Image Description:

A decent Jupiter picture, but DSLRs just can't compete with webcams for planetary imaging in my opinion. The dark spot in the center of the North Equatorial Band is Jupiter's moon Ganymede. The pale, reddish patch on the far right side of the South Equatorial Band is Jupiter's Great Red Spot, affectionately known these days as the Great Pale Spot, since it's color has faded over the years. This is a crop of the full-size image. Earth's North is up, so Jupiter appears tilted counter-clockwise by 23.5°.
