The skies having thwarted my attempt to create a movie of the of the transiting of Io and Europa across the face of Jupiter did however allow me two 8 min stretches of time separated by one hour to create this stereo image. Let your eyes relax and focus on the image in the middle (if you can); notice that motion in one direction creates the effect of lifting of the screen (moons and shadows) while the other appears depressed (great red spot). This technique works great on the moon as well, allow one hour between shots for parallax.
