Just thought I would pass on this interesting news article that Bill found on the front page of the CBC website.
I arrived at the Binbrook main gate at 8:00pm - shortly after KerryAnn then Don showed up. I stayed until just after 11:00pm when my camera battery was just about to die - Don and Kerry were still hunting DSO's when I left.
I imaged using my new Canon 40D and timer remote through my Sigma 50-500 APO lens - I imaged at 191mm so I could leave the setup on auto-pilot (no guiding required) taking series of 2 minutes exposures for the Pleiades and 10 second exposures for the comet. The Pleiades and the comet:

As Tim mentioned, I also did some imaging. This time I concentrated on NGC253 Sculptor Galaxy. This almost edge on spiral galaxy looked fairly large and bright in the 6in SCT. Surprising, considering how close it is to the horizon. It is also very cool to be able to see some mottling in the eyepiece. I'm sure larger scopes will show much more.
Don wanted me to get a widefield image of Holmes... so here it is. I stacked a few 3 minute frames. I saw a pic on the web showing a very large and faint tail emanating from the soft edge and fanning out towards Mirfak and Delta Perseus. Pretty interesting eh? Anyway it is really hard to see, but the large fanning tail(extremely faint green hue) is just barely detectable in the image below. I will do another widefield image of this region... but with much longer and many more exposures to see if I can capture it better.
Below is another image which is a composite to try and show the very faint green outer halo and the bright compact inner core. Exposures ranged between 2 minutes and 30 seconds at iso800
Note: I posted a few more pics below in Glenn's post as well.
