Oberwerk 45° 100mm Astronomy Binoculars Telescope Product Info

The highly-acclaimed Oberwerk 45° 100mm Astronomy Binocular Telescope 100BT45 is now improved in two very important ways for those whose primary interest is binocular astronomy - 45° oculars and a strong and smooth fork mount, which together provide comfortable viewing from horizon to zenith. Of course the new 45° 100 mm Oberwerk Giant Binoculars also has Oberwerk 's signature broadband multi-coatings on every lens surface, including the massive porro prisms. 25x fully multi-coated wide-angle eyepieces are included, but because of the industry-standard 1.25" helical focusers, your favorite telescope eyepieces can be used as well. The rest of the astronomy binocular, including the semi-apochromatic triplet objectives, is the same proven design as found in the original Oberwerk 25/40x100mm Binoculars. Complete package price includes binocular, removable handle, aluminum case, wooden tripod with fork mount, and 25x oculars. 7x50mm correct-image finderscope (as shown) is optional. 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 collimated prior to shipping- so even at 100x, you'll enjoy perfectly merged images
