The seeing last night was fairly good, so I finally decided to dedicate an evening to imaging Saturn. I ended up with 4 useable image sets and this was from the last and longest set, taken just as Saturn was approaching the meridian. In fact, I stopped just as it was hitting 180 degrees south, as high as it was going to get. The RGB align function in Registax seemed to do a fairly good job correcting the atmospheric dispersion and the correction was as big as I have ever seen it.

Neat stuff!
