    Thanks, Alain,
    this is definitely an ideal solution - but I have no SLR, and I haven't
    found anything similar on my Lumix GF2.
    
    It will certainly give as good timings, if the track is short, or the
    object is close to its start or end when it flashes or dips.
    Also for positional measurements, if you have a good way of calibrating the
    camera times.
    Lately, I did that by photographing the Time-the-Sat screen on my Android.
