Oberwerk 80mm 45° Binocular Telescope

The BT-80-45 is a smaller and lighter version of our highy-acclaimed 100mm 45° Binocular Telescope. It is the least-expensive binocular on the market that offers 45° viewing and 1.25" focusers. Of course the 80mm 45° Binocular Telescope also has Oberwerk's signature broadband multi-coatings on every lens surface, including the massive porro prisms. 20x 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. Long f/6.5 focal ratio assures excellent color correction.
The fork mount and hardwood tripod allows smooth panning from horizon to zenith. The tripod can be upgraded to our premium jarrah hardwood tripod for $100.
Because accurate collimation is critical at higher magnifications, every Oberwerk binocular is collimated prior to shipping- so even at high magnifications, you'll enjoy perfectly-merged images.
