    Observations 24 August 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.
    
    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) Some activity in the region of WGS-F2 #34713) field where WGS-F2
        should be close to DSCS3-13 #27691 but NOT seen. Also in the field
        of view was Intelsat 904 and an SL-12 R/B(2). I am reasonably
        certain I have correctly identified DSCS3-13,Intelsat 904 and the
        SL-12 R/B(2) but on the edge of the field was an unknown satellite
        called 0004 in my report. Might this perhaps be WGS-F2 on the move?
    (2) If I feel energetic tomorrow I may process some video observations
        obtained.
    (3) For once Im glad its cloudy tonight :-))
    
    Cheers
    Greg
