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.
