Orion 5mm Edge-On Eyepiece

Eyepiece close out. Was $99, now only $69.

The Orion 5mm Edge-On Planetary eyepiece brings flat-field performance and a comfortable 20mm of eye relief to solar system viewing. 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.

  • 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
  • Priced around $100 apiece, Edge-Ons won't have you "on edge" financially!

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.
