Orion 42mm DeepView 2" Long Eye Relief Eyepiece with 52 Degree Wide Field of View.

The Orion 42mm DeepView Eyepiece provides the brightest and sharpest images of deep-space objects with low power and a wide field of view. It features anodized aluminum housings and a 3-element lens design with multi-coatings for efficient light transmission. Eye relief is 20mm - a welcome spec for eyeglass wearers - and the rubber eyeguards fold down out of the way if desired.

Apparent field of view for the 42mm is a generous 52-degree. Delightfully free of pincushion distortion and chromatic aberration, this eyepiece will impress even the seasoned deep-sky observer. The barrel is threaded to accept 2" filters.
