The BT-100XL-ED is the second largest and most powerful in the XL Series, yet weighs a mere 12.5 lbs! With 100mm FK-61 ED objectives, 24mm of clear prism aperture, and a lightweight magnesium alloy body (waterproof and nitrogen-filled), 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 (40x) eyepieces. The ED objectives greatly minimize chromatic aberration up to 80x magnification (7mm eyepieces). 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. Not only is the BT-100XL-ED the highest-quality binocular telescope on the market, it’s 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. Every BT-100XL-ED is tested and tuned to perfection prior to shipping, with collimation certified to 140x. 3-year Limited Warranty.
