Observed from my carport. All went well, until I sent to the target, and the aim was too far off to then ID the star field in time. Later, looking at a wider view of the C2A chart, more than I plotted for the "chip" view, then I could see where I was aimed. Lesson learned - don't scrimp on the size of the chip field. Make it as wide as the q70 view as a minimum, given the not always great GoTo pointing accuracy of my 8SE.

Looks like a miss for 4320 P-L, 2x from home on Mar. 19. No apparent event.  PyOTE detectability tool reports an event as short as .070s would likely be detectable, predicted max was 0.66s. I was outside the path but inside the 1-sigma, rank was only 67. Chris Anderson got a 0.5s positive 6km from me, within the predicted path.

Tried it from home, but could not ID the star field, like RN.
