    In the images, for each one the telescope has moved slightly from 
    the last one.  Here's a spectacular set of six successive images 
    (that might make a very nice animated gif, with the satellites as 
    well as the trailed stars changing positions due to the changing 
    focus with 66-second one-chop time exposures).  The first two 
    show a single bright object.  The third one shows two more.  The 
    fourth one shows five of them!  Image five shows four, and the 
    sixth one is back to only one, as the telescope has moved its 
    focus on.

    not. If so, the main link to the entire sequence for that night is:
