    The Explore Scientific BT-150 ED Giant Binocular is a large-aperture astronomy binocular telescope for observers who want the ultimate two-eyed deep-sky experience. Its 150mm ED (extra-low dispersion) glass objectives gather enormous amounts of light, revealing faint nebulae, globular clusters, and galaxies with the bright, three-dimensional realism that only large binoculars for stargazing deliver. The 45° angled eyepieces keep long observing sessions comfortable, and the interchangeable 1.25" eyepiece holders let you tune magnification for sweeping star fields or detailed views.

    Who it's for

    Serious amateur astronomers and deep-sky observers who want maximum aperture in a comfortable, immersive binocular-telescope form factor.

    Key features

    • 150mm ED objective lenses for exceptional light-gathering and contrast
    • 45° angled viewing for comfortable overhead observing
    • Interchangeable 1.25" eyepieces to change magnification
