    The Explore Scientific BT-120 ED Giant Binocular is a large-aperture astronomy binocular that turns two-eyed observing into a serious deep-sky instrument. Its 120mm ED (extra-low dispersion) glass objectives gather a huge amount of light, so star clusters, nebulae, and the Moon show bright and sharp with true, natural depth — the immersive experience serious binoculars for stargazing are loved for. The 45° angled eyepieces make long sessions comfortable, and the interchangeable 1.25" eyepiece holders let you dial in the right magnification for wide star fields or closer looks.

    Who it's for

    Intermediate and serious stargazers who want maximum light-gathering for deep-sky objects in a comfortable, immersive binocular-telescope form factor.
