Celestron SkyMaster Pro 20x80mm binoculars

This robust pair of binoculars combines strong magnification with large objective lenses to bring distant scenes and night sky details closer. The Celestron SkyMaster Pro 20x80 provides 20x magnification and 80 mm objectives for brighter images in low light, making it useful for astronomy at dusk, dawn and nocturnal wildlife observation.

Key Points

These binoculars use Porro prisms with BaK-4 glass to support sharper edge-to-edge resolution and improved contrast. The optics feature multi-coated surfaces with Celestron's XLT-style coatings, which, according to the manufacturer, increase light transmission and reduce reflections. A rubber-armoured exterior improves grip during longer viewing sessions and helps protect the instrument against bumps and knocks. The design is waterproof and nitrogen-purged to resist fogging and handle unexpected weather while outdoors.

Usage Recommendations

For handheld use, 20x magnification can be demanding, so a sturdy tripod or monopod is advisable for steady views during extended sessions. When observing the night sky, allow the eyes to adapt to darkness first; these large objective lenses will gather more light but steady support improves perceived sharpness. Clean the lenses with a soft brush and microfibre cloth to avoid scratching the coatings, and store the binoculars in the deluxe carry case after use to protect from dust and moisture.
