This Founder BOS spotting scope has a large 72 mm aperture for bright views during the day and nice light-gathering at night. The ED (extra-low dispersion) lens is made from Ohara FPL-53 glass, resulting in sharp images with virtually zero distortion and very low chromatic aberration. When not in use, you'll like the elegant attached lens cap as well as the included hard carry case!

Quality Interchangeable Eyepieces: The BOS72 comes with two 12.5 mm long eye relief (20 mm) 1.25" eyepieces. The lenses are fully multi-coated and install easily into the binoviewer with twist lock collars.

Diopter Focus: Don't have 20/20 vision? Simply turn the Diopter Focusing Ring, with its + and - markings, until the image is sharp.
360 Rotation: The green collar that connects the binoviewer to the spotting scope can be loosened, allowing you to rotate the eyepieces for the most comfortable viewing. This is especially nice when doing astronomy and the scope is pointing up near the zenith!
Serialized Product: A name plate on the back of each spotting scope is stamped with a serial number. This allows for better quality control at the manufacturer level and better. more targeted service should you require it.
Cool Vixen-type Dovetail: You can attach your Bino-One to either a tripod (via a 1/4-20 threaded hole) or to an alt-azimuth or equatorial mount via the included Vixen-Style Dovetail plate.
Strong Carry Case Included: Each spotting scope comes in its own hard carry case for the ultimate in protection for storage or travel. Custom cut foam snuggles your scope with binoviewer and eyepieces attached, and there is room for more eyepieces should you desire.
