Orion Edge-On Planetary Telescope Eyepie

High-Power, Flat-Field Design for Better Planet Study.

Mid- and high-magnification 1.25" eyepieces designed for exceptional planetary and lunar viewing Flat field design ensures sharp focus out to the edge of their wide 55-degree apparent field of view Barrel distortion and field curvature commonly seen in standard eyepiece designs are gone Each eyepiece has long 20mm eye relief for comfortable viewing even with eyeglasses on Orion Edge-On Planetary Telescope Eyepieces. Amazingly affordable Edge-Ons won?t have you "on edge" financially!

Edge-On Planetary eyepieces bring flat-field performance to solar system viewing in the form of six medium- and high-magnification focal lengths. Each employs a sophisticated 7-element lens design reminiscent of exotic, high-priced oculars. This design renders an optically flat image that's sharply focused from center to edge of the 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 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 1.25" barrels threaded for filters.
