    Quick experiment last night to see if capturing at 20fps   320 x 240 could 
    produce any detail .( webcam at prime focus LX90 8 inch ....   FOV 5 arc 
    minutes )
    
    Used ROSAT as a target.
    
          21h31m07s Rosat
          (20638 1990-49-A) Appears      21h25m33s   9.2m  az:273.4d   W

    Resultant wmv file here :

    about 150kb.
    
    
    In the original 3mb gif animation , some slight detail can be seen , but 
    ROSAT is rather unconventional in shape and I have come to the conclusion 
    that frame size needs to be 640 x 480 minimum.  ;o(
