Interesting proposition, Wavy.
Saturn's glare ramps up the challenge.
Three nights ago I managed to see Enceladus which was very close to the rings using n 8" f/4 dob from home here in Sydney. I thought I could just make out Mimas, but its even closer proximity to the rings and dodgy seeing I can't count it as seen. Image wasn't stable enough and the glare of the planet proved too much, so for now I'll just say Enceladus
I'll keep pushing with different scopes and see what each has to say under different skies too.
