The Celestron SkyMaster Pro 20x80 Astronomy Binoculars will take you by surprise.
Observe the night sky on-the-go with the Celestron SkyMaster Pro 20x80 Astronomy Binoculars.
With a huge 80mm aperture and 20x magnification, the Celestron SkyMaster Pro 20x80 offers close-up views of the Moon, star clusters and constellations, making it the 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 Pro 20x80 Binoculars are great for longer-distance views of terrestrial objects at land or sea. The large aperture of these binoculars make them great for use in low-light conditions, whether you're pointing up at the night sky or using them during dawn & dusk.
With fully multi-coated optics built on the well-renowned porro prism, BaK4 optical design, the SkyMaster Pro 20x80 offers high-quality views with enhanced contrast. Despite their large size, the design of the binoculars also make them fairly comfortable to hold, especially since the chassis is protected by a rubber armour with an ultra-firm grip.
The SkyMaster Pro 20x80 Binoculars are incredibly versatile with tripod-adaptability and an included carry case.
What takes the SkyMaster Pro a step beyond the regular SkyMaster?
Celestron's SkyMaster Pro Astronomy Binoculars Range is a step above the regular SkyMaster model. Designed for serious astronomers on-the-move, the SkyMaster Pro offers significant advantages over its more affordable counterpart.
- Improved Optics: The SkyMaster Pro offers significantly clearer views than the regular SkyMaster. For starters, the Pro variant features Fully Multi-Coated Optics, with all air-to-glass surfaces fully multi-coated with Celestron XLT Lens Coatings. With these coatings, expect even brighter, crisper and clearer views of the night sky.
- Improved Chassis: The SkyMaster Pro features a lightweight polycarbonate / aluminium housing. This means that the Pro variants retain a similar weight to the standard models with added protection, resulting in a robust, fully waterproof chassis. The Pro variants are also nitrogen-purged, making them fog-resistant in damp conditions or during switches in temperature extremes.
- Red Dot Finder Compatible: One of the hardest parts of using a pair of high-power binoculars is how difficult it can be to find things in the night sky. The SkyMaster Pro features a revolutionary Reflex Sight Ready (RSR) Rail, allowing a Red Dot Finderscope to easily be attached / detached when needed. A Red Dot Finder helps find objects quickly, whether you're pointing up at the night sky or using your Pro binoculars during the day.

Q1. What makes Celestron SkyMaster Pro binoculars different from standard SkyMaster models?
SkyMaster Pro binoculars feature upgraded optics, including fully multi-coated lenses with Celestron’s XLT coatings, improved mechanical construction, and a rugged polycarbonate/aluminium body for better performance and durability.
Q2. Are the SkyMaster Pro binoculars good for astronomy?
Yes, they are designed specifically for astronomy. With large objective lenses (70mm or 80mm depending on the model), they gather ample light for clear views of the Moon, planets, star clusters, and bright deep-sky objects.
Q3. Can I use SkyMaster Pro binoculars during the day?
Yes. While optimised for night sky viewing, their high-quality optics and long-range capabilities make them excellent for terrestrial viewing, such as wildlife, landscapes, and distant objects.
Q4. Do I need a tripod to use them?
Due to their size and high magnification (e.g. 15x or 20x), using a tripod is strongly recommended for stable, shake-free viewing.
Q5. Can I attach a red dot finderscope?
Yes. SkyMaster Pro models include a detachable RSR rail, allowing you to mount a red dot finderscope to assist with locating celestial objects more easily.
Q6. Are these binoculars waterproof?
Yes. SkyMaster Pro binoculars are waterproof and nitrogen-purged, making them resistant to internal fogging and suitable for outdoor use in varying weather conditions.
Q7. How should I clean the lenses?
Use a soft blower to remove dust, then gently clean with a microfibre cloth and optical lens cleaner. Avoid touching the lenses with fingers or using rough materials that can scratch the coatings. We recommend the saxon Optical Lens Cleaning Kit.
Q8. What’s the best way to store them?
Store the binoculars in their included carry case in a cool, dry place. Keep the lens caps on when not in use and avoid exposing them to extreme heat or humidity.
