Fantastic!!!

That image really shows the power of the dispersion corrector (since Saturn is so low in the sky).

Lovely ring structure and shadows.  Processed to look very natural.

Excellent!  That really is a beautiful result.

Wowser! That's stunning!!

[The Thing]

Thanks guys. I'm well pleased with it. I have updated and added a version with WinJUPOS de-rotation. There is slightly more detail if you squint |)

Winjupos definitely gives a better result! well done again Duncan!!
