Oberwerk 80mm 45° Binocular Telescope

The BT-80-45 is a smaller and a lighter weight version of our revered 100mm 45° Binocular Telescope. They are the least-costly giant binoculars with 45° viewing and 1.25" focusers on the market. Of course the 80mm 45° Binocular Telescope also possesses Oberwerk's signature broadband multi-coatings on every lens, including the very large porro prisms. This high power binocular telescope includes 20x fully multi-coated wide-angle eyepieces, however, because of the industry-standard 1.25" helical focusers, your favorite telescope eyepieces can be used as well. Long f/6.5 focal ratio assures excellent color correction.
The hardwood tripod and fork mount allows smooth panning from horizon to zenith. The tripod can be upgraded to our premium jarrah hardwood tripod for $100. Either tripod can also be custom laser-engraved.
We understand that accurate collimation is critical, especially at higher magnifications. This is why every Oberwerk binocular is tested and collimated before we ship it, so that you will enjoy perfectly-merged images, even at high magnifications.
