    Showed are 2 frames out of a favorable pass on Aug 14 during the
    current morning-visibility period. It's interesting to see the
    minor changes of the detail by the seeing, although the
    conditions were quite good. This is a great illustration 
    of my general argument that stacking satellite images
    must be considered with care. As we never have many frames
    to stack, due to the fast movement and rapidly changing
    observing angle of the objects, the obtained average could
    be a more blurred result then one single frame provides. 
    Only in real exellent conditions, stacking satellite
    images starts to show gain.

    Imagery: manually tracked 10inch Newtonian @0.25''/p
    in quite steady conditions (but not excellent).
