Excellent value

I bought a pair for my binoviewer. Not the most critical application but they are a good choice, not too heavy and small tops make eyeplacement easy. Ideal also for glasses wearers as the rubbers fold right down.The finish is excellent and the optics more than you might expect. Bright, sharp to the edge so you get the most from 55deg. Comfort and clarity trumps wide views at this price point..

Very well made eyepiece with excellent eye relief, making it easy to use/look through for inexperienced and advanced astronomers alike. Solid, weighty and good quality glass. Views better than expected for the price. Highly recommended!!

Maybe it's because the focal length hits the sweet spot on my 200p in regards to exit pupil, but the picture quality through this eyepiece is superb. It's really comfortable to use too and the design is elegant and it feels really well built. Much better than the supplied eyepieces.
