    You did a nice job helping us stay in the game on that rapid decayer (09052C
    / 35939), with the binocs, and especially the video obs on the two nights
    before decay.

    Barring a large manoeuvre, for near-term predictions, the elements are
    sufficiently accurate to keep cross-track uncertainty well within about 0.2
    deg, so your telescope's FOV should not be a problem.
