Saturn, 6th September: excellent seeing, spokes and Tethys transit

Hi all, here's a few images from my 6th September Saturn run in mostly really good seeing. Among the highlights are three spokes on the B Ring (see animated GIF and also at higher resolution here), a transit of Tethys later on, and disturbances in the South Equatorial Belt. The remnant of Saturn's Great White Storm of 2011 is a small dark spot in the first IR image (spot AV), thanks to Trevor Barry for highlighting that recently.

I even tried my first UV image of Saturn, which was tough as it's faint at those wavelengths, and unsurprisingly pretty grainy.

Part of a series of good seeing nights I've had lately, with a lot of Saturn processing still to go!
Clear skies,
Andy
