    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 STSS DEMO objects - 100mm telephoto f/2.8
    lens + Mintron surveillance camera, with time stamping of individual
    frames. Automatic tracking on satellites.
    
    Exposure time to nearest second inserted into image FITS header
