The highly-acclaimed Oberwerk BT-100-45 features 45° viewing and a strong and smooth fork mount, which together provide comfortable astronomical viewing from horizon to zenith. Of course the 45° 100mm Binocular Telescope also has Oberwerk’s signature broadband multi-coatings on every lens surface, including the triplet objectives and massive Porro prisms. 25x wide-angle eyepieces are included, but because of the industry-standard 1.25″ helical focusers, your favorite telescope eyepieces can be used as well. The optical train is based on the same proven design as the original 25/40×100 Long-Range Observation Binocular. For almost two decades, this was considered the world’s most powerful binocular, until it was edged out by our high-tech BT-100XL-ED. But the old-school BT-100-45 remains a popular choice- mounted on the included fork mount and hardwood tripod, it’s a majestic instrument at an affordable price.
The BT-100-45 is finished in a lustrous “Luna Pearl” White. Complete package price includes binocular, 7x50mm finder-scope, aluminum carrying case, American-made TR3 hardwood tripod, paint-matched aluminum fork mount, and 25x oculars. The tripod is available in your choice of hardwoods and finish colors. Custom laser-engraving is also available. If you need easy crank-up height adjustment, take a look at our Manfrotto 161MK2B tripod option. Need easy mobility? Just add the Manfrotto 181B Auto-Dolly. Because accurate collimation is critical at higher magnifications, every Oberwerk binocular is tuned to perfection prior to shipping- so even at the upper limit of magnification, you’ll enjoy perfectly-merged images. 3-year Limited Warranty.
