I had noticed that Comet 78P/Gehrels was fairly close to Jupiter so might make a worthwhile early evening target despite being small and quite faint at around mag.10. It took me a while to be sure that I had found it but once underway I aquired a series of 40 x 3 minute exposures covering a period of just over 2 hours (a couple of exposures had to be dumped with guiding errors which show as small breaks in the star trails early on in the stacked image). It was the observatory roof that halted any more exposures. Details: 10" f4.3 Newt. 38 x 3 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT (stacked in Nebulosity).
