The Explore Scientific G400 Series 10x50 Waterproof Binoculars pair 10× magnification with large 50mm objectives for bright, wide-field views — a great choice for stargazing as well as birding and outdoor observation. The bigger 50mm lenses gather more light than a 42mm pair, so images stay bright at dusk and under the stars.

BAK-4 roof prisms with phase and dielectric coatings deliver sharp, high-contrast, true-color images, and the nitrogen-purged, waterproof housing keeps them fog-free in any weather.

Who it's for

Stargazers and nature watchers who want extra light-gathering and reach, and don't mind a little more size and weight for brighter low-light views. Comparing binoculars to a telescope? See our guide to astronomy binoculars vs a telescope.

Frequently asked questions

Why choose 10×50 over 10×42?
The larger 50mm objectives gather more light, giving brighter images in low light and under the stars — at the cost of a bit more size and weight.

Are these good for astronomy?
Yes — 10×50 is a classic astronomy binocular size, bright enough to show star clusters, the Milky Way, and lunar detail, while still handholdable for short sessions.

Can I mount them on a tripod?
Yes — most full-size binoculars, including these, accept a tripod adapter for steady, extended viewing.
