G'day Dennis
. I will pass on your congratulatory comments to my colleague.
On the occasion in question he only tracked the stars, so the comet trailed slightly. He will have another attempt when the moon and smoke allow, using RGB filters, probably with half an hour for each colour, and attempt to track the comet.
. I have attached about a month out of an ephemeris that seems accurate so far, It has about two to three weeks left on it.
