I did not use a clock drive. At wide angles, or non-telescopic views, over a 15 second interval of time, the "streaking" is minimal.

I use the Panasonic LZ3. It has only 6x zoom. In order to get long exposures and have the focus at infinity, one has to use the "Stary Sky mode". This provides 15, 30 and 60 second exposures, unfortunately only at iso80. Attached is a picture of the comet taken from my backyard on 12 November 2007 at midnight, with the LZ3 clamped to the clockdrive of my telescope. The picture was taken at 5 Mpixel, this is maximum for the LZ3, saved in the best mode, with the LZ3 set to max zoom, 60 seconds and f/4.5. It was cropped and contrast enhanced in PhotoShop, then reduced in size to make it small enough for email. The sharp point of the stars shows that the LZ3 has a very good lens. If you look carefully you can see one or two stars throught the comet.
Without a clock drive you still can do good things with constellation pictures, but you the maximum exposure will be limited by the motion of the stars.
Enjoy.
