The Alpen Apex XP 10x50 ED Waterproof Binoculars pair a wide field of view with a large 50mm ED (extra-low dispersion) objective lens, making them a versatile choice for stargazing, wildlife viewing, and general outdoor use. The bigger 50mm lenses gather more light than a standard 42mm pair, which makes a real difference when you're scanning the night sky or watching for movement at dusk.

ED glass helps keep bright stars and high-contrast edges free of the color fringing you get with lower-end optics, so views stay crisp and true-to-color. Fully multi-coated lenses and phase-corrected BAK4 roof prisms add extra brightness and contrast.

Who It's For

A solid pick for beginners who want one pair of binoculars that works well for both casual astronomy and daytime outdoor use like birding or hiking. New to using binoculars for astronomy? Our guide on binoculars vs. a telescope for beginners walks through what to expect.
