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.  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 either the RP OPTIX T3 tripod/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- astronomy072013-1so even at high magnifications, you’ll enjoy perfectly merged images. 3-year Limited Warranty.
