Saturn at 18.4" diameter





























This is my latest observation of Saturn taken last night from my observatory at around 21:30 UT. Seeing conditions were not optimal, and images were not steady at both f/20 and f/25. So I had to remove the barlow lens. These images were taken at the native f/11.

At f/11 the major rings and divisions are all well distinguished. The Enke and Keeler divisions (in A) as well as the (C) ring are visible, together with other additional ringlets in (B).

The Polar Hexagon at the SPC is distinct especially in the monochrome image. The distinct colours of the SPC, SPR and SSTeZ regions are very prominent.

Comments are welcome.
