Oberwerk Corp. from Dayton, Ohio, introduced the BT-70-45 in the fall of 2012 as a lighter, downsized version of its flagship BT-100-45. While far less expensive than the larger binoculars, this kid brother shares many of its sibling’s finer qualities.
It should be no secret that I love big binoculars. Viewing the universe with both eyes is a more personal experience than squinting through a telescope. So, when I was given a chance to review Oberwerk’s 45° 70mm Binocular Telescope (BT-70-45), I jumped at the opportunity.
