The moons of Jupiter are in constant motion orbiting the planet and they can be so exciting to watch as they disappear behind the planet in an eclipse or transit across the face to create a dark shadow on the surface of the planet. This is sometimes referred to as ‘The dance of the planets’ and it’s like looking at a mini solar system in action.
There is an excellent planetary app called Gas Giants that helps greatly with identifying which moons are orbiting Jupiter & Saturn right at the time of viewing. You will find the free app at:
I took these images with a Meade 10-inch LX200 Schmidt-Cassegrain telescope and a ZWO 120 MC-S camera and 3x Barlow lens. AVI movie files were captured with 3000 frames and stacked in RegiStax6 and processed in PS CS4.
In the second image below I’ve marked the Galilean moons. This image is a composite, as I had to over expose Jupiter to capture the fainter moons. A wide-angle lens was attached to the ZWO camera to give a wider field to capture all the moons on show
