If you are passionate about planet observing then we've got just the eyepieces for you. Our Edge-On Planetary eyepieces bring flat-field performance to solar system viewing in the form of three high-magnification focal lengths. These 3mm, 6mm, and 12.5mm eyepieces employ 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-degree apparent field of view. The barrel distortion and field curvature aberrations commonly seen 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 optics are fully multi-coated for high light transmission, and each eyepiece has 20mm eye relief — exceptional for such short focal lengths! — for extreme viewing comfort. Other nice touches: blackened lens edges for improved contrast and glare prevention, pop-down rubber eyeguards, and barrels threaded for 1.25" filters. The Planetary series is parfocal, so eyepieces can be swapped without the need for refocusing.

Sharpen up your views of the planets and Moon with our high-power Edge-On Planetary eyepieces. At less than $100 apiece, they won't have you "on edge" financially! Barrel diameter: 1.25"
