The Explore Scientific BT-120 Giant Binoculars bring the power of a double refractor telescope to binocular viewing, providing stunningly bright and detailed images for both astronomy and terrestrial observation. Featuring an enormous 120mm objective diameter and 660mm focal length, these binoculars reveal craters on the moon, planets, bright deep-sky objects, and distant terrestrial landscapes with impressive clarity.
Designed for comfort and extended use, the 45-degree viewing angle, soft silicone eyecups, and fine helical individual focusing allow fatigue-free observation. Each eyepiece offers 15mm of long eye relief, and included 62° 20mm LER eyepieces deliver a wide apparent field of view, with interchangeable 1.25” plug-in options for magnification flexibility. Optional color and nebula filters can be used to enhance astronomical observation.
The BT-120 binoculars are built for durability, with a robust magnesium housing that is sealed and filled with nitrogen, providing waterproof and fog-proof performance in any condition. Extendable dew caps prevent lens condensation, and a central carrying handle ensures secure transport and tripod assembly. Multiple tripod connection options are available, and for optimal stability, the optional Explore Scientific U-Mount with field tripod is recommended.
With professional-grade coatings on all optical surfaces and precise brass compression ring clamps for eyepiece alignment, the BT-120 offers bright, vivid, and tilt-free images. These giant binoculars provide an unparalleled, immersive viewing experience for astronomy enthusiasts, birders, and nature observers seeking exceptional clarity and comfort.
