    Observations 18 Oct 2009- Part 2
    -------------------------------------
    
    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 MINTRON used for leo objects that
    require a time resolution of at least 0.1 second.
    
    (1)~100mm focal length f/2.5 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 2.6 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) The above were observed with the video system so reduced manually.
    
    (2) The remaining observations done with the 4 inch refractor and
        processed with APEX will be posted shortly then I think I am up-to-
        date as I want to do a short observing spell tonight for some objects
        of interest.
    
    Cheers
    Greg
