The Vixen LVW Series, 1.25" to 2", eyepieces use premium Lanthanum glass to minimize aberrations. They employ a 5-group, 8-element design for a wide 65° apparent field of view. 68° Apparent Field, Long Eye-relief, Incredibly versatile eyepiece..
1.25 diameter fits all scopes.  One of the very Best Values in eyepieces.
With the best-designed and first commercially available 100° or 110° eyepieces, TeleVue hit a home run with the Ethos eyepieces.  Superb clarity, color-fidelity, edge-of-field sharpness and light transmission combine with extremely low distortion and comfortable eye relief to produce what many call the "ultimate" eyepiece.  Ethos eyepieces allow large fields of view to be seen at higher powers, and that really brings out the magnificence of the cosmos in any scope.  TeleVue calls it "The Majesty Factor", and we would have to agree.
