Tele Vue 40mm Plossl 1.25" Eyepiece.
Ways to Save
Specially for eyeglass wearers, Tele Vue included a long eye relief 40mm focal length in the series with a 43 degree apparent field. Like the 55mm, its focal plane is at the barrel edge for maximum field in the 1 1/4" format.
The Al Nagler eyepiece design that laid the foundation for the Tele Vue reputation.
Since their introduction, Tele Vue Plossls have been a recognized benchmark of performance and value in the class of 50 degree apparent field of view eyepieces. With noticeably less astigmatism and lateral color at field's edge, they deliver sharper images than any other 4 or 5 element "Plossl". For a bit more than generic brands, you can own a genuine Tele Vue Plossl. Remember, you'll always be happy with the best.
Add full multicoatings, blackened lens edges, parfocalization, anti-reflection and filter threads, saftey undercuts, and rubber eyeguards resulted in contrast, sharpness, and quality levels that launched the Tele Vue "spacewalk" quest.
