    en.wikipedia.org/wiki/Televue

    The introduction of the original Nagler 13mm Type 1 in 1982 with its wide field of view and an equally high price soon made their mark. Using different combinations of lenses of different types of high index optical glasses, the eyepieces produce, respectively, a 50°, 62°, 68°, 72°, 82°, 100°, and 110° apparent field-of-view. Tele Vue ...
