I had some good seeing last friday. Here is Saturn in colour, UV and methane bands. The colour image shows the Encke division (also called Keeler division) in the outermost part of the A ring. The C ring (crepe ring) is also visible between the planet and the bright B ring. The planet is visible shining through the C ring.
The UV and methane band images are interesting because they show almost complementary views. The UV image shows a UV-dark belt between -42 and -52 degrees south, as well as a dark equatorial region. The methane image shows a methane-dark belt between -18 and -33 degrees south, and a bright equatorial region. In general, features dark in UV are bright in the methane image.
