Not yet, but I do know the II works an absolute treat with the 80. Better than any in the price range and I've tried 4 different reducers, the WO 0.8x, the Meade and Celestron 0.63x and the Mogg 0.66x. In the 80 the WO leaves them all for dead as far as flattening the field is concerned, though there is some vignetting.
I'd better finish that review one day and get it to Mike to post
