    Excellent video! Kevin has given me permission to add this and his NOSS 2-1
    video to our NOSS web page, which I will do in the near future.
    
    Also, I tried my hand at reducing some observations, with the help of ObsReduce
    and a video de-compiler. Thank you, Allen Thomson, for clueing me in as to the
    common term for the latter; my intuition had been to search for a "software
    frame grabber", but that turned up little.
    
    Once I de-compiled Kevin's video into jpeg frames, it was easy to find several
    in which a satellite formed one of the geometrical patterns with the background
    stars supported by ObsReduce. Here are my results:

    Kevin may be following up with his own reductions.
    
    I found it easier to judge visual magnitude by watching the video.
    
    As expected, positional accuracy was on a par with the best achieved by skilled
    binoculars/stopwatch observers.
    
    Here are updated elements:

    Recently, I have begun to think about adding features to ObsReduce to better
    support still and video camera observers, and in the near future, I intend to
    start a thread outlining my perception of what is needed, and soliciting advice
    from observers.
