    Observations 15 Nov 2011
    ----------------------------
    
    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.
    
    Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 05 sec min to 30 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done but dark field applied.
    Used with 102mm aperture f/2.56 refractor ,field of view 84 x 63
    arc minutes. Can get to magnitude 13 or so in less than 20 seconds
    exposure.
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is checked against GPS signal.
    Images processed and automatically reduced using APEX.

    NOTES:
    -------
    (1) relatively good session despite a fair bit of cloud from time
        to time. Basically trying out new version of CoSatrak improved
        by Mike McCants from Willie Koorts original version - improves
        my efficiency somewhat and also now enables me to get another
        magnitude or two on the fainter high altitude satellites.
    
    (2) Possibility that #20202 DSC 3-4 confused with WESTAR 4 - only
        one object seen - pretty faint - and both satellites appear to
        have been close together.
    
    (3) Only one position on DSP-F19 before it disappeared behind local
        tree- time my neighbour cut it down a bit but last time I did it
        I upset his wife because I cut down too much - why do people want
        useless unattractive trees in their yard ?
    
    (4) Still to report the other satellites observed with video, namely
        NOSS 6(A), NOSS 8(H),NOSS 5(C), DMSP F18, NOSS 1(A), 90070,
        NOSS 3-1(R), USA 186, NOSS 2-1(C, NOSS 2-1(D), USA 129 - will
        start on them shortly after I have given my eyes a rest - old eyes
        dont appreciate long spells of measuring!
    
    Cheers
    Greg
