Imaged Saturn October 28th 2019 from Sunset onward. The sky was very bright but initial data was quite reasonable.
The 685nm-Pass IR data very well resolves the vertices of the polar hexagon and polar vortex. Structure within the NPR is seen but is quite subtle. 
The animation of the IR data nicely shows the rotation of the vertices of the hex, it covers just over an hour of Saturn rotation.
The effects of the adjustments I had to make with the gain going from blue sky to past Sunset are quite apparent in the animation. 
The R and RGB data resolves a bright spot at approx Lat+30.5 L3 285.6
