Whether you wear glasses or not when you view the night sky, you’ll appreciate the exquisite optical performance and build quality of our 18mm Orion Long Eye Relief telescope eyepiece. With its luxuriously long 20mm eye relief, you can keep your eyeglasses on and still see the entire field of view in comfort. When observing without corrective lenses on, a supple pop-down rubber eyeguard helps position your eye properly to take in the entire eyepiece field-of-view.

This beautiful, fully multi-coated, 1.25” eyepiece delivers rich, high-contrast images across a 55° apparent field of view. Thanks to its design, the 18mm Long Eye Relief telescope eyepiece provides excellent correction so stars stay sharp and bright all the way to the edge of the visible field. Featuring five high-quality lens elements arranged in three groups, the 18mm Orion Long Eye Relief telescope eyepiece is more highly corrected than popular Plossl eyepieces.

With a moderate focal length of 18mm, this Long Eye Relief telescope eyepiece will provide pleasing views of almost any subject in the night sky. You can expect great performance when viewing the Moon, the brighter planets, and many deep-sky objects such as open and globular star clusters and bright nebulas. You can further enhance your views through this 18.5mm eyepiece with any 1.25” Orion eyepiece filter since its barrel is conveniently threaded for filter use.
