I observed last night with my grabngo 102 mm F5 refractor. My rough sketches were only partially usable. The final sketch itself was quickly done, but scraping in the image processing took more time. It should be somewhat decently presentable, I think. Very much I am not satisfied with it. A ring system that would look like this in real life would tumble weird quickly I'm afraid. Also a bit ragged....
Seeing was fairly stable, I was able to get the maximum out of the achromatic with some ease with a 2.5mm Pentax-XO eyepiece.
Best impression of what I saw is when you look at the image from a distance of lets say nine feet.
