Description

Assuming that you don't subscribe to the misconception that strong magnification gives better views of deep-sky objects, then the Orion DeepView 28mm 2" Telescope Eyepiece should excite you. Why? Because the brightest and sharpest images of deep-space objects are obtained with low power and a wide field of view, and DeepView 2" eyepieces deliver just that.

DeepView telescope eyepieces feature anodized aluminum housings and a 3-element lens design with multi-coatings for efficient light transmission. Eye relief of each DeepView telescope eyepiece is a long 20mm - a welcome spec for eyeglass wearers - and the rubber eyeguards fold down out of the way if desired. The 28mm DeepView eyepiece features a generous 56-degree apparent field of view. Delightfully free of pincushion distortion and chromatic aberration, DeepView 2" telescope eyepieces will impress even the seasoned deep-sky observer. The barrels are threaded to accept 2" eyepiece filters.
