    in non integration mode) and 0.00005 lux in STARLIGHT mode with 128
    frame integration.
    
    Used with 200mm focal length f/3.5 lens,integrating for 96 frames

    Notes:
    --------------
    
    (1) #90072 aka ESA 96056  DSP-F5 , bright flashing
    
    (2) #90042 aka ESA 96066
    
    (3) #90066 aka ESA 96003
    
    (4) #90025 not seen last two tracking sessions - guess its moved again.
    
    (5) #90051 again not seen - looks like it has also changed its
        geostationary location, as has #90016 which is currently lost to
        amateur trackers.
    
    (6) As soon as weather conditions improve- ie around September or so, I
        will again use my 6 inch f/5 reflector to locate the fainter
        geostationary satellites that have not been observed for some months
        now. This scope can see geostationary satellites down to magnitude
        +16 in "real time" and spotting geostationary satelites is a "piece
        of cake!".
    
    
    (7) This concludes observations 17 July 2007
    
    Cheers
    Greg
