Celestron has designed and engineered the largest SkyMaster model to meet the special demands of extended astronomical or terrestrial viewing sessions with its massive 100mm objective lenses and powerful 25x magnification. This extra-large aperture binocular ensures high performance in all weather conditions and is ideal for astronomical viewing, or terrestrial use. Due to its size, weight, and high magnification levels, this binocular should be mounted on a standard photographic tripod for use. We’ve included an integrated tripod adapter rod that allows you to mount your SkyMaster binoculars on any sturdy ¼”-20 photographic tripod in seconds. Astronomers have praised the Celestron SkyMaster for decades for its high-quality BaK-4 prisms and multi-coated optics, which enhance contrast and bring out bright, sharp images—especially in low light conditions. The binocular features soft, comfortable rubber eyecups that block stray light. Eyeglass wearers can fold down the eyecups and view with their eyeglasses on. For maximum stability and secure optical alignment, the 100mm SkyMaster model features enhanced structural reinforcement to the main binocular body. Your purchase of the Celestron SkyMaster 25x100 binoculars includes the built-in tripod adapter, objective lens caps, a rainguard, a deluxe carrying case, a neck strap, a lens cloth, and an instruction manual. Buy with confidence from the world’s No.1 telescope brand and a leading binocular manufacturer, based in California since 1960.

  • OUR LARGEST TRIPOD-MOUNTED BINOCULAR: Giant astronomy binoculars with massive 100mm objective lenses and powerful 25x magnification. Pair them with any tripod for long-distance land-based viewing or astronomical observation.
  • WORKS WITH YOUR TRIPOD: Due to their size & weight, we recommend mounting these binoculars on a traditional photo tripod (not included). The built-in ¼”-20 adapter attaches to most tripods in seconds.
  • BRIGHT, SHARP VIEWS WITH BaK-4 PRISMS: The SkyMaster is a favorite among those who view in dim conditions near dawn and dusk or at night for astronomy. BaK-4 prisms maximize light throughput to your eye so you see brighter, more detailed images.
  • DURABLE AND WATER-RESISTANT: A rubber-armored housing protects your binoculars from damage and provides a secure gripping surface. The water-resistant exterior stands up to tough conditions and unexpected rainy weather.
  • UNBEATABLE WARRANTY & CUSTOMER SUPPORT: Buy with confidence from Celestron, a leading optics brand in California since 1960. Your purchase includes a Celestron Limited Lifetime US Warranty & US-based expert tech support.
