Description

Yes, yet another conjunction image, but Ganymede was transiting the Jovian disk at the time of this exposure (1/22/2020 @ 0137 UT)! It is (barely) visible as a tiny dark fleck against the disk.

This image is a composite of 3 separate stacks, one exposed for Jupiter (4 ms), one for Saturn (8 ms), and one for the moons (100 ms). I wanted a relatively natural feel to it so I tried to preserve some sense of the relative brightnesses of the objects while still making them visible to the eye and not saturating any of them. Thanks for looking and Merry Christmas to everyone!
