Observe the night sky on-the-go with the Celestron SkyMaster 25x70 Astronomy Binoculars.
With a huge 70mm aperture and an unbelievable 25x magnification, the Celestron SkyMaster 25x70 offers close-up views of the Moon, star clusters and constellations, making it a great companion for nights away from your telescope. But just because they're designed for astronomy doesn't mean you can't use them during the day too! The SkyMaster 25x70 Binoculars are great for longer-distance views of terrestrial objects at land or sea. The large aperture of these binoculars makes them ideal for low-light conditions, whether you're pointing up at the night sky or using them during dawn & dusk.
With a 25x magnification, the SkyMaster 25x70 ranks among the most powerful binoculars available today.
Like the other models in the Celestron Sky Master series, with multi-coated optics built on the well-renowned porro prism, BaK4 optical design, the SkyMaster 25x70 offers high-quality views with enhanced contrast. Despite their size, the binoculars remain fairly comfortable to hold thanks to their ergonomic design and ultra-firm rubber armour grip.
The SkyMaster 25x70 Binoculars are incredibly versatile with tripod-adaptability and an included carry case.

Q1. What are Celestron SkyMaster binoculars best used for?
SkyMaster binoculars are designed for astronomy and long-distance terrestrial viewing. They’re ideal for observing the Moon, planets, star clusters, and distant landscapes or wildlife.
Q2. What’s the difference between SkyMaster and SkyMaster Pro?
SkyMaster Pro models feature enhanced optics with Celestron XLT coatings, improved internal components, a sturdier chassis, and often include a detachable RSR rail for attaching a red dot finderscope. Standard SkyMaster models offer excellent performance at a more affordable price.
Q3. Do I need a tripod to use SkyMaster binoculars?
For models like the 15x70 or 20x80, a tripod is recommended due to their weight and high magnification. Most SkyMaster binoculars are tripod-adaptable and include a tripod adapter.
Q4. Can I use SkyMaster binoculars during the day?
Yes. While optimised for stargazing, SkyMaster binoculars also perform well in daylight for viewing distant landscapes, boats, or wildlife.
Q5. Are they suitable for beginners in astronomy?
Absolutely. SkyMaster binoculars are a great entry point for astronomy, offering wide fields of view and ease of use without the setup complexity of a telescope.
Q6. Are SkyMaster binoculars waterproof?
Standard SkyMaster models are not waterproof, while SkyMaster Pro models are typically waterproof and nitrogen-purged, offering better protection against moisture and fogging.
Q7. How should I store them?
Keep your binoculars in a cool, dry place using the included carry case. Always store them with the lens caps on and avoid extreme temperatures or humidity.
Q8. Can I use a smartphone adapter with SkyMaster binoculars?
Yes, you can attach a smartphone adapter for basic astrophotography or to capture distant daytime scenes. Ensure the adapter fits the eyepiece size properly. We recommend the Celestron NeXYZ Smartphone Adapter.
