Jupiter rotation animation, July 24, 2009
He explained: "Begins with the Great Red Spot, when the planet was very low over the horizon, and ends when the spot of the impact ocults by one edge of the planet. Covers from 22:22 (U.T.) to 02:52 (U.T.). The images were captured with a LX200 10" Classic (very classic), plus one barlow x2 and a QHY 5C camera. The interval between images is 10 minutes. Each image is the result of the best 250 frames of every video, processed with Registax 5. When appeared the impact I thought I have a dust spot in the camera chip, until I relized that I was seeing the real impact. The composition of the animation was made first with layers in PhotoShop and then with ImageReady. Finally I reduced the composition at 75%."
