The BT-100XL is the non-ED version of the world’s finest and most-powerful binocular- the BT-100XL-ED. While that model’s ED objectives almost completely eliminate CA (chromatic aberration, or false-color fringing), the non-ED BT-100XL has minimal CA at magnifications as high as 80x. Other than that, you get all the features and performance of the BT-100XL-ED, at a much lower price! For all but the optical perfectionist, the BT-100XL is all the binocular you’ll need. With their lightweight magnesium alloy bodies, the XL Series sets a new standard for image quality AND portability. A binocular of this quality deserves great eyepieces, so we include our finest 70° AFOV 14mm (40x) eyepieces, which normally sell for $250/pair. These eyepieces are not threaded for use with filters, but because of the industry-standard 1.25″ helical focusers, your favorite telescope eyepieces can be used as well. With the widest IPD range of any binocular on the market (50-80mm), even small children can view through both eyepieces.
Other features include a Picatinny rail handle (for mounting a wide variety of finders or laser pointers) and extendable glare shields. Available in your choice of a speckle-finish “Big Eyes” Gray or a lustrous “Luna Pearl” White, with black-anodized trim. Our exclusive heavy-duty aluminum-frame case is included. Recommended mounts include the Oberwerk 5000 tripod/head, or the Oberwerk TR3 hardwood tripod with carbon-fiber elevator with either the Oberwerk 5000 head or the Manfrotto Nitrotech head. Every Oberwerk binocular is tuned to perfection prior to shipping- so even at extreme magnifications, you’ll enjoy perfectly merged images.
