On 25 November the shadow of Ganymede caused a partial eclipse of Callisto. They fitted just on my chip. Callisto is clearly darker than Ganymede. Unfortunately I woke too late, so a missed the beginning. Nevertheless it was worthwhile to rise early. Despite the moderate quality of the seeing some details are visible on both satellites.
I was able to record the last half of the partial eclipse of Callisto by the shadow of Ganymede with my C14 telescope at f/22 and made a small animation of the frames. Callisto has a diameter of only 1.2"; nevertheless some details are detectable. Does anybody know the name of the brighter spot at the lower left?
