Large aperture observation binoculars with superior build quality and optical coatings than competing models in this price range, add to that the ability to add a red dot finderscope. An excellent choice for Astronomy or long distance observing, ready to fit to any standard photo tripod for maximum stability.
Massive Objective Lenses
The 80mm objective lenses have tremendous light gathering capabilities, delivering superior low light performance, even in the dimmest conditions. Choose SkyMaster Pro for use at dusk, dawn and night time astronomical viewing.
Fully Multi-Coated Optics and BaK-4 Prisms
Every air-to-glass surface is multi-coated with Celestron’s proprietary XLT coating technology. These coatings coupled with BaK-4 prisms increase light transmission through the optical path and deliver crisp, high contrast images with outstanding resolution.
Comfort
The binocular also includes both standard and winged rubber eyecups. When lighting conditions are not ideal and there is a lot of glare or light entering from the side, switch to the winged eyecups to block this light and improve the view.
Built in Tripod Adapter and RSR “Reflex Sight Ready” Rail
The built in tripod adapter of the SkyMaster Pro 20x80 not only allows the binocular to be attached to a tripod for added stability but it also acts as a balance rail by sliding along the center support rod. A red-dot finder can also be attached to the center support rod utilizing the removable rail. When properly aligned with the binocular, the red-dot finder will allow objects to be brought into view quickly.
Lightweight, Waterproof Construction
The polycarbonate and aluminum housing allows the binocular to be lighter weight without sacrificing its durability. The housing with protective rubber armor is extremely rugged and durable with the ability to handle tough use. The fully waterproof housing for use in all weather conditions provides peace of mind when unexpected weather rolls in. The housing is also filled with dry nitrogen gas to prevent the internal lenses from fogging when moving between extreme temperatures or when using the binocular in damp conditions.
Enhanced Magnification
Bring distant objects into view with 20x magnification - great for observing celestial objects in greater detail, searching for wildlife in the brush or viewing a distant object on the horizon.
