Celestron 93435 Luminos Eyepiece - 2 in., 31 mm. Description

The Luminous series eyepieces offer a wide 82º field of view in both high power and low power models, allowing you to make the most of your telescope, whether you own a short, fast refractory or a Celestron EdgeHD telescope. The optical set consists of six or seven elements (depending on the model) and is fully multi-coated for crisp, sharp views. All six Luminous eyepieces are par focal, which means you can switch out eyepieces during observing sessions with little or no additional focusing required.

The Luminous eyepiece body is made of polished and anodized aluminum. A rubber grip runs around the equator of the eyepiece, giving you a secure grip and an easy method for raising and lowering the retractable eye cup. Simply twist the rubber grip to adjust the height of the eye cup. The insert barrel is threaded to accept filters.
