I enjoyed some fantastic views through the scope. When I first got it, it was very unusual to see a 6 inch apo refractor at star parties or clubs, most people, including myself, were blown away by the views. The first time I saw Jupiter in excellent seeing was amazing. It looked like one of those 70's liquid sculpture toys, where you turn the plastic box around & the different colored oils flow around each other. You could definitely get a feeling that Jupiter was liquid, seeing all the different bands & globules flowing around each other, inside the GRS, etc.
There was slight false color on Jupiter, probably on 1st magnitude stars too, but it was never something I noticed or thought about. I used it mostly for deep sky. Usually I would see detail that was listed in observing guides as being visible only in 8-10 inch telescopes and above.
In the newer scope, the one improvement that stands out visually is planetary colors seem to be rendered a little more accurately and clearly. You'd notice it if the scopes were side-by-side, but overall I don't think it affects image quality that much. The non-ED scope is 10 times sharper than a 10 inch SCT, the newer one is 11 times sharper.
I think many of the improvements in these scopes over the years are directed at imaging users. The current AP focussers are works of mechanical art and extremely solid, but the focusser on my old scope worked smoothly for visual use, and the tube was very lightweight also. I remember looking at Hale-Bopp and seeing some astounding high-contrast views of the spinning nucleus.
So what do you think of the scope???
PS, Joe Bergeron has some detailed writings about this scope on his website that you'll enjoy reading.
