Orion 1.25" Edge-On Planetary Eyepiece Expansion Set

Enjoy viewing the vast wonders of the solar system with the Orion Edge-On Planetary Eyepieces! This Edge-On Planetary Eyepiece Expansion Set features impressive flat-field performance in three focal lengths. Each eyepiece uses an advanced lens design with 7 elements. You may recall similar designs in much more expensive high-end eyepieces.Orion makes a sharp image and 55-degree field of view accessible without breaking your budget.

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 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 lens edges, pop-down rubber eyeguards, and barrels threaded for 1.25" filters. The Starter Set of Edge-On Planetary Eyepieces includes 14.5mm, 9mm, and 5mm focal lengths.
