I went unguided at sidereal rate and was about 35 - 40 minutes from Luminance to last blue frame. Needless to say the comet moves a fair distance in that time.
I wondered if processing would be hopeless. It was not. I was able to align the comet image separately from the star field on the LRGB channels. The overall result turned out to be worth saving.
I have attached a midsized thumbnail - full sized image and exposure processing details are at:

Scope - Megrez II at f/2.6; Camera - ToUcam SC3. For reference to star charts, time was 15 Jan 2005 7:45 UT, North is 25 deg to the Right from top.
