  • Description

    The Celestron SkyMaster 15x70 Astronomy Binoculars offer state-of-the-art technology and phenomenal performance. Despite their "SkyMaster" name, these astronomy binoculars are nearly as exceptional for long-distance terrestrial use. SkyMaster binoculars bring star fields, Jupiter and its moons, Saturn's rings, and globular star clusters into clear view, allowing for a spectacular and unique peek at the universe.

    Explore the Cosmos

    The SkyMaster 15x70 features high-quality BAK-4 prisms and multi-coated optics for enhanced contrast and maximum light allowance. Additionally, Celestron has designed and engineered the larger SkyMaster models to meet the special demands of extended astronomical or terrestrial viewing sessions. In dark-sky environments, even such objects as galaxies and nebulae are within reach of a Celestron SkyMaster Binocular. For added utility and convenience, the Celestron SkyMaster 15x70 binocular is water-resistant and tripod-adaptable with the included tripod adapter.

    Included Tripod Adapter

    The Celestron 15x70 SkyMaster binoculars include a tripod adapter for fixing the binocular to any standard photo tripod.  To install tripod adapter simply un-thread the logo cap in front of the focus knob on the front of the binocular.  This will reveal a female thread to install the tripod adapter.  Then simply connect the binocular to your tripod for ultra stable viewing.  

    Ideal for stargazing.... but also excellent for daytime use

    The 15x70 SkyMaster is excellent for night time stargazing and lunar viewing but also shine for long-distant terrestrial applications.  Point the binocular at scenic mountain ranges or view ships out on the water for amazing views at 15x magnification.

    About Celestron

    In the late 1950s, Tom Johnson, founder of Valor Electronics, built a telescope from scratch to introduce his sons to the wonders of stargazing. What began as a hobby soon grew to be Johnson’s driving passion, and in 1960, he formed an Astro-Optical Division within his company. That department eventually became Celestron.

    Prior to Celestron, skilled opticians painstakingly produced high-quality Schmidt-Cassegrain telescopes one by one, hand-figuring the glass for hours. Johnson wanted to bring observatory-grade optics to the masses, but achieving his dream required streamlining the manufacturing process. Johnson’s solution was developing ultra-precise match plates, allowing for mass production of the Schmidt corrector. With this groundbreaking new technique, Johnson created Schmidt-Cassegrain telescopes of unparalleled quality, and brought them to market at a surprisingly low price. Celestron telescopes were an instant smash success that catapulted the hobby of astronomy to new heights.

    In 1970, Johnson unveiled his landmark product: the Celestron 8, with its standout orange tube, high-end optics, and $1,000 price tag. Armed with the “C8,” thousands of amateur astronomers observed celestial objects previously seen only in professional observatories. The C8 cemented Celestron as an industry game-changer and the world’s premier telescope brand.

    For more than 50 years, Celestron has continued to lead the market, creating dozens of revolutionary new products including telescopes, sport optics, and microscopes. With more than 80 employees around the world, Celestron remains guided by our founding principles as we commit to ever-increasing global growth. Today, we still produce our flagship product—the 14-inch EdgeHD optical tube—at our headquarters in Torrance, California, using Tom Johnson’s signature method.

Customer Q&A

1 - 5 of 12

  • Q1: Do these have diopter adjustment?

    A: You can adjust the right eye diopter, as well as the center focus knob.

  • Q2: Does the SkyMaster 15X70 include a photo tripod adapter so I can use it with my current tripod?

    A: Yes, they have a built-in rigid photo tripod adapter.

  • Q3: Will objects (stars, nebula, etc.) appear brighter with the 15x70s than through a standard 10x50, or does the higher magnification affect the apparent brightness?

    A: Higher magnification affects brightness, but since the 15x70 SkyMaster's 70mm objective lens has nearly double the area of the 10x50s' 50mm lens, the darkening effect of the greater magnification is erased. The 15x70 Skymasters will be brighter than 10x50s.

  • Q4: Will the image be erect or inverted?

    A: The SkyMaster's images are right side up.

  • Q5: How do these compare in physical size to a "standard" pair of porro prism 10x50s?

    A: They are quite a bit larger. The chambers are longer and wider. This one is recommended to be used with a tripod.

  • Q6: How much does the Skymaster 15x70 weigh? I am 85 so wonder if I can hold it or will need a tripod. If so what kind? Will it provide better distance vision than a 10x50 wide angle binocular?

    A: The Celestron SkyMaster 15x70 binocular weighs 4 pounds, and that's a real load for hand held viewing. We'd suggest a tripod, particularly because of the 15X magnification. The Optavian Field Tripod should do the job nicely. The SkyMaster will make distant objects appear 15 times as close as they actually are. However, the high magnification level decreases the field of view, so you'll only be able to see an area 230 feet wide at 1,000 yards' distance. That makes following any kind of motion somewhat difficult. On the other hand, 10x50 Wide-Angle binoculars will make objects appear only 10 times as close but will give a 341-foot field of view. This makes following wildlife or sports action much easier. In addition, the 10x50s weigh only 1.95 pounds, making them much easier to hold than the SkyMasters, hence easier to use without a tripod. In our opinion, then, 10x50s are a better choice for general-purpose viewing. The 15x70s are a good choice, though, for stargazing or viewing distant objects over, say, the ocean.

  • Q7: I just ordered the 15x70 skymaster . do they come with any lens covers or do i need to buy the seperatley and do you recomend any

    A: The Celestron SkyMaster binoculars come with lens covers.

  • Q8: I live on the lake and have 7-15x35 binoculars. They are not powerful enough and can see only a small area. I do not want to spend a lot of money. What do you recommend?

    A: If 15X binoculars aren't powerful enough and the field of view is too small, the answer is to increase objective lens size, along with magnification. Zhumell's 20x80 Super Giant Binoculars offer plenty of power and a reasonably large field of view. They've been getting terrific customer reviews.

  • Q9: If I buy it will it come with a strap and a carry case or do I need to get those things separately?

    A: The Celestron 15x70 does include a strap and a carrying case.

  • Q10: Is the 15x70 Skymasters fogproof & Nitrogen-filled?

    A: Unfortunately, no, the Celestron 15x70 SkyMaster binocular is not fog-proof and nitrogen-filled.

  • Q11: The Skymaster 15x70 binoculars are are said to be fully coated. Do you mean fully multi-coated, that is coating of all air to glass surfaces and is the coating magnesium fluoride?

    A: The Skymasters are fully "multi-coated" and it is a magnesium fluoride coating they use.

  • Q12: What are the dimensions of the SkyMaster 15x70 Center Focus Celestron binoculars?

    A: The dimensions of the Celestron Skymaster 15x70 are 7.9" x 9.3" x 3.6".
