Thanks guys,
I've often looked at the AO units and wondered about their ability. I suppose with good PEC and AO you could compensate for a better mount. I must admit that from where I am at the moment, I don't really see a G11 as step up, and would think about an AP900 or the new Paramount Mini.
I'm pretty happy with the star shapes and guiding has improved a measurable amount, however I do realize it still could be better. I am going to invest in a nice moonlite focuser and robofocus and ditch the guide scope and go to an OAG. We will see what results those changes brings as I do not think that I have yet got the most out of the gear I have at the moment.
Cheers!
