Sharp, Handheld Stargazing
The Celestron SkyMaster Pro ED 15x70 Porro Prism Binoculars are the perfect optics for stargazing on the go. With 15x magnification and 70mm lenses, they allow you to comfortably view constellations and the surface of the Moon.
What sets these binoculars apart are the extra-low dispersion (ED) lenses, which eliminate chromatic aberration, delivering crystal-clear, sharp images with improved contrast. Combined with BaK-4 Porro prisms and fully multi-coated optics with Celestron’s XLT coating technology, these binoculars deliver impressive brightness and clarity, even in low-light conditions.
Designed for serious stargazers, these binoculars are also built to last. The durable, rubber-armoured body protects the internal optics, while the robust chassis keeps alignment intact during extended use. The 15.7mm eye relief provides a comfortable viewing experience for both eyeglass and non-eyeglass users, and the large 4.4mm exit pupil makes night-time viewing easier on the eyes.
Perfect for handheld use or mounted on a tripod for added stability, the SkyMaster Pro ED 15x70 binoculars are tripod adaptable and feature a wide 4.4° field of view, making them suitable for scanning the sky or following moving objects. With water-resistant construction and a Celestron Limited Lifetime Warranty, these binoculars are made to perform in the field or backyard observatory.

Q1. What are the main advantages of Celestron SkyMaster ED binoculars?
SkyMaster ED binoculars feature extra-low dispersion (ED) glass, which reduces chromatic aberration and delivers sharper, higher-contrast images. They are ideal for astronomy and long-distance terrestrial viewing.
Q2. Can I use SkyMaster ED binoculars for both day and night?
Yes. While designed with astronomy in mind, the high light-gathering power and sharp optics make them suitable for daytime use, such as birdwatching or landscape observation.
Q3. Can they be used without a tripod?
They can be handheld for short sessions, but due to their size and weight (approx. 2kg), a tripod is strongly recommended for longer viewing sessions to reduce hand fatigue and image shake.
Q4. Are they suitable for eyeglass wearers?
Yes. SkyMaster ED binoculars offer generous eye relief (15.7mm) and twist-up eyecups for a comfortable viewing experience with or without glasses.
Q5. How do I clean the lenses properly?
Use a soft blower to remove loose dust, followed by a lens cleaning cloth or microfibre cloth with lens cleaner. Avoid household cleaners or rough materials that may scratch the lens. We recommend the saxon Optical Lens Cleaning Kit.
Q6. How should I store the binoculars?
Keep them in a dry, cool place in their case when not in use. Use the included caps to protect the lenses, and avoid exposing them to extreme temperatures or humidity.
Q7. How do the SkyMaster Pro ED binoculars compare to regular SkyMaster models?
SkyMaster Pro ED models include ED glass and enhanced coatings (XLT), providing superior image clarity and contrast over standard SkyMaster models.
Q8. Are these binoculars good for beginners in astronomy?
Yes. They are an excellent entry point into astronomy, offering wide views of the sky without the complexity of telescopes.
