Our largest planet in the solar system is very close to Earth this time of year and is about to be at opposition. This is the brightest object in the sky other than the moon (for the time being anyway).
This image was aquired with a Phillips TouCam webcam. It was taken at 10 frames per second for 3 minutes. That's a total of 1800 frames. Frames were stacked using software for the final result.
On some nights, you can see it's four main moons (Io, Europa, Ganymede, and Callisto) cast a shadow on the planet as they orbit the planet with an 8" or larger telescope.
Image was taken around midnight on September 30, 2011 from my back yard in Midland, TX. Clear skies with excellent seeing and transparent skies. Some light pollution. Used without filters and guided.
