    Observations 22 August 2008:
    -----------------------------------
    
    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 sesnitivity
    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) 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.
    Used with 135mm focal length f/2.8 lens,integrating for 128 frames
    which is equivalent to a max exposure of 2.56 seconds maximum
    per image. Field of view 2.7 x 2.1 degrees.
    Individual frames are video time stamped with GPS derived signal.
    
    (2)Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 20 sec min to 60 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done but dark field applied.
    Used with 200mm focal length f/2.8 Nikkon telephoto lens,
    field of view 1.88 x 1.40 degrees. Can get to magnitude 13
    or so in less than 20 seconds exposure.
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is automatically checked every minute against
    GPS signal.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres-situated in Pinelands (Cape Town),South Africa

    Notes:
    ---------
    
    (1) DSP-F5 #08482 - faint - not 100% confident as at limit of 200mm
        telephoto lens capability - only seen on one frame.
