Saturn in good seeing 3/3UT - spot animation now added

Hi
Scored a short burst of nice seeing at about 5 this morning. Thankfully the computer had come back to life by then - after the update installed itself and shut everything down (the warning is along the lines "installing updates, please do not shut down your computer" - it should be "please do not throw your computer against the wall" ).

This is the first image of the session that I have had time to to process and I will not get to it again for a little while - will post more later. Two versions are of the same image and show what I consider to be normal processing and excess sharpening to bring out some of the features. Left the enhanced one at full drizzle size - It looked OK when large. Apart from Encke, there is definitely some spoke structure and I will have to very carefully process the surrounding images to make an animation (edit - not as definite as first thought) - is there some electrical activity going on at present?. Tehys is also visible on the upper right - it turned up with no extra enhancement or even its own track box, so the seeing was pretty good.

the other thing that was visible in the raw feeds was the dark junction where the rings go behind the disk on the right had side - I had thought it was a stacking artefact, but it seems it isn't.

thanks for looking. regards ray

edit: just added red channel animation - no sign of consistent structure moving in the rings
