THE BIG PICTURE
ANIMATION REVEALS MORE
Jupiter is a wonderful planet to image but if you take too long when collecting your images it’s easy to introduce motion blur, taking the edge off any fine detail. This is especially true when attempting to image special events such as transits of the Galilean moons.
The problem here is that you have two rapid motions to deal with; the spin of the planet and the relative motion of the moons and their shadows. Short captures are the key but can produce noisy results. A good compromise is to create an animation. The movement you record can produce a fascinating result that brings home how three-dimensional the Jovian system really is.
