Observations 30 Oct 2009
----------------------------
Cosatrak 1 (Computerised satellite Tracking System).
Camera mount now carries two systems that can be operated
together as two totally different sytems and computers used.
Generally the DSI Pro II camera will be used for high altitude
slow moving objects and the video for low altitude satellites.
~100mm focal length f/2.8 lens fitted to MINTRON low light
level CCD surveillance camera (0.005 lux typical in non integration
mode) and 0.00005 lux in STARLIGHT mode with 128 frame integration.
Image integrated for 2.56 seconds but exposure depends on sky background
brightness. Field of view 3.3 x 2.8 degrees and showing about mag +12
stars in "real time". Used as a finder for the 4 inch refractor.
Individual frames are video time stamped with GPS derived signal.
Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,
Elevation 10 metres-situated in Pinelands (Cape Town),South Africa

Notes:
-------
(1) Observing intention was to only look for USA 186. Got what I believe
to be the satellite running about 6 minutes early. Nothing bright
predicted to be in the area around the time observed.
(2) Last point in shadow but good.
Cheers
