This is my worst ever Saturn. But I thought I'd post it anyway. It was done last night as a test of the 50 frames/sec 640x480 crop mode video on the Canon 550D. 500 frames processed in Registax:

Here's a single frame:

The seeing was bad and look at that atmospheric dispersion :( - Saturn was only 20 degrees above the horizon.
Sadly, that pixel for pixel video mode was dropped from the 600D.
Forgot to say it was on the Celestron C11 with a x2 Barlow.
