Nine years ago today my colleagues and i shot what likely remains the highest resolution ground based image of Saturn ever taken.
We used the 1m F/17 Cassegrain telescope at Pic du Midi Observatory nestled almost 10,000ft altitude in the French Pyrenees.
Many rarely seen details were captured, such as the multiple fine ringlets within the C-ring. The narrow Encke division was captured around the entire ring system. This division is only 200 miles wide spanning less than 0.1 arc seconds in angular width.
Atop the globe of the planet the famous hexagon shaped feature is clearly seen - a fast moving jet stream that encircles the polar region.
Saturn's rings will not appear this open again until 2031 - perhaps by which time an even better ground based image will have been taken!
