The new 45° 70mm Binocular Telescope is the smallest and least-expensive binocular telescope on the market. At just over a foot in length, it is approximately half the size of the 45° 100mm Binocular Telescope, and at 8.5 lbs., is just 1/3 of the weight. For those with limited space, or needing easy portability, this new model is a great choice. Of course it also has Oberwerk's signature broadband multi-coatings on every lens surface, including the porro prisms and triplet objectives. Our finest 23.9mm (16x) fully multi-coated wide-angle (65° AFOV) eyepieces are included, and because of the industry-standard 1.25" helical focusers, your favorite telescope eyepieces can be used as well. 8mm eyepieces will provide 47x magnification in this binocular, which is the recommended limit. The built-in retractable glare shields minimize reflections.
Complete package price includes binocular, removable handle, aluminum-frame case, and 16x eyepieces. If you need a mount, choose the configuration below with Manfrotto 055XPRO3 tripod and Manfrotto MVH500AH head or Oberwerk wood tripod and Oberwerk 5000 head. To add a finder, order the BT-70-45 finder mount. Because accurate collimation is critical at higher magnifications, every Oberwerk binocular is collimated prior to shipping- so even at high magnifications, you'll enjoy perfectly merged images. 3-year Limited Warranty.
