Celestron 25x100 SkyMaster Porro Prism Binoculars

View the heavens and the world around you with Celestron's SkyMaster 25x100 Binoculars. These Binoculars are the ideal choice when wanting one pair that will cover both terrestrial and celestial objects. Besides for what it can show you, the SkyMaster has a lot to offer. A large objective lens, quick and easy focusing, eyeglasses friendly and a rugged exterior, it’s no wonder the binoculars were given the name SkyMaster.


The SkyMaster series of binoculars have multi-coated optics and high index BaK-4 prisms for superb light transmission and increased contrast and resolution. Coupled with large objective lenses, BaK-4 prisms offer amazing light gathering capabilities making them ideal for stargazing and other low-light applications. With higher magnifications than standard binoculars, SkyMaster 25x100 brings celestial objects up close, providing images with outstanding detail.

Large Objective Lens

The 25x magnification porro prism binoculars have a giant 100mm objective lens offering maximum image brightness in low-light and long-range conditions with multi-coated optics for sharp and clear views. The individual eyepiece focus ensured optimal focus position every time. The SkyMaster Binoculars are suitable for terrestrial or astronomical viewing allowing you to see further than you imagined.

Comfortable to Use

The durable and armored protective rubber covering gives for ultra-firm grip and the large center focus knob makes for ultra-sharp focus across the field of view. The binoculars have an integrated tripod adapter rod for ultra-stable tripod mounting and an added viewing comfort. They can be used by everyone as they offer a long eye relief which is ideal for eyeglass wearers. The Celestron SkyMaster 25x100 Binoculars arrive with a deluxe carrying case for easy travel and safe storage.​
