    -------------------------------
    
    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.
    
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is automatically checked every minute against
    GPS signal.

    NOTES:
    ======
    (1) Rainy winter cold season really upon me and causing equipment
    to fail as it cant take the high humidity and low temperatures-a
    rather critical oscilloscope used to set the time from GPS failed
    tonight -- I dont know if my electronic abilities are good enough
    to repear it but will have a look but dont like playing around
    with 12kV on the oscilloscope tube! Fortunately the loss of this
    oscilloscope will not affect geosats but Ill have to make some
    other plan for leos.
    
    Cheers
    Greg.
