Now I'm trying to get more detail out of Jupiter, since it seems to me that some of the festoons and plumes ought to be big enough to show up. Looking at Jupiter tonight, there was one really obvious festoon - at first glance I thought it was a moon shadow.

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.
