Celestron Skymaster Pro ED 20x80 Binocular (USA Set)
Celestron Skymaster Pro ED 20x80 Binocular
Celestron SkyMaster Pro ED binoculars are the ideal choice for amateur astronomers or anyone who observes at great distances. The SkyMaster Pro ED uses superior optics, coatings, internal parts, and housing materials. With large objective lenses, BaK-4 prisms, ED glass, and fully multi-coated optics utilizing Celestron’s proprietary XLT coating technology, the view through a SkyMaster Pro ED sets the standard for astronomy binoculars.
ED Objective Lenses
Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual phenomenon common in magnified optical systems. SkyMaster Pro ED delivers edge-to-edge sharpness with excellent color correction and razor-sharp images.
Not all ED glass is created equal. Celestron’s high-quality ED glass delivers brighter, sharper images than non-ED binoculars. The difference is especially apparent in low-light conditions.
Coatings and Prisms
All of Celestron SkyMaster Pro ED’s lens surfaces are fully multi-coated and feature Celestron’s proprietary XLT optical coating technology. These powerful coatings, similar to the ones you’ll find on our observatory-grade telescopes, decrease reflectivity for higher optical throughput across a broad range of the visible light spectrum. What’s more, the prisms inside the binocular are made of high-quality BaK-4 glass, further boosting light transmission. Working together, the fully multi-coated lenses and BaK-4 prisms deliver more light from your target to your eye for brighter, more detailed views.
The 80mm objective lenses offer plenty of light-gathering ability for superior low-light performance. The objective diameter-to-magnification ratio is ideal for scanning the skies, observing the Moon and planets, and exploring all the best deep-sky objects. Celestron SkyMaster Pro ED also makes an excellent choice for long-distance land-based viewing—especially at dawn or dusk
Custom-designed rubber armor and a durable chassis protect your SkyMaster Pro ED binocular from damage without weighing you down. Viewing through SkyMaster Pro ED binoculars is comfortable for eyeglass and non-eyeglass wearers alike, thanks to the retractable eyecups and more than 15mm of eye relief. Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses by twisting the eyecups down. For those who do not wear eyeglasses, the eyecups position the user’s eye behind the eyepieces at the correct distance for optimal viewing
