Comet 78P/Gehrels, 2011 September
This periodic comet was too faint to see in the telescope. This was perhaps because, being in Pisces directly under the square of Pegasus. it was only at an altitude of about 20° from my position. I used some star-hopping software of my own to find it from its predicted coordinates. Processing the stack of photos revealed it (just):
