The 13mm Tele Vue Nagler debuted in 1980 and won wide acclaim among amatauer astronomers. Tele Vue produced this eyepiece until 2001, when the 13mm Type 6 replaced it. // Astronomy: James Forbes
If you enjoyed “The life and times of Al Nagler” that appeared in the April 2013 issue of Astronomy, I think you’ll like the first story I wrote about Nagler and Tele Vue Optics — the company he founded. That article, “The eyepiece that changed observing,” focuses more on the technological contributions of the man whose greatest invention revolutionized amateur astronomy. It appeared in our December 2005 issue, and you can read it below.
