Just finished reprocessing a video clip shot 8/13/08.....approx. 11pm PDT. Shot through a green filter without a barlow lens. If you look carefully, you can just make out Red Spot Jr. under the Great Red Spot (lower left). The dark spot in the upper band, right of center, is the shadow of Io. Before I could insert a barlow and refocus, the planet moved behind the trees.......preventing me from getting a largerv scale image.
