Oberwerk BT-70XL-ED
Oberwerk BT-70XL-ED
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 1.25″ 70° AFOV 14mm (28x) eyepieces. The ED objectives will deliver chromatic aberration-free views up to 56x magnification (7mm eyepieces). With the widest IPD range of any binocular on the market (50-80mm), even small children can view through both eyepieces. Focal Lenght 390mm.
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.
