Jupiter and Ganymede 
The weather cooled significantly here in England recently and the sky cleared for a couple of days. I was able to get this picture of Jupiter on Saturday night. I captured 4000 frames using my Orion SPX 250 telescope and used Registax 6 to stack the best 1400. The image was enhanced using that program's wavelets, and further tweaked using The Gimp.
Just off the edge of the disc of the planet in this picture is Jupiter's moon Ganymede, That is the third moon out from Jupiter and was one of the original four identified by Galileo. Ganymede orbits in about 7 days.
