    Hi all,
    Like Phil I was trying to image ISS , and was glued to the
    finderscope....when I reviewed the video my images were so blurred I thought
    I had set the focus wrong...but it looks as if we may have witnessed a water
    dump..can anyone confirm ?
    (Phil I'll send a copy of one of my images ASAP direct)
    N W UK.
