Product information

Description

The Celestron SkyMaster Pro ED 20x80mm Porro binoculars combine 20x magnification with 80 mm objective lenses, BaK-4 prisms and ED glass to deliver bright, high-contrast views at long distances. Designed for serious astronomy and long-range terrestrial observation, these binoculars use fully multi-coated optics with Celestron’s XLT coatings to maximize light transmission and reduce reflections. The Porro prism layout and large objective diameter support improved depth perception and strong low-light performance while a rugged rubber-armored chassis and retractable eyecups provide practical field durability and comfortable viewing for eyeglass and non-eyeglass wearers.

Advantages

ED objective lenses reduce chromatic aberration and improve edge-to-edge sharpness, producing clearer, more accurate color rendition than standard glass. BaK-4 prisms combined with fully multi-coated lens surfaces and XLT coatings increase optical throughput, yielding brighter images with better contrast in dusk, dawn, and nighttime conditions. The 80 mm objectives offer substantial light-gathering capability for faint deep-sky targets and distant terrestrial subjects, while the Porro prism design enhances three-dimensional perception. Built-in features such as retractable eyecups with more than 15 mm eye relief and a tripod-adaptable balance rail add versatility for extended observing sessions or digiscoping.

Suitable for

Astronomy: Moon, planets and bright deep-sky objects
Wildlife observation at long distances
Coastal and marine watching at dawn or dusk
Digiscoping and tripod-mounted photography
Landscape scanning and long-range terrestrial surveillance

How to use

Hold the binoculars steady and adjust the central focus wheel until the image is sharp. Use the right-eye diopter adjustment to compensate for differences between your eyes, then fine-tune the central focus for both eyes. Retract or extend the eyecups to achieve comfortable eye relief—twist the eyecups down to use the binoculars with glasses. For prolonged observation or higher stability at 20x magnification, mount the binoculars on a standard photographic tripod using the built-in adapter on the balance rail. When using filters or 1.25” astronomical eyepieces, thread them carefully into the eyepiece housings to ensure correct alignment.

Usage recommendations

For best results in low-light astronomy and long-distance observation, use a sturdy tripod or monopod to reduce shake. Clean lenses with a soft brush and lens cloth; avoid touching optical surfaces with fingers. When observing bright objects such as the Moon, consider neutral density or lunar filters to reduce glare. Store the binoculars in a dry place and use the protective case to prevent impacts; allow optics to acclimatize to outdoor temperatures before precise focusing.
