    Hi all-- this was the image taken during that very bright ISS-pass
    Marco and others reported. As you can see, especially the port-1
    radiators are very bright. The image may present not well how bright
    this radiator actually was flaring, but if I tell you that in all
    other ISS passes I imaged over the past 3 years, the radiators never
    were overexposed, says enough.
    When I saw the results I took on May 4th during one of the 2 favorable 
    ISS passes of the evening, I was amazed by the clearity of the Cupola 
    I saw on the images. You can actually recognize the 7 single windows, 
    6 side-windows and one top-window. The diameter of the Cupola is around 
    2 metres. I have added a partial enlargement with some higher contrast 
    and a comparison. (10inch Newtonian, manually tracked)
