Oberwerk 100mm Binocular Telescope

Amateur astronomers have been asking for this for years, and it's finally here- a special version of the Oberwerk Astronomy Binocular with 1.25" non-rotating helical focusers! Just like the 25/40x100mm Astronomy Binocular, broadband multi-coatings (non-reflective green/purple) are used throughout, including on the massive porro prisms. Two matched pairs of fully multi-coated wide-angle eyepieces are included- 24.43mm ( 25x ) and 10mm ( 62x ). And because the helical focusers are a non-proprietary 1.25" design, your favorite 1.25" eyepieces can be used as well. The eyepieces do not rotate when focusing- a feature found only on high-end helical focusers. The rest of the binocular, including the semi-apochromatic triplet objectives, is the same proven design as found in the original 25/40x100mm, but the cast aluminum body has a beautiful automotive-quality champagne finish, giving it a more contemporary look.

Complete package price includes binocular, removable handle, lightweight nylon form-fitted case, wooden tripod with removable table-top tripod, and two pair of oculars. An optional 7x50mm correct-image finderscope (as shown at lower left) is available. Binocular is pre-tapped for the finderscope's precision-ground dovetail base (no adjustment required- just lock it in and it's aligned). Because accurate collimation is critical at higher magnifications, every Oberwerk binocular is tested and collimated prior to shipping- so even at 62x, you'll enjoy perfectly merged images.
