    It would be interesting to know how many degrees the Sun was still above
    the horizon or how many minutes before sunset it was. I suppose Mir was
    in the eastern sky.

    My experience is that in order to illuminate enough pixels of the
    camcorder's CCD chip it is necessary to zoom in quite a bit. Anyway,
    only the brightest stars are recorded, at least with my SONY digital
    camcorder (analog models may be somewhat more sensitive).
    Even if you have recorded the position, this is of little use unless
    you also can determine the time to considerably better than 1 second.
