Celestron SkyMaster Giant 15x70 Binoculars with Tripod Adapter

Celestron SkyMaster Giant 15x70 Binoculars with Tripod Adapter Lowest new price: $60.02
Lowest used price: $53.99
List price: $119.95
Brand: Celestron
Model: 71009

Celestron and ;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

Celestron NexStar 8 SE Telescope

Celestron NexStar 8 SE Telescope Lowest new price: Too low to display
Lowest used price: $750.00
List price: $1,199.00
Brand: Celestron
Model: 11069

8 inches of light-gathering aperture doesn't get more portable than this!   An 8 inch telescope is the right amount of aperture for viewing just about anything in the night sky. The Celestron NexStar 8 SE Telescope sets up and breaks down quickly (check out the video) and is great for taking to dark sky locations.   The largest of the NexStar SE family with 78% more light gathering than a 6-inch model, the Celestron NexStar 8 SE Telescope will enable you to see deep into the universe. The distinctive patented fork arm with ergonomically designed integrated hand control cradle gives solid support to Celestron’s classic 8-inch optics. The Celestron NexStar 8 SE Telescope features Schmidt-Cassegrain 8-inch aperture optics with Celestron's premium StarBright XLT coatings and a powerful 2,032mm focal length and f/10 focal ratio. The Celestron NexStar 8 SE Telescope has all the same features as Celestron’s most advanced computerized GoTo telescopes, including the revolutionary SkyAlign™ alignment technology, a sky tour feature, a database of over 40,000 celestial objects and easy to use hand control. The universe may be full of mysteries, but using the NexStar 8 SE isn’t one of them.   Whether you are a seasoned astronomer looking for a portable scope with advanced features, or just starting your astronomy adventure and looking for an easy way to enjoy the night sky, a Celestron NexStar SE telescope will help you take a closer look.   Every Celestron NexStar SE telescope includes a version of The Sky software Level 1 Planetarium Software for exploring the Universe on your PC and printing out custom star charts of the sky. In addition, you receive the Celestron NexRemote software that allows you to operate your telescope via your PC.

Amazon.com Review Celestron's Nexstar 8 SE telescope combines excellent optics and computerized "GoTo" tracking in a package that's light, portable and affordable. The legendary performance of Celestron's orange tube C8 telescope has been updated with high performance Starbright XLT coatings, and the single arm Nexstar mount now includes Celestron's easy to use "SkyAlign" technology.

The Nexstar 8 SE upholds Celestron's reputation for quality optics. When I use an 11mm Plossl eyepiece (almost 200x magnification) for example, I can easily see the Cassini Division in Saturn's rings. When I look at Jupiter, the pale orange color of Jupiter's famous Great Red Spot is visible, and I've even been able to identify the polar caps and spot dust storms on the planet Mars. A 20mm Plossl eyepiece (about 100x magnification) is a good choice for viewing galaxies and star clusters. When I look at globular cluster M13 in the constellation Hercules the high contrast XLT optics show me a glowing snowflake made of hundreds of tiny pin-point stars! And a low power 32mm Plossl eyepiece is a good choice for views of larger deep space highlights like the Andromeda Galaxy and the Orion Nebula.

Celestron's patented "SkyAlign" system makes the Nexstar 8 SE very easy to use. I just pick the nearest town from the built-in list, enter the date and time, and point the telescope at three bright stars. I don't need a star chart because "SkyAlign" identifies the stars for me. When I just want a quick look at the moon or a planet, I like to use the "Solar System Align" option. After entering the date and time, I just point the telescope at the moon and press the "Align" key. That's all it takes, the computer takes over and the telescope begins tracking quietly and accurately. At star parties I often have my Nexstar up and running while older computerized telescopes are still waiting for their alignment stars to appear in the twilight.

The Nexstar 8 SE comes with a simple red-dot finder scope and a basic 25mm eyepiece. You'll want to add a few good eyepieces to take full advantage of the Nexstar 8 SE's excellent optics. At the very least get Celestron's bargain priced Accessory Kit which includes high and low power plossl eyepieces, or treat yourself to some top rated Tele Vue eyepieces. At twenty-four pounds total weight, the Nexstar 8 SE is unusually light and portable for an eight-inch telescope. The drawback of course is that some people will find it too light. Like other Schmidt Cassegrain (SCT) telescopes there are plenty of optional accessories to upgrade this telescope with, such as heavy duty tripods and an optical finder scope. If you want to try astro-photography, however, check out Celestron's CPC 800 Telescope which features a heavy duty mount and tripod and an 8x50 optical finder scope right out of the box. --Jeff Phillips

Celestron NexStar 130 SLT Computerized Telescope Lowest new price: $389.95
Lowest used price: $299.00
List price: $769.95
Brand: Celestron
Model: 31145

Celestron NexStar 130 SLT Series Newtonian Reflector Telescope - 31145

Amazon.com Celestron’s computerized NexStar 130 SLT adds affordable "Go-To" technology to a compact Newtonian reflector telescope. By using mirrors instead of lenses, the Newtonian optics of the NexStar 130 SLT produce an image nearly five times brighter than the NexStar 60 SLT refractor telescope. The package includes everything except the batteries, and features easy no-tool setup, two good eyepieces, and even includes a student version of "The Sky" planetarium software.

The Newtonian design of the NexStar 130 SLT is optimized to produce bright images over a wide field of view. When I use an optional 32mm Plossl eyepiece, the famous Double Cluster in Perseus looks like a display of celestial fireworks with streamers of stars trailing across the 2 degree field of view. The standard equipment 25mm eyepiece magnifies the image about 26 times, with a wide field of view just right for viewing deep space objects like star clusters or the Orion Nebula.
Celestron NexStar 130
The included 9mm eyepiece (72x magnification) offers great views of the Lunar disk and globular star clusters like M13. And when I add a 2x Barlow lens to the 9mm eyepiece for a total magnification of 144x, I can easily see cloud bands on the planet Jupiter and pick up detail in Saturn’s rings.

The NexStar 130 SLT also features Celestron’s patented SkyAlign technology. With SkyAlign I don't need a star chart or a compass to align the telescope, I just enter the date and time then point the telescope at three bright stars. SkyAlign tells me the star names, and allows the telescope to find over 4,000 stars, planets, and galaxies by just pushing a button. The accurate tracking makes it easy to get high power views of the planets, and allowed me to take some great pictures using a Celestron NexImage webcam. I also like the "Two-Star align" and "Solar System align" modes because I can often get the NexStar system up and running while older scopes are still waiting for their alignment stars to appear in he twilight.

Reflector telescopes offer more light gathering power per dollar than any other design, but that value is balanced by the fact that the mirrors may need to be aligned or "collimated" occasionally. Using Celestron’s Collimation Eyepiece
Celestron NexStar 130
I had no trouble fine tuning the optical alignment, and I was rewarded with sharp views of Lunar craters even when I pushed the magnification up to the theoretical limit of 300x. The other drawback of a computerized telescope, of course, is battery consumption. An optional PowerTank battery is a handy way to power the NexStar 130 SLT, and I like to keep the tripod legs short and observe while seated because this gives me a solid and comfortable view. --Jeff Phillips
