Our newest and largest XL Series Binocular Telescope features 5″ apochromatic (FCD100 / FK-61 triplet) objectives, with a relatively-short 650mm focal length, and 27mm of clear prism aperture. The BT-127XL-SD was designed to be the highest-performing production binocular on the market, without regard to cost. Even with two 5″ triplet objectives and massive prisms, magnesium-alloy construction makes it remarkably-lightweight at just 24.5 lbs. With its unmatched image quality, we think it’s a much more practical alternative to the world’s largest 150mm binoculars, which are very heavy, very expensive, and difficult to mount. Finished in iridescent “Luna Pearl” White with gold-anodized trim, it’s also quite attractive.
The BT-127-XL-SD includes our premium 14mm (46x) 70° AFOV eyepieces. 30x (22mm) and 93x (7mm) are also available. The included heavy-duty case has wheels on one side for easy transport.
Every BT-127XL-SD is tested and tuned to perfection prior to shipping, with collimation certified to 163x. 3-year Limited Warranty.
