Comments: Imaged Saturn October 21st in very ordinary seeing, have only 685nm IR data. The North polar vortex and vertices of the hexagon are surprising well resolved considering the conditions. Some of the concentric linear structure just inside the NPR is resolved and best seen in the IR animation. The animation reveals the long lived fast moving dark spot / bright spot combination at approx +64 degrees which is preceded by another thin bright band.
