Here are a couple of shots of Lovejoy, done by different methods.

Lovejoy was fairly racing across the sky, and its motion would have blurred it
against siderial tracking in more than a minute.

Hence the first method was to take 20 exposures of 1 min each tracked at
siderial rate, and stack in Registax, aligning on the comet.

The second method was to use PulseGuide software to measure the drift rate of
the comet, and, setting the Astro-Physics 900 mount to track at that estimated
rate, to take 4 exposures of 3 mins. each. These were also stacked in Registax,
aligning on the comet.

Results are similar. The longer total exposure of the first image gives a
smoother result. I tried again with longer exposures the following night. More
to follow.

I could not see the comet visually in any of my telescopes. The wonders of the
