I was testing some new gear on my telescope and everything worked so well that I decided to continue with the session. At around 3:00am, I recorded this image of the planet Jupiter with 3 of the Galilean Moons, Europa (with shadow), Io and Ganymede. You can just make out a little shading detail on Ganymede.
At the time, Jupiter was “in” the constellation of Libra, some 801,844,586 Kilometres from Earth. For those used to the “old” units, that equates to 498,243,126 miles.
Jupiter is the fifth planet from the Sun and the largest in the Solar System, with an equatorial diameter of 139,822 km and an Apparent Angular Diameter of 0° 00' 37".

The image is made up of frames processed from 30 sec duration movie files (AVI's) taken through Red, Green and Blue filters.
