Comet 103P - Hartley2

Details and link to video here:

The field of view is approx. 26.4 arc-minutes. So, this puppy was moving pretty
quickly - timespan was 1.5 hours.

By the way, with the new autoguiding set-up (Lodestar/Stellarvue 50mm Barlowed),
I'm getting an RMS of 0.42 arc-seconds. Compared to the Q-Guide (QHY5), the
Lodestar is *much* more sensitive, presents cleaner images and downloads a lot
faster, which seems to improve the responsiveness of sending corrections to the
mount. With the previous QHY5, PHD would exhibit delays.
