asy-2010starproduct_logo100wThe 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.
Complete package price includes binocular, removable handle, aluminum-frame case, and 16x eyepieces. If you need a mount, choose the configuration below with Manfrotto MT190X3 tripod/MVH500AH head or Oberwerk wood tripod/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- astronomy072013-1so even at high magnifications, you’ll enjoy perfectly merged images. 3-year Limited Warranty.

    :

    I received my binocular telescope today and I wanted to thank you for the expedited shipping. The binoculars are amazing!! They look gorgeous, are very solid, plus the daytime images are clearer and sharper than I have ever seen in any binocular. I really like it and hope to use it tonight for our 2nd gathering since (at last) we are supposed to have clear skies. Again, thank you so much for your help – this is going to be a great asset for my classes and my own personal use.
