Remarks:
----------
(1) Still experimenting using video, this time trying a 200mm
     lens for geostationary satellites. Unfortunately the video
     camera has so many hot pixels that it is not really worth
     the effort. 200mm focal length is also too long for LEO
     satellites so next try I will set the lens at 150mm.

(2) Also tested a WATEC 902H Supreme side by side against the
     Mintron video camera and as far as I am concerned there is
     no comparison - the MINTRON wins every time because of its
     integration mode.

Cheers
Greg
