    Observations 27 Oct 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.
    
    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 ~100mm focal length f/2.8 lens,integrating for 128 fields
    which is equivalent to a max exposure of 2.56 seconds maximum
    per image, but dependent on sky brightness. Field of view
    4.2 x 3.1 degrees.
    Individual frames are video time stamped with GPS derived signal.
    Images processed and measured manually.

    Notes:
    ---------
    (1) Too lazy today to report non-classified satellites seen :-))
