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. Celestrons 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 EDs lens surfaces are fully multi-coated and feature Celestrons proprietary XLT optical coating technology. These powerful coatings similar to the ones youll find on our observatory-grade telescopes decrease reflectivity for higher optical throughput across a broad range of the visible light spectrum. Whats 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. Objective Lenses The 70mm 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 viewingespecially at dawn or dusk.

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 users eye behind the eyepieces at the correct distance for optimal viewing.
