    Cosatrak 1 (Computerised satellite Tracking System).
    Program originally written by Willie Koorts and now being
    upgraded with numerous improvements by Mike McCants.
    The program is freeware so anyone who constructs such a
    system will be able to do what I can do.
    
    FLI ML8300M CCD camera with mechanical shutter + Trimble GPS
    receiver connected to PC. Software reads the GPS time and records
    start of exposure time to estimated accuracy of 0.00050 sec
    ( this reported by software in the FITS header).
    First use of software supplied for operating the camera - minor
    teething problems due to inexperience but nothing serious.
    Used with SKYWATCHER 102mm f/5 - focal length 502.3mm, field of
    view 122.7 x 92.6 arc minutes, image scale 8.86 arc sec/pixel.
    Camera was used in 1 bin mode - files 16 Mbytes and takes about
    7 seconds to read out.(one of my errors)
    
    Images automatically reduced using APEX.

    NOTES:
    --------
    (1) Brief 30 min clearing in almost continuous night cloud for the past
        week - I was getting desperate as I wanted to check out the new
        software.
        Fortunately stayed clear long enough to find some of the errors of my
        ways so next time will be more efficient. Still have to connect up
        the last part of the new equipment where the GPS 1 pulse per second
        operates the external trigger of the camera's mechanical shutter.
    
    Cheers
    Greg
