Vixen Optics teamed a powerful binocular with a solid ash wood Berlebach tripod to create their ARK 20x80 Astronomical Binocular rig. Ideal for astronomical and terrestrial viewing, the powerful optic boasts BAK4 Porro prisms which offers a rich depth of field, with an ultra-wide 70° apparent angle of view to provide users with an immersive observational experience. Anti-reflection multi-coated optics limits light loss to boost image brightness, while integrated pull-out lens shades helps to prevent peripheral light from interfering with primary light transmission, further ensuring bright and clear images. Complementing the optical performance are nitrogen-filled optical tubes to prevent internal fogging when moving from one temperature extreme to another.

A center bar on the binocular helps to stabilize the optic's large objectives, and an integrated 1/4"-20 tripod adapter provides a solid mounting point for the included head. The adapter can slide along the bar and lock into place for precise balancing, so the head can pan and tilt fluidly without over-straining it. The head is capable of tilting 90° forward and back, so it's ideal for both astronomical and terrestrial viewing, especially if the binocular is set on a balcony and you're looking down at a boat or bird.

The included tripod is produced by Berlebach in Germany and made of solid ash wood, with a matching tray that not only keeps small accessories safe but locks the legs at a 23° pitch for optimal stabilization and vibration reduction. This adjustable-height tripod not only offers a rock-steady observational base for a wide range of users; it also presents a refined and elegant look.
