meant giving up my visual program: I like adding to the science a LOT, but I like sitting out under the stars on a clear quiet night even more! :) Thanks for the helpful advice and cautions so far, Sirko. Let's keep this thread going - it's getting down to the nitty-gritty! Clear skies, Lew
