I was the prior owner Brian refers to. Indeed, a fantastic scope. I too sold mine to afford an FSQ106ED, and I regretted every second of it - in my opinion, the DED EXCEEDS the FSQ in terms of image quality (and that is a difficult statement to make!). I understand Vixen was unsuccessful with the DED simply due to costs involved - the 2nd generation DED's were not as good as the first (which I owned), and this lead to the demise of the system. A shame - even Markus Ludes commented on the pros f the DED vs the FSQ. In fact, when I sold my FSQ, I re-acquired my Vixen FL102S that I too stupidly sold to afford the FSQ... and I don't regret that either! The FL102S is a simply superb telescope. A friend of mine recently re-acquired my former DED - I am going to try my best to twist his arm to take her back.
