Image Description:
This is a time-lapse animation of Jupiter's moons. Each frame in the animation is separated by 2min of "real time", and consists of a stack of 45 exposures. Properly exposing the moons, however, resulted in an over-exposed Jupiter. So, I shot separate exposures of Jupiter and composited the whole mess in Photoshop, then used ImageReady to assemble the animation. Earth's north is up.
