The 5mm Orion Edge-On Planetary Eyepiece brings flat-field performance to solar system viewing. The eyepiece utilizes a chic 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. Virtually gone are the field curvature aberrations and barrel distortion common in standard telescope eyepiece designs.

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 include pop-down rubber eyeguards, blackened telescope lens edges, and barrels threaded for 1.25" filters. The barrel diameter is 1.25".
