Oberwerk 45° 80mm Binocular Telescope

Catalog description

Oberwerk 45° 80mm Binocular Telescope, part number OBER031, is a discontinued product from the 2007–2011 catalog. It was last listed at $1395.00, up from a low of $1295.00.

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 45° 80mm 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. The same fork mount and hardwood tripod (as shown) that comes standard with the BT-100-45 is available as an option or use with your own favorite mount (bottom-mount plate is tapped with standard 3/8 threading). 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.
