    There was an error in the image-annotation: Soyuz TMA-19 is at the Rassvet module. The POISK module
    is at the Zenit side and there is the Soyuz TMA-18 docked.
    This is the corrected version:

      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).
