Size: 15-35x70


Style: SkyMaster 15x - 35x70 Zoom


Features

  • POWERFUL 15-35X ZOOM BINOCULAR: Giant binoculars with massive 70mm objective lenses and powerful adjustable zoom for 15 to 35x magnification. Pair with any tripod for long-distance land-based viewing or astronomy.
  • WORKS WITH YOUR TRIPOD: Due to their size & weight, most users mount SkyMaster binoculars on a traditional photo tripod (not included). The included 14-20 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.

Description

Celestron has designed and engineered the larger SkyMaster models to meet the unique demands of extended astronomical or terrestrial viewing sessions. This special zoom version packs even more power, with adjustable magnification that goes from 15x to a maximum of 35x power. Due to its size and weight—including its very large objective lenses—this binocular should be mounted on a standard photographic tripod for extended periods of use. We’ve included a tripod adapter rod that allows you to mount your SkyMaster binoculars on any sturdy ¼”-20 photographic tripod in seconds. These extra-large & powerful binoculars ensure high performance in all weather conditions and are ideal for astronomical viewing or terrestrial (land-based) viewing over long distances. 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 binoculars feature soft, comfortable rubber eyecups that block stray light. Eyeglass wearers can fold down the eyecups and view with their eyeglasses on. Your purchase of the Celestron SkyMaster 15-35x70 binoculars includes the 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.

  • Good for the price
Size: 15-35x70 Style: SkyMaster 15x - 35x70 Zoom
I wanted a good set for concerts and festivals and was pleasantly surprised to learn you can use it for telescope setup. They are HEAVY, so if you do plan on going to a concert, plan for a different way to carry them or your neck will get tired. They are over a foot long. I didn't do much testing with it, but had a really clear, up-close view from about 150yards. No issues with glasses or otherwise. They do come with caps to all the lenses and a carry bag, along with a mount for a tripod. They aren't Zeiss, but I don't need that level of quality for what my purposes are. ... show more

  • Total Surprise -These ZOOM binoculars Actually Work!
Size: 15-35x70 Style: SkyMaster 15x - 35x70 Zoom
The quality of these ZOOM binoculars surprised me for I have found that ZOOM binoculars do not work well. With this pair however, Celestron has restricted wisely the ZOOM to 35X the maximum usable with the giggle inherent in hand- held binocular viewing. At the same time, with the ZOOM bar on maximum with this unit, they provide good image quality and eye relief. I have NEVER seen this! For the purposes of use for night astronomy or casual day use the user WILL NOT BE DISAPPOINTED! Also the Included Tripod Mount (metal) and neck strap are of good quality which is unusual at this price point. ... show more

  • Wow! You won’t be disappointed!
Size: 15-35x70 Style: SkyMaster 15x - 35x70 Zoom
Birthday gift for my son. We were using regular binoculars 7x35. These binoculars literally put the moon in our face! We can see the moons of Jupiter clear enough to count them! AND one night we saw the rings on Saturn! Highly recommend these binoculars for amateurs wanting to up grade for a better night sky viewing experience. I also recommend a stand to mount them on. More stability, less jiggling. Clarity is good too! Use the strap around your neck for safety. They are on the heavier side as well. You won’t be disappointed with these binoculars! ... show more

This is a good pair of binoculars. You need a tripod for them because they are heavy.

Muy buenos, es necesario usar un buen trípode ya que son bastante pesados y no se puede usarlos por mucho solo con las manos, están dedicados a observación astronómica no tanto para paisajismo
