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
      Transit      21h31m07s   3.1m  az:185.6d  S  h:83.4d
                   dist:442.2km  alt:439.5km
      Disappears   21h32m19s   3.7m  az:101.3d ESE  h:38.4d

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(
