    Observations 20 October 2009
    -----------------------------------
    
    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.
    
    Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 5 sec min to 25 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done, but some done automatically in the auto reduction
    software.
    
    Used with 4 inch SKYWATCHER refractor- model 1025 - fitted with home
    made focal reducer to give an f/2.56 system. Image scale is 6.56 arc
    sec/pixel and field of view 84.8 x 63.2 arc minutes. Shows 15th
    magnitude stars in real time with reasonably good conditions.
    
    Video system used for the leo objects - STSS Dem payloads and
    DMSP F18 and measured manually. The high altitude stuff was
    automatically measured using APEX.
    
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is automatically checked every minute against
    GPS signal.

    NOTES:
    =========
    (1) Main purpose was to get positional data on DMSP F18 , the two STSS
        DEM mission payloads and 90085. Conditions rather poor with thick
        cirrus most of the time.
    
    (2) DMSP F18 did a brilliant flare to about mag +1 for about 15
        seconds.
    
    (3) The PAN satellite is slowly drifting westwards.
    
    Cheers
    Greg
