Description
The fixed magnification LER (Long Eye Relief) Eyepiece is a great addition to your Celestron spotting scope, especially if you participate in shooting sports. With a generous 32 mm of eye relief, you’ll be able to look through the eyepiece without sacrificing your shooting position or removing protective eyewear. The wide field of view helps you bring subjects into the field of view quickly. The larger viewing area also makes it easier to follow subjects as they move. When used for target shooting, this eyepiece enables you to see to the left and right of your target and identify changes in the wind when reading mirage.
XLT Optical Coatings
Celestron’s proprietary XLT coatings the eyepiece coupled with the spotting scope delivers bright, razor sharp images with amazing detail. XLT coatings, developed for our observatory-grade telescopes, increase light transmission through the optical path and deliver crisp, high contrast images with outstanding resolution.

Waterproof and Nitrogen Purged
