Jupiter from a few weeks ago.

It just hasn't been a very good time these days for observing in Seattle.  Years ago, we seemed to have better skies, but just never seem to get very many really good nights these days.  Clouds, fog, crud or just plain unstable.
This photo of Jupiter was taken earlier this month on a fairly stable night.  I've done better, but I have to take what I can get.  Jupiter is in a very good position near the meridian after sunset now, so you don't have to stay up too late for the best viewing through less atmosphere.
This is about 600 frames stacked with Registax 6.  I got it running in Linux and for some reason it really performed well and was faster than Windows 7, but I think it may have been using dual processors for that, I'll have to experiment with both OSs for some more comparisons.  
Volcanic moon Io is casting the shadow on the planet clouds.  You can just make it out on the lower right in the cloud band.
