    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.
    
    Observations with code 56 were measured manually and for the leo
    objects the observations were secured with an 80mm f/2.8 lens with

    Notes:
    ----------
    
    (1) Poor night with much cloud. Main purpose was to get the 71110 objects
        that have not been observed for several months and get a good track
        on USA 125R2.
    
    (2) Sorry for the delay in reporting - bit swamped at the moment with other
        space related matters.
    
    Cheers
    Greg
