    Observations 13 Nov 2011 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. 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 135mm focal length f/2.5 lens,integrating for 128 fields
    Field of view 2.4 x 1.8 degrees.
    Individual frames are video time stamped with GPS derived signal.
    Images processed and measured manually.

    NOTES:
    ------
    (1) The last two strays seen were picked up in a high speed orbit plane
        scan for 90077 - which was not seen. Using a new scan program written
        by Mike McCants it is possible to scan an orbit plane fairly rapidly.
        In this particular example some 80 minutes of the orbit was scanned
        in 16 minutes. Some more scans will be carried out when 90077 is
        better placed for a longer scan now that the moon is out of the
        evening sky.
    
    Cheers
    Greg
