    Observations 14 Jan 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.
    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.
    
    (1)Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 10 sec min to 60 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done.
    Used with 200mm focal length telephoto lens operating
    at f/2.8. Field of view 1.8 x 1.4 degrees and showing 12th -13th
    magnitude geosats.
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is automatically checked every minute against
    GPS signal.

    Notes:
    -----------
    
    (1) Sorry for the delay - I was in hopsital for a few days so could not
        process the observations.
    
    (2) Still have the observations made with the video set-up to report.
    
        The satellites are:
    
        SDS-3F5,USA 189r,90070 and MSX
    
    (3) I hope to do some limited observing tonight.
    
    Cheers
    Greg
