Hi Milton,

I think I'll only be able to engineer a one motor platform although I hear people actually autoguide and do long exposure DSO imaging on sophisticated platforms.

I am hoping to do as you suggest, collect so much light that I can run my Imaging Source OSC ccd at low gains and 30fps still at about 4000 mm focal length and make some Jupiter double transit shadow animations this summer.
