Edge-blackened optics and optimised baffles minimise internal reflections.

20mm eye-relief and twist-up rubber-rimmed eyecups - perfect for spectacle wearers.
Chromed barrels threaded to accept filters.
Weatherproof to JIS Class 4 standards.
Beautifully engineered eyepiece. Very comfortable, especially the twist-up eye relief adjustment. Extremely sharp view right across the field, which is just right.Highly recommend for any scope but if you have a fast scope eg Reflector at f5 or faster and have mid-range or telescope stock eyepieces, you will absolutely transform your scope with the XW series.
Bought this eyepiece because it has 20 mm which I need when I observe wearing eyeglasses. I have used it with a Tak FC-100, Vixen SD81S, Vixen A80M and Celestron C8 on moon, planets, double stars and DSOs. Performance is excellent, producing excellent sharpness and contrast, and aberrations are extremely well controlled. Also, the eyepiece has an excellent quality feel to it and is very comfortable to use. Highly recommended.
