    Observations 20 JAN 2011
    --------------------------------------
    
    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. Tests seem to indicate that its sensitivity
    is comparable to the MINTRON ( possibly better) but as its not
    possible (?) to time stamp to better than 1 second accuracy the
    time resolution is not good enough for LEO objects.
    
    (1) 145mm 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 2.5 x 1.9 degrees and showing about mag +12
    stars in "real time".
    
    Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,
    Elevation 10 metres-situated in Pinelands (Cape Town),South Africa

    NOTES:-
    ============
    (1) Despite a full moon not a problem.
    
    (2) Due to a prolonged senior moment I wasted the first half of the
        observing session before I found the errors of my ways.
    
    (3) Japanese IGS satellites a bit difficult to observe. At best they
        normally only just clear the house roofs to my south so I only have
        a few seconds to see them before shadow entry. Despite this managed
        to recover two not seen for about 3 months.
    
    (4) No tracking tonight - too tired. Will try for the new NROL launch
        my sunday morning. Dont really expect a problem-other than the
        lousy time! I need my beauty sleep otherwise my wife will divorce
        me!
    
    Cheers
    Greg
