Planet Jupiter: image taken on January 3rd 2003 with Celestron 9 1/4 and digital camera Olympus C2100.

On can see the cloud structures in the atmosphere of the planet, which ist the largest in our solar system. As we see, the shape of the planets disc is not circular, which is due to the fast rotational speed of less than 10 hours for one rotation.  
 

Planet Jupiter
Planet Saturn Planet Saturn: exposure data as above.

The rings of Saturn consist of small fragments of ice or rock, which are moving around the planet comparable a large number of small satellites.

At the outer edge of the ring one can detect the dark Cassini gap, which is named after its discoverer. This gap is probably due to the fact that any particle within it would have an orbital period around the planet which is exactly half the orbital period of the satellite Mimas. So the gravitational force of Mimas would remove any particle out of the gap.
There are several resonances also with other satellites, which lead to a number of small gaps which are mostly not visible with earth bound telescopes.
