Aha! Had time to collimate the scope today - another learning process. It didn't seem too far out, but was definitely out.
Been watching Saturn again (don't see how one could tire of that) tonight, and wow the difference it made! The seeing tonight was much worse than the last couple of nights (with the naked eye it must be two magnitudes less), as it's been windy so there is a lot of dust in the air (we get that often, makes up for having such dark skies I guess). But despite that the collimation has made a huge difference, I could see so much more detail: clearly see a fine black shadow where the rings pass in front of the face, could see darker banding about half way down the face below the rings, could see Dione, Tethys and Rhea (but not Enceladus), and some of the time even part of the Cassini division was visible (at the ends of the rings).
A question: preceeding Saturn as it (rapidly) swam across the view were two 'stars', one significantly brighter than the other. Looking at the moon positions in Xephem I suspect that the brighter was Titan, is it likely the less bright one was Iapetus, bearing in mind I definitely couldn't see Enceladus - but Enceladus was much closer to Saturn's disc. Or were one or both actually stars? Anyone else viewing about 11pm?
The wind was a nightmare though, can't wait to have another go on a better night now!
Also saw what I suspect was the Tarantula nebula in the LMC, looks almost scary!
