The new 20x80mm Deluxe III is our finest 80mm binocular. Giant 80mm triplet objectives have a serious amount of light grasp. The triplet objective design provides excellent performance from a compact body that’s an inch shorter than the 20×80 LW. It’s fabulous for astronomy as well as terrestrial usage, such as wildlife observation and surveillance. The 20×80 Deluxe III features waterproof construction and is nitrogen-filled to prevent internal fogging. New prism mounting system uses precision floating plates (as found on our Ultra Series), which do a better job of maintaining alignment than common prism-tilt systems.

Low-reflection broadband multi-coating is used on every air-to-glass surface, including prisms. Light loss due to reflection and scattering is minimized, providing the highest level of light transmission possible. Twist-up eyecups allow quick adjustment for those that are wearing glasses and those that are not, and the precise center focus control won’t drift. The built-in aluminum mount attaches directly to a tripod head or binocular astronomy mount, with 3/8-16 threading (1/4-20 adapter included).

All Oberwerk binoculars have rugged rubber-armored metal bodies, all-glass lenses, BAK4 prisms, and right ocular diopter adjustment. Our new-for-2017 Oberwerk Heavy-Duty aluminum case is included, which provides the ultimate in protection.
