BT 120mm ED Giant Binocular

The Explore Scientific BT 120mm ED Giant Binocular delivers an immersive two-eyed observing experience with the light-gathering power and optical performance serious astronomers demand. Featuring massive 120mm objective lenses paired with premium Extra-Low Dispersion (ED) glass, these giant binoculars produce bright, high-contrast images with outstanding sharpness, natural color, and impressive detail across a wide range of astronomical and terrestrial subjects. The large 120mm aperture collects an abundance of light, revealing fainter stars, richer star fields, and greater detail in nebulae, galaxies, and open clusters. Whether you're sweeping through the Milky Way or examining intricate lunar features, the BT 120mm ED delivers breathtaking views that are both immersive and exceptionally crisp. Premium ED glass further enhances the experience by significantly reducing chromatic aberration and false color around bright, high-contrast objects. The result is cleaner edges, improved contrast, and more accurate color reproduction, allowing the optical system to perform at its best—especially when using higher magnifications. The binocular comes ready to observe with a pair of Explore Scientific 62° 20mm Waterproof Eyepieces, providing a wide, comfortable field of view right out of the box. Because the binocular accepts interchangeable 1.25-inch eyepieces, you can easily customize magnification to suit everything from expansive deep-sky vistas to detailed lunar and planetary observations. Due to its size and weight, the BT 120mm ED is designed for mounted use. Pairing it with the Explore Scientific U-Mount and Tripod provides the stability and smooth movement needed to fully appreciate the remarkable optical performance these giant binoculars are capable of delivering.
