I never expected to image today. It was mostly cloudy all day. But miraculously, it was clear in the SW where Saturn was. All around we had threatening thunderstorms! Seeing was very unstable because I had to image just before sunset and Saturn was very low in the sky! I had to use the QHY5III200M. This very low noise camera really help get the details out.
I could only use 1 set of RGB! Iapetus is located basically at the CM on the lower part of the ring. It was only visible in the Red filter and blurry in IR. I only did contrast enhancement because sharpening was too noisy.
Tomorrow is the Iapetus shadow transit! Hopefully conditions will be better.
