Improve the quality of view in any telescope with an 18mm Orion Epic II ED eyepiece! This 1.25” petite performer features 6 individually polished lenses including 2 elements of high-quality “extra-low dispersion” ED optical glass for stunning, true-color views. Thanks to the use of ED glass elements, the 18mm Epic II ED telescope eyepiece produces views of exquisite quality which are delightfully free of chromatic aberration, or color distortion, which plagues many other eyepiece designs. 

With a wide 60° apparent field of view, the Orion 18mm Epic II ED is a great eyepiece choice for viewing objects within our solar system, as well as many deep-sky objects. With a moderate 18mm focal length, this Epic II ED telescope eyepiece is great for medium-magnification views of the Moon, planets, and many bright nebulas and star clusters. Its design of 6 lens elements arranged in 3 groups provides excellent correction and definition, yielding sharp stars across the entire field. The 18mm telescope eyepiece’s 13mm eye relief makes it comfortable to use - no need to squint!

The 18mm Epic II ED eyepiece’s easy-grip, rubberized housing features a convenient, twist-up rubber eyeguard to help properly position your eye to see the entire field-of-view. Its internally blackened barrel helps minimize glare and reduce “ghost” images. A safety channel on the eyepiece barrel exterior helps keep the 18mm Epic II ED securely installed in telescope focusers and diagonals. To enhance or optimize your views further, you can install any 1.25” Orion eyepiece filter on the 18mm Epic II ED eyepiece, as its 1.25” barrel is threaded for filter use.

All Orion Epic II ED telescope eyepieces are parfocal, so you can swap this 18mm model out for a different focal length Epic II ED eyepiece and enjoy the view without making major focus adjustments.
