Our newest and largest XL Series Binocular Telescope features 5″ apochromatic (FCD100 / FK-61 triplet) objectives, with a relatively-short 650mm focal length. 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 silver anodized trim, it’s also quite attractive. Mount it on the gorgeous Oberwerk TR3 hardwood tripod, with the Oberwerk XL Fork Mount, and you’ll have the ultimate instrument for binocular astronomy. Need a tripod with a crank-up elevator? We can configure the Manfrotto 161MK2B with your choice of the NitroTech 612 head or Oberwerk XL Fork Mount.
The BT-127-XL-SD includes our premium 30x (22mm) 70° AFOV eyepieces. 46x (14mm) and 93x (7mm) are also available. The included heavy-duty case has wheels on one side for easy transport.
