Al put his lifelong love of amateur astronomy to work as a professional optical designer in 1958. But, it was his involvement in designing NASA lunar landing simulators (as seen in the movie “Apollo 13”) that most directly influences Tele Vue products of today. Al wanted his own observing equipment to deliver that seemingly limitless vista created for the astronauts. Producing wide, full-field sharpness and high contrast images are the keys.

Al’s “Nagler” series heralded its own revolution in eyepieces. Called “remarkable” by the author of “Telescope Optics”, it has an 82° apparent field, and 10 times the field sharpness of any previous eyepiece. Nagler eyepieces approached the realization of Al’s dream for “spacewalk” viewing, even more so with the long eye relief Nagler Type 4 models, long focal length Type 5 models, and short focal length Type 6 models. The next generation Nagler, Al’s son David (full time at Tele Vue Optics for more than 25-years and currently company President) took the next step in the “spacewalk” experience by laying the conceptual ground work for a 100° eyepiece to be designed by Al’s in-house protégé Paul Dellechiaie. The result is everything a Tele Vue eyepiece represents. It’s the Tele Vue Ethos.

Also, look at the celebrated Panoptic eyepieces for “tack-sharp,” low power, 68° fields. And, the 72° Delos series and 62° DeLite eyepieces both with 20mm eye relief, offer the most performance possible for eyeglass wearers. These, along with many other long eye-relief Tele Vue eyepieces accept DIOPTRX, the unique optical “missing link” between you and your equipment. It corrects your eyesight astigmatism so you can replace your eyeglasses for the best possible visual experience. Planetary enthusiasts can enjoy the Nagler Zoom with a constant 50° field and parfocal, 3-6mm focal length zoom range.
