Binocular telescope from Oberwerk in Luna Pearl White with premium eyepieces (better field of view and magnification than standard bundle). Was just re-collimated by Oberwerk. Has a few very minor paint dents that were present brand new and are considered normal out of the factory.
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 48x magnification in this binocular, which is the recommended limit. The built-in retractable glare shields minimize reflections. Available in your choice of “Luna Pearl” White or “Big Eyes” Gray.
Complete package price includes binocular, removable handle, aluminum-frame case, and 16x eyepieces. If you need a mount, choose either the Oberwerk 5000 tripod/head, Manfrotto MT190X3 tripod/MVH500AH head, or the gorgeous Oberwerk TR3 hardwood tripod for the XL Series. 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.
Here is a BT-70-45 review by Phil Harrington from the July 2013 issue of Astronomy Magazine.
These premium-quality eyepieces increase the magnification of the Oberwerk BT Series binoculars. Available in 3 focal lengths (16mm, 12mm, 8mm) that give 1.5x, 2x, and 3x the magnification of the stock 23.9mm BT eyepieces. They have precision adjustable twist-up rubber eyecups, a very wide 70° AFOV, with excellent sharpness to the edge of the field. The barrels are threaded to accept 1.25? filters.
