At f11 even a semi apo should be pretty apo...in theory. It is crazy why they don't just tell you the Abbe number for ED glass. We should petition for this :)  

Thats part of what makes me question what im buying, I came very very close to the AAf11ED, and I was planning to visit the show, but for a sicky baby and nasty letter from HMRC I would have, and would probably have walked away with one.. but at the back of mind, having owned a aa72mm ED which they themselves termed a semi apo due to fringing why all of a sudden, across numerous quarters a hush on this element..the new 72mm ED skywatcher and 150ED, now the AaF11.. surely as a consumer you've a right to know the fuel they run on..
