Phil,
The Vixen LV's are a fine planetary eyepiece, infinitely superior to anything made in the far east but very marginally behind a good ortho or top grade plossl. Just as sharp on axis but slightly down on light transmission IMO by about 5%. This however, is something that takes an experienced observer to detect and to a lot of people the difference would be undetectable. Considering they preserve the 20mm of eye-relief in all focal lengths they are very hard to beat. AFOV is narrow compared to the premium widefields and similar to an ortho, however on a tracking scope as a planetary eyepiece I don't see that as an issue in any way.
Highly recommended at the current selling price of about <$A170.
