Orion 3 mm Edge-On Planetary Eyepiece
Orion 3 mm Edge-On Planetary Eyepiece
The 3 mm Orion Edge-On Planetary Eyepiece brings flat-field performance to solar system viewing in the form of 3 high-magnification focal lengths. Each employs a sophisticated 7-element lens design to provide a sharp focus all the way to the edge of their wide 55° apparent field of view. The barrel distortion and field curvature aberrations common in standard telescope eyepiece designs are virtually gone.
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 optics are fully multi-coated for high light transmission, and each eyepiece has 20 mm eye relief for viewing comfort. Other nice touches: blackened telescope lens edges, pop-down rubber eye guards, and barrels threaded for 1.25" filters.
