TeleVue Nagler Eyepieces
Aside from their superb optics and stunning 82º apparent field of view, Nagler eyepieces feature an ingenious click-stop "instajust" eye guard. No matter the type, Naglers are a popular hit with amateur astronomers around the globe. All Nagler eyepiece have an eye-popping field of view, excellent eye relief, and incredibly sharp optics. They provide that "Space Walk" experience and are among the most highly coveted telescope accessories ever made.
To see the relative size difference between 50 degree and 82 degree eyepieces, lay a penny and a half dollar down on the table side by side. The difference is huge - the half dollar is almost three times the area of the penny! Al Nagler wanted to give his customers an experience that would be similar to looking at an object with the naked eye, except with a lot more magnification, and the 82 degree Naglers definitely hit the mark. After awhile, you will forget that you're looking through an eyepiece at all you'll be so fully immersed in the experience.
All Nagler eyepieces have blackened lens edges, anti-reflection threads and rubber eye guards for maximum contrast. Innovative features, such as adapter skirts for 2” focusers on larger 1.25” models and rubber grip rings were invented by Tele Vue. A 100% full field visual inspection on Tele Vue’s flat-field test instruments guarantees the performance of every Nagler eyepiece.
Type 4 Nagler Eyepieces
Tele Vue Nagler Type 4 Eyepieces are designed with all of the features savvy amateur astronomers have come to expect over the years, including that “Space Walk” 82 degree apparent field of view and quality optics that reveal super sharp, high contrast images. The Type 4 Nagler’s have about 18mm of eye relief, which makes them very comfortable to view through, whether you wear eyeglasses or not.
The unique “Instadjust” eye guard housing on all Type 4 Nagler eyepieces allows maximum eye relief for eyeglass wearers in the down position. Pulling the housing up will permit click-stop setting of the eye guard height, allowing for an ideal match between the pupils of your eye and telescope. With this much eye relief available, it is important to learn your own optimum “click stop” position.
If you don’t wear eyeglasses, start with the eyeguard housing pulled out all the way. You can fold the soft rubber eyeguard up or down, whichever is most comfortable for you. You may not see the full field with the eyeguard housing fully extended; just keep “clicking down” until you find the most comfortable position where you still see the entire field. You will also find that this system minimizes extraneous outside light, giving you the highest contrast when viewing faint objects. The generous eye relief also minimizes eye lens fogging due to eye moisture in cold weather.
Type 4 Nagler eyepieces are also Dioptrx compatible, allowing you to correct for near- or far-sightedness with this unique diopter system.
