Another one finished. From the same imaging session on 23 Sep 13 - this dim object was actually my main target, and quite difficult processing, I must say (as it was clearly moving). It is pretty distant for getting a comet at nearly 3 times the distance to our sun. I did manage to pick up a not often imaged magnitude 13 galaxy just above the comet as a bonus, however (and described at the link, below).
Comet C/2012 F6 (Lemmon), 23 Sep 13
