Also, I'm challenging my assertion that I should be taking really short exposures. This time I took exposures long enough to use about 2/3 of the CCD's dynamic range. Seemed to work:

Admittedly, it's a better face than Jupiter showed last time, but the imagery is definitely sharper. Here's a close up:

I'm almost tempted to start displaying Jupiter at this resolution, which is a 2X blowup of the actual CCD image size.

For whatever reason, when I moved over to Saturn (I've actually gotten to where, even with the barlow, I can find the planet in the QuickCam using just the red-dot finder without looking through the scope) I decided to refocus. Bad idea, I think. I mean, it's not a bad image, I just don't think it is as sharp as the Jupiter one.
