BT 150mm ED Giant Binocular

The Explore Scientific BT 150mm ED Giant Binocular is the pinnacle of binocular astronomy, delivering an extraordinary observing experience through two massive 150mm optical systems—one dedicated to each eye. Combining exceptional light-gathering power with premium Extra-Low Dispersion (ED) glass, the BT 150mm ED produces breathtaking views filled with remarkable brightness, sharpness, and immersive depth that simply cannot be replicated with conventional binoculars or a single telescope. Each 150mm objective gathers an incredible amount of light, revealing dense star fields, richly detailed open clusters, expansive nebulae, and brighter galaxies with impressive clarity. Observing with both eyes creates a more natural and comfortable viewing experience, allowing you to appreciate the night sky with greater depth and less eye fatigue during extended observing sessions. Premium ED glass enhances this remarkable optical system by significantly reducing chromatic aberration and false color around bright, high-contrast objects. The result is cleaner edges, improved contrast, more accurate color reproduction, and sharper detail when observing the Moon, planets, bright stars, and terrestrial subjects. The BT 150mm ED comes ready for its first night under the stars with a pair of Explore Scientific 62° 20mm Waterproof Eyepieces, while its interchangeable 1.25-inch eyepiece design allows you to tailor magnification and field of view to match virtually any observing target. As an instrument of this size, the BT 150mm ED is designed exclusively for mounted use. Pairing it with the Explore Scientific U-Mount and Tripod provides the stability and smooth movement needed to comfortably navigate the sky while unlocking the full potential of this exceptional giant binocular system. Whether you're sweeping through the Milky Way, resolving rich open clusters, studying intricate lunar landscapes, or exploring bright nebulae and galaxies, the Explore Scientific BT 150mm ED Giant Binocular delivers one of the most immersive and rewarding observing experiences available. Tripod and U-Mount shown in images is not included.
