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. > So the better question is, is USA 212 known well enough to be > "on track" or should I forget the telescope and use the binocs for now?? 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.
