The history of this manufacturer of telescopes and accessories begins in the late seventies. Al Nagler, an optical designer and amateur astronomer, founded the company TeleVue. Although it started small, the company quickly developed into one of the leading manufacturers in this field.
TeleVue is particularly well known for its eyepieces. The Nagler, Delos and Ethos series are considered some of the best eyepieces on the market for astronomical equipment. The new DeLite series also offers high quality eyepieces at an affordable price, ideal for those on a budget.
The type 5 eyepieces with 20, 26 and 31 mm are ideal for short focal length Newtonian telescopes, even on the 20" f/4 stars are absolutely point-like almost to the edge.
The Nagler zoom offers the best possible imaging quality and keeps up with the best planetary eyepieces in direct comparison. And compared to the Ortho's it offers four focal lengths, a wider field of view and a much more comfortable viewing experience.
