Digital camera reviews of Celestron SkyMaster Giant 15x70 Binoculars w/Tripod Adapter

Digital camera Review: a very good value
Summary: 4 Stars

This was my first binocular purchase. I bought it for astronomy. Pros: good value--it works great and was cheap. I did not have any alignment issues that some others have had. Excellent for use in looking at birds in backyard with kids. Gives excellent views of the night sky, even with the narrow field of vision. Cons: the 15x is both a pro and a con--it makes things closer but the field of view is quite narrow, and you need a very stable platform for night viewing. The included tripod attachment is not good--the plastic twists too easily and the view wobbles way too much; I am buying a metal adapter to replace it. Although I bought it for night use, I think a 10x Nikon might have been better for that use; however, for backyard fun with the kids (birdwatching etc), I do like the extra mag.

Summary of Celestron SkyMaster Giant 15x70 Binoculars w/Tripod Adapter

Celestron's SkyMaster Series of large aperture binoculars are a phenomenal value for high performance binoculars ideal for astronomical viewing or for terrestrial (land) use - especially over long distances. Each SkyMaster model features high quality BAK-4 prisms and multi-coated optics for enhanced contrast. Celestron has designed and engineered the larger SkyMaster models to meet the special demands of extended astronomical or terrestrial viewing sessions. The 15x70 version is one of the most popular models in the series. It offers serious large aperture light gathering in an affordable and reasonably lightweight configuration.

Binoculars come in a wide range of shapes and sizes these days, and an even wider range of prices. It's easy to spend less than $100 or more than $500 for what may appear to be, at least outwardly, comparable models. While they may look the same, they are probably quite different on the inside.

Recently, the binocular market has seen a flood of giant binoculars at prices that were unheard of just a few years ago. In general, giant binoculars are defined as those that magnify the view 10 times or more and have 70-mm or larger front (objective) lenses. It used to be that the least expensive giant binoculars cost in excess of $150, even $200. All that changed not long ago, when the bottom fell out of the price cellar. Now, several companies import giant binoculars that sell for half that, or less.

Celestron's 15x70 SkyMaster binoculars are one of the leaders in the low-price giant binocular arena. They certainly sound good on paper. The SkyMasters include multicoated optics and BaK-4 internal prisms, two features that promise brighter, better images, and key points to look for when judging a pair of binoculars. They also come with an adapter for attaching them to a photo tripod, which is a must to use them to their fullest, and a soft carrying case. But just because they are cheap doesn't always mean they are worth the price. Would it be better to save up for a more expensive pair?

To find the answer, I had an opportunity recently to judge the SkyMasters against a pair of Fujinon 16x70 FMT-SX binoculars , one of the finest pairs of giant binoculars sold today. Like the SkyMasters, the Fujinons feature BaK-4 prisms, but also have fully multicoated optics. As a general rule, superior coatings mean superior image sharpness and contrast. But then, that should be expected, given that the Fujinons cost many times more than the Celestrons.

While the Fujinons were clearly the better performer, the Celestron SkyMasters held up admirably. Image brightness, quality, and contrast were all remarkable considering their bargain price. Although images were a little soft across the outer 25% of the Celestron's field, the overall view was impressive nonetheless.

Some inexpensive binoculars have very sloppy focusing, causing the eyepieces to tilt and shift. Not so with the SkyMasters. I found that their center-focusing mechanism worked smoothly, with no apparently backlash or wobble. Eye relief (the distance you hold your eyes away from the eyepieces to see the full field) is stated to be 18 mm, a good distance for higher power binoculars and an important consideration if you must wear glasses when viewing. The SkyMasters are also light enough to support by hand for short periods of time, although buyers would be well advised to mount them on a sturdy photo tripod.

The bottom line is, if you are considering a pair of giant binoculars, whether for bird watching, stargazing, or another recreational use, and have a limited budget, Celestron's giant 15x70 SkyMasters represent an excellent value. --Phil Harrington, author of Star Ware and Star Watch

Pros:

  • Exceptional value for the price
  • Light enough to support by hand
  • BaK-4 prisms
  • Multicoated optics
Cons:
  • Outer 25% of the field is soft and a little blurry
  • Requires a tripod to use for extended periods
