Orion Edge-On Planetary Telescope Eyepieces
  • High-magnification 1.25" eyepieces designed for exceptional planetary and lunar viewing
  • Flat field design ensures sharp focus all the way to the edge of their wide 55-degree apparent field of view
  • Barrel distortion and field curvature commonly seen in standard eyepiece designs are virtually gone
  • Each eyepiece has long 20mm eye relief for comfortable viewing even with eyeglasses on
  • Amazingly affordable Edge-On Planetary eyepieces won't leave you "on edge" financially!

3mm Orion 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-deg apparent field of view. The barrel distortion and field curvature aberrations common in standard telescope 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 telescope lens edges, pop-down rubber eyeguards, and barrels threaded for 1.25" filters. Barrel diameter: 1.25".
