The Oberwerk BT-127XL-SD Binocular Telescope is the company’s newest and largest XL Series Binocular Telescope. It features 5″ apochromatic (FCD100 / FK-61 triplet) objectives, with a relatively-short 650mm focal length.
As the Oberwerk team notes, “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.”
The BT-127-XL-SD includes Oberwerk’s 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 prior to shipping, with collimation certified to 163x. 3-year Limited Warranty.
Recommended tripods are the Oberwerk TR3 hardwood tripod or the Manfrotto 161MK2B, which has a crank-up elevator. Either tripod can be configured with the Oberwerk XL-280 Fork Mount or Manfrotto 612 NitroTech Head. Fully-automated “go-to” operation is available using the iOptron AZ Pro.
