Massive 120mm objective lenses paired with premium Extra-Low Dispersion (ED) glass deliver breathtaking views of the night sky - bright, sharp, and rich with detail. The large aperture gathers an abundance of light, pulling out faint stars, intricate nebulae, sweeping star fields, and distant galaxies that smaller optics simply can't match.\n\u003c\/p\u003e\n\u003cp\u003e\n  ED glass technology aggressively reduces chromatic aberration and false color, resulting in cleaner edges, superior contrast, and natural color reproduction - even at higher magnifications. The BT 120mm comes ready to use with a pair of 62° 20mm Waterproof Eyepieces and accepts standard 1.25-inch interchangeable eyepieces, so you can tailor the magnification and field of view for any target - from wide-field Milky Way sweeps to detailed lunar and planetary sessions.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e120mm ED Objective Lenses:\u003c\/strong\u003e Massive 120mm aperture lenses with Extra-Low Dispersion glass deliver exceptional light-gathering power with high contrast and outstanding color correction.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Chromatic Aberration:\u003c\/strong\u003e Premium ED glass significantly minimizes false color and chromatic aberration around bright objects, producing cleaner, crisper images.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImmersive Two-Eyed Observing:\u003c\/strong\u003e Giant binocular design provides a natural, relaxed viewing experience that makes long observing sessions more comfortable and engaging than single-eye telescopes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchangeable 1.25-Inch Eyepiece System:\u003c\/strong\u003e Accepts standard 1.25-inch eyepieces, allowing flexible magnification choices for deep-sky, lunar, planetary, and terrestrial targets.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded 62° 20mm Waterproof Eyepieces:\u003c\/strong\u003e Ships with a matched pair of Explore Scientific 62° 20mm Waterproof Eyepieces for a wide, comfortable field of view right out of the box.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuilt for Mounted Use:\u003c\/strong\u003e Designed for use with a heavy-duty mount - pairs optimally with the Explore Scientific U-Mount and Tripod for smooth, stable movement during extended sessions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAstronomical and Terrestrial Use:\u003c\/strong\u003e Performs brilliantly on star clusters, nebulae, galaxies, and open clusters, as well as daytime terrestrial subjects.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLimited Warranty:\u003c\/strong\u003e Backed by the Explore Scientific limited warranty for peace of mind on your investment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Explore Scientific - a trusted name in premium optical instruments for amateur and serious astronomers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eExplore Scientific BT 120mm ED Giant Binocular\u003c\/li\u003e\n  \u003cli\u003ePair of Explore Scientific 62° 20mm Waterproof Eyepieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhy You'll Love It\u003c\/h2\u003e\n\u003cp\u003e\n  The BT 120mm ED Giant Binocular is a showpiece instrument that transforms every observing session into an unforgettable experience.
