The BT-70XL-ED, the smallest of the XL Series, is the least-expensive ED binocular telescope on the market.
The BT-70XL-ED is the smallest member of the XL Series family and is the least-expensive ED binocular telescope on the market. With 70mm FK-61 ED objectives, 24mm of clear prism aperture, and a lightweight magnesium alloy body, this binocular telescope 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 (25x) 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. The ED objectives will deliver chromatic aberration-free views up to 50x magnification (7mm eyepieces). With the widest IPD range of any binocular on the market (50-80mm), even small children can view through both eyepieces.
The handle is actually a Picatinny rail, which can be used to directly mount a wide variety of finders or laser pointers. Not only are the XL Series the highest-quality binocular telescopes at anywhere near their relatively-low prices, they are also quite attractive! Available in your choice of a speckle-finish “Big Eyes” Gray or a lustrous “Luna Pearl” White, both featuring red-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 and Oberwerk 5000 head. Every Oberwerk binocular is tuned to perfection prior to shipping- so even at extreme magnifications, you’ll enjoy perfectly merged images.
