Jupiter in HD

Up to now I've been using the venerable Philips SPC900NC webcam for imaging planets. At 640x480, it produces reasonably good images.

This video, however,  http://www.youtube.com/watch?v=Z0CXFbIKbKU   was taken with the next generation of webcam - Logitech Webcam Pro9000, at 1200x1600. Although it has been downsampled to a more common 720p (1280x720) format, it's still not too shabby.

The imaging train consisted of a Televue 4x Powermate and an Orion Sirius 17mm Plossl eyepiece.

As a side note, I'm very impressed with the performance of the Celestron EdgeHD 9.25" and its ability to support insane magnifications. Earlier one morning, I observed Jupiter with the 4x Powermate and a 13mm EP for a mag of 552x and the image was excellent. This compares very favorably with a high-end APO refractor I once had.
