Description
The Celestron SkyMaster Pro ED 15x70mm Porro Binoculars are designed for serious sky watchers and nature lovers who want sharp, bright, and detailed views. Whether you enjoy observing the night sky, spotting distant wildlife, or scanning scenic landscapes, these binoculars deliver outstanding performance in every situation.
At the heart of the SkyMaster Pro ED binoculars are their large 70mm objective lenses, which collect more light than standard binoculars. This allows you to see brighter and sharper images, especially in low-light conditions such as dawn, dusk, or under a starry sky. Combined with 15x magnification, these binoculars bring distant objects up close with incredible clarity, making them a perfect choice for both astronomy and long-range terrestrial viewing.
One of the key highlights of the SkyMaster Pro ED is the use of Extra-Low Dispersion (ED) glass in the lenses. ED glass is known for reducing chromatic aberration — the color fringing that can sometimes occur around bright objects — which results in crisp, true-to-life images with excellent color accuracy. Whether you are looking at the moon’s craters or the fine feathers of a distant bird, you will enjoy a clear, sharp, and high-contrast view.
The fully multi-coated optics ensure maximum light transmission and help reduce reflections and glare. This means that you can expect high image brightness and contrast even when observing faint deep-sky objects like star clusters or nebulae. The combination of ED glass and advanced coatings makes the SkyMaster Pro ED one of the best binoculars in its class.
Celestron has designed the SkyMaster Pro ED binoculars to be as tough as they are powerful. The rugged housing is built from polycarbonate and aluminum, making them strong but lightweight for their size. The body is fully waterproof and fogproof, sealed with dry nitrogen gas to prevent internal fogging even during sudden temperature changes. This ensures reliable performance in all weather conditions, whether you are stargazing in the desert, hiking in the mountains, or observing wildlife by the sea.
The binoculars also feature rubber armor coating, which provides a secure and comfortable grip while adding an extra layer of protection against accidental bumps and drops. The twist-up eyecups and long eye relief make them comfortable to use, even for eyeglass wearers, allowing you to enjoy long observation sessions without strain.
For added stability, the SkyMaster Pro ED binoculars are tripod adaptable and come with a built-in tripod adapter, making it easy to mount them on a standard tripod for hands-free viewing. In addition, the binoculars feature an RSR (Reflex Sight Ready) rail, which allows you to attach a red-dot finder (sold separately). This makes it easier to locate and track objects in the night sky, especially for beginners.
SkyMaster Pro ED’s eyepieces are threaded to accept standard 1.25” astronomical eyepiece filters. Adding the right filter can deliver game-changing views for terrestrial and celestial observing. For terrestrial observation, filters can reduce the brightness of sand, snow, and water. For nighttime viewing, filters can cut glare, minimise eye strain, increase contrast, and even combat the effects of light pollution. Remember, the binoculars have two eyepieces, so you need a set of two filters.
Whether you are a dedicated amateur astronomer, a birdwatcher, or simply love exploring nature from afar, the Celestron SkyMaster Pro ED 15x70mm Binoculars will take your viewing experience to the next level. Durable, powerful, and packed with professional-grade features, they are ready to accompany you on every adventure — from your backyard to the darkest skies.
