Other (optional): This image is very important to me because it was taken only 1 month after getting my first ccd camera and managing to capture a very rare moment with all 4 major moons in the field of view, with a transit, and in addition the Red Spot in view. Conditions were clear. Date 22nd. June 2005.
Point of Interest is the large shadow of Callisto. This may be due to the fact that the shadow fell on the polar side of the planet, thus distributing the shadow over a larger area than normal. This is the interpretation of those who I contacted about it.
