    Notes:
    
    (1) Tips quite easy most of the passes. At 19h21m18s UT the length of the
        tether measured approximately 4.6 arc minutes. At 17h34m46s UT the
        approximate length was 5.5 arc minutes. Positions were taken for the
        middle of the tether.
    
    (2) Problem with the mount loosing azimuth position during high elevation
        passes not yet solved. Fortunately my "wide angle finder" which can
        see satellites down to about magnitude +8.3 allows me to keep the
        satellite in the field of view of the main camera which has a field
        of view 3x smaller.
    
    Cheers
    Greg
