ORION
Great for accurate polar alignment, the 4-element Plossl design is also well suited for off-axis guiders, where light gathering is minimal. Fully multi-coated lenses, 40-deg apparent field. LED-illuminated double crossline reticle has adjustable focus and brightness. SR-54 batteries included. 1.25" diameter.

Edge-On Planetary eyepieces bring flat-field performance to solar system viewing in the form of three high-magnification focal lengths. Each employs a sophisticated 7-element lens design reminiscent of exotic, high-priced oculars to provide a sharp focus all the way to the edge of their wide 55-degree apparent field of view. The barrel distortion and field curvature aberrations common in standard eyepiece designs are virtually gone. Edge-On Planetary eyepieces let you push the power, whether you're canvassing the lunar terminator or studying the Jovian cloud belts. The 7-element optics are fully multi-coated for high light transmission, and each eyepiece has 20mm eye relief for viewing comfort. Other nice touches: blackened lens edges, pop-down rubber eyeguards, and barrels threaded for 1.25" filters. Barrel diameter: 1.25".

These anodized, machined aluminum tubes provide extra focuser "back travel" sometimes needed to achieve focus with certain eyepiece/telescope combinations. More back travel is often needed for short-range terrestrial viewing or with use of a field flattener, coma corrector, or focal reducer lens. We offer 1.25" and 2" models, which fit 1.25" eyepieces and 2" eyepieces, respectively. Each adds 2" of length extension. Each also has two locking thumbscrews and is threaded for filters.

Tele Vue
Since we introduced our Plossls in 1980, they have won praise and patents, including a patent in Japan. TeleVue Plossls, designed by Al Nagler, have been a recognized benchmark of performance and value in the class of 50 degree apparent field of view eyepieces. While the Plossls may be our least expensive eyepiece line, they still enjoy the same care and attention to detail as our most expensive. While it's easy for other manufacturers to vie for the lowest price, TeleVue continues to believe that quality, performance and consistency will ultimately reward you with the most value for your dollar. Diffraction limited "on-axis" performance is a given. Using more expensive high-index glasses to reduce astigmatism and lateral color at the field's edge, TeleVue Plossls deliver sharper images than any other brand of 4 or 5 element "Plossl" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using TeleVue eyepieces. TeleVue Plossls feature full multi-coatings for gratest light transmission and contrast. Blackened lens edges and internal anti-reflection threads tweak the last bit of contrast for maximum image detail. The sharper field focuses faint star light into perceptible points and allows those with undriven mounts to gaze longer before repositioning the image.

Tele Vue
By limiting the field to 60 deg. (a Radian = 57.3 deg.) and establishing a uniform 20mm eye-relief, Tele Vue reworked the Nagler concept using the latest glass types to achieve optimum full field sharpness, freedom from distortion, freedom from ghosting (for critical planetary viewing) along with a unique adjustable eyeguard assembly which Tele Vue calls "Instadjust" Instadjust was developed from the need for proper eye position for non-eyeglass wearers. It is essential, since with Radian's long eye-relief, non-eyeglass wearers would easily tend to get too close to the eyepiece, resulting in vignetting the field, just as you would moving out from the exit pupil. The click-stop, Instadjust eyeguard permits fast, accurate positioning of the eye to the exit-pupil with maximum suppression of environmental stray light. Instadjust is topped off by a soft (for comfort and eyeglass protection) fold-down rubber eyeguard and protective cap. Usual Tele Vue features such as full multicoating, blackened lens edges, parfocalization, and grip-ring complement the Radian line.

ORION
Enjoy comfortably long eye relief, a wide 55-degree apparent field of view, and fully multi-coated, 6-element optics that include two elements crafted from special ED glass. "ED" stands for "extra-low dispersion," optical glass that boasts superior refractive properties compared to standard optical glass. The result is 20mm eye relief for every focal length, reduced chromatic aberration, and excellent image sharpness. Even the short-focal-length Epics sport nice, wide eye lenses, not small peep-holes! The series is parfocal, so little or no refocusing is needed when switching from one Epic eyepiece to another. Each eyepiece comes with two end caps and a durable plastic tube case. Barrel diameter, 1.25". Threaded for filters.

With most eyepieces, stars look sharp in the center of the field of view, but start getting fuzzy and flared toward the edge. To get better, "flat-field" performance, you have to pay big bucks for exotic ocular designs. Not anymore. Orion Edge-On eyepieces deliver remarkably flat fields -- pinpoint-sharp stars from the center to the edge of the viewing circle. And best of all, their price won't flatten your wallet! You'll be as amazed by the value as you are by the views. Their 5- or 6-element optical design eliminates field curvature for distortion-free images. And Edge-Ons are parfocal, so you can change eyepieces without refocusing. With their big eye lenses, fully multi-coated lens elements, long eye relief, generous fields of view, twist-up eyeguards, and 1.25" barrels threaded for filters, Edge-On eyepieces have the features and quality you'll appreciate. Get the eyepieces with a flat-field edge -- Orion Edge-Ons
