| Includes continuously adjustable height eyeguard with index marks. Parfocal with all Tele Vue 1¼" eyepieces. | |
| Nagler Type 6 The 7-element, Nagler Type 6 design is based on the original patented Nagler design. This new 7-element design update for the short focal length Nagler deserves its... | |
| Nagler Type-4 Eyepieces Applying the experience of the Radian development to the 82° Nagler series, yielded more contrast, reduced pincushion, more true field, longer eye-relief, and fewer elements. With added... | |
| Satisfy your visual cravings for naturally sharp, high contrast images with Tele Vue eyepieces. "Your eyepiece is half the telescope, use the best - Tele Vue", says Jack Marling (founder... | |
| Size, weight and performance make the 19mm an ideal mid power chioce. Ideal "soul-mate" to Bino Vue. Parfocal with 15mm and other smaller Plössls and Naglers. | |

| Tele Vue 102 Discontinued as of October 1, 2011 We suggest you consider the NP-101 as a worthy replacement. While more expensive, its 4-element Petzval design (540mm, f/5.4) yields 2.6x... | |
| The 10mm is parfocal with the 13mm ETHOS. Its 59mm rubber grip diameter makes this model usable in binocular viewers - for most people. | |
| The 11mm Nagler Type 6 slots in perfectly between the 13mm and 9mm Type 6s and makes a perfect companion to the 7mm. Nagler Type 6 The 7-element, Nagler Type... | |
| The 16mm Nagler Type 5 is a scaled down version of the "king of the field," 31mm. The Type-5 16mm is a smaller, lighter (0.45 lbs.), 1¼" only, 6-element design... | |
| The 17mm ETHOS is an ideal complement to the 31mm Nagler Type-5. They are parfocal (both have focus locations about 3/8" above shoulder) and the 31mm Nagler Type-5 has exactly... | |
| The 2-4mm Nagler Zoom is recommended for fast, high performance scopes of 800mm focal length or shorter, such as the Tele Vue-60. It has click-stops every half-mm. Why Are There... | |
| The 2.5mm eyepieces provide a natural 1.4x progression in power from the 3.5mm. You don't have to sacrifice field in order to gain sharpness and power. And, you're not limited... | |
| The 20mm Type 5 is a compact 1-pound, 2" eyepiece that fills out the eyepiece line and is a worthy successor to the heaviest commercial eyepiece ever produced: the Nagler... | |
| The 21mm focal length completes the logical set of 21mm/13mm/8mm and nicely juxtaposes the 17mm/10mm/6mm combination. Each step within these two sets approaches a 3x field area gain. The 21mm's... | |
| The 25mm, 20mm, 15mm, 11mm and 8mm Plössls round out the focal lengths for various observing from deep sky to planetary. They work best with Tele Vue Powermates to effectively... | |
| The 3.5mm Nagler Type 6 is a natural progression of 1.4x power steps from 7mm and 5mm Naglers. You don't have to sacrifice field in order to gain sharpness and... | |
| The 32mm Plössls, with its larger 50° apparent field, will deliver the same true field as the 40mm but with higher magnification. The 32mm is parfocal with the shorter focal... | |
| The 35mm has a large true field with plenty of eye relief for eyeglass wearers. When combined with a Paracorr to correct the coma of an f/4.5 Newtonian, performance is... | |
| The 41mm Panoptic eyepiece is a big brother to the 24mm Panoptic (largest 1.25" field). With its 46mm field stop, the 41mm Panoptic delivers the largest 2" field possible. An... | |
| The 55mm focal length has the largest true field possible for 2" eyepiece holders -3 times the true field area of any 1¼" eyepiece. The focal plane is placed at... | |
| This is a somewhat smaller, lighter and more powerful version of the celebrated 31 Nagler Type 5. Why? Because customers such as Tom Dietz, from the Smithsonian, are pests! :-)... | |
| This model has click stops every mm. Why Are There 3 Types of Naglers? To achieve the full magnification range over 82° apparent field of view requires two types: Nagler... | |
| This Sky & Telescope "Hot Product" is designed to produce the largest true field possible in a 1¼" eyepiece. (Its 27mm field stop is the same as the 32mm Tele... | |
| We have not specifically endorsed the 13mm Ethos for Bino-Vue use because of the large diameter barrel. Even so, we were advised by Mike Harvey at the Winter Star Party... | |
| With 110°, the Ethos-SX has 21% more AFOV area than the 100° Ethos design. This permits a nice 62% power increase from a 6mm Ethos, while retaining 68% of its... | |
| With the 31mm, the unique 6-element design using four exotic glasses, maintains the contrast advancement of the Type 4s while achieving a true field area 82% larger than the 22mm... |
