    subject: a success-full telescopic observing night
    Just want to let you know that I managed to capture in one night with
    fortunately very good seeing 3 satellites which were for a longer time 
    on my list of favorites to capture at 0.25''/p with the reflector. 
    All 3 are in the catogory 500-600 km orbiting altitude. 
    1)Finally got Terra (25994 1999-068-A)
     during a favorable 80 pass. Only slightly faring, which
    was actually optimal, as otherwise detail would have been totally overexposed.
    First frame-inspections already show nice comparable difined shape.
    2) ERBS,(15354 1984-108-B) as mentioned yesterday, deployed by the Challenger on STS-41G
    This looks to be a very small object but with defined obvious color as
    first frame-inspections suggest.
    3)USA-161,(26934 2001-044-A) Keyhole sat. (captured during short flare!) .Probably a US military reconnaissance spacecraft
    member of the Keyhole constellation that provides images at 15cm resolution. Looks similar to the 
    Hubble Space Telescope. Actually my first capture of a real KH-satellite, although I earlier had captures 
    of some of the Lacrosses.
    When processed, I will present the results certainly here on the list.
