Most people have two eyes. Humans evolved to use them together (not all animals do). People form a continuous, stereoscopic panorama movie of the world within in their minds. With your two eyes tilted upward on a clear night, there's nothing standing between you and the universe. The easiest way to your enjoyment of the night sky is to paint your brain with two channels of stronger starlight with a pair of binoculars. Even if you live in — or near — a large, light-polluted city, you may be surprised at how much astronomical detail you'll see through the right binoculars!
Our editors have looked at the spectrum of current binocular offerings. Thanks to computer-aided design and manufacturing, there have never been more high-quality choices at . Sadly, there's also a bunch of junk out there masquerading as fine stargazing instrumentation. We've selected a few that we think will work for most skywatchers.
There was a lot to consider: magnification versus mass, field of view, prism type, optical ("sharpness"), light transmission, age of the user (to match "exit pupil" size, which changes as we grow older), shock resistance, waterproofing and more.
The best binoculars for you"Small" astronomy binoculars would probably be considered "medium" for bird watching, sports observation and other terrestrial purposes. This comes about as a consequence of optics (prism type and objective size, mostly). "Large" binoculars are difficult to use for terrestrial applications and have a narrow field of view. They begin to approach telescope quality in magnification, resolution and optical characteristics.
Most of our Editors' Choicesfor stargazing binoculars here are under $300. You can pay more than 10 times that for enormous binocular telescopes used by elite enthusiasts on special mounts! You'll also pay more for ruggedized ("mil spec," or military standard) binoculars, many of which suspend their prisms on shock mounts to keep the optics in precise alignment.
Also, our Editors' Choices use Porro prism optics. binoculars usually employ "roof" prisms, which can be cast more cheaply, but whose quality can vary widely. [There's much more about Porro prisms in our Buyer's Guide.]
We think your needs are best served by reviewing in three categories.
Best Small Binoculars
Editor's Choice: Oberwerk Mariner 8x40 (Cost: $150)
Oberwerk in German means "above work." The brand does indeed perform high-level optical work, perfect for looking at objects above, as well as on the ground or water. Founder Kevin Busarow's Mariner series is not his top of the line, but it benefits greatly from engineering developed for his pricier models. The Oberwerk 8x40’s treat your eyes to an extremely wide field, at very high contrast, with razor-sharp focus; they are superb for observing the broad starscapes of the Milky Way. Just 5.5 inches (14 cm) from front to back and 6.5 inches wide (16.5 cm), the Mariners are compact and rugged enough to be your favorite "grab and go binoculars." But at 37 ounces, they may be more than a small person wants to carry for a long time.
Runner-Up: Celestron Cometron 7x50 (Cost: $30)
Yes, you read that price correctly! These Celestron lightweight, wide-field binoculars bring honest quality at a remarkably
point. The compromise comes in the optics, particularly the prism's glass type (you might see a little more chromatic aberration around the edges of the moon, and the exit pupil isn't a nice, round circle). Optimized for "almost infinitely distant" celestial objects, these Cometrons won't focus closer than about 30 feet (9.1 meters). But that's fine for most sports and other outdoor use. If you're gift-buying for multiple young astronomers – or you want an inexpensive second set for yourself – these binoculars could be your answer. Just maybe remind those young folks to be a little careful around water; Celestron claims only that the Cometrons are "water resistant," not waterproof.
Honorable Mention: Swarovski Habicht 8x30 (Cost: $1,050)
From the legendary Austrian firm of Swarovski Optik, these "bins" are perfect. Really. Very sharp. Very lightweight. Very wide field. Very versatile. And very expensive! Our editors would have picked them if we could have afforded them.
Honorable Mention: Nikon Aculon 7x50 (Cost: $110)Nikon's legendary optical quality and the large, 7mm exit pupil diameter make these appropriate as a gift for younger skywatchers.
Best Medium Binoculars
Editor's Choice: Celestron SkyMaster 8x56 (Cost: $210)
A solid, chunky-feeling set of quality prisms and lenses makes these binoculars a pleasant, 38oz. handful. A medium wide 5.8 degrees filed of view and large 7mm exit pupil brings you gently into a sweet sky of bright, though perhaps not totally brilliant, stars. Fully dressed in a rubber wetsuit, these SkyMasters are waterproof. Feel free to take them boating or birding on a moist morning. Their optical tubes were blown out with dry nitrogen at the factory, then sealed. So you can expect them not to fog up, at least not from the inside. Celestron's strap-mounting points on the Skymaster 8x56 are recessed, so they don't bother your thumbs, but that location makes them hard to fasten.
Runner-Up: Oberwerk Ultra 15x70 (Cost: $380)
The most rugged pair we evaluated, these 15x70s are optically outstanding. Seen through the Ultra's exquisitely multi-coated glass, you may find yourself falling in love with the sky all over again. Oberwerk's method of suspending their BAK4 glass Porro prisms offers greater shock-resistance than most competitors’ designs. While more costly than some comparable binoculars, they deliver superior value. Our only complaint is with their mass: At 5.5 lbs., these guys are heavy! You can hand-hold them for a short while, if you’re lying down. But they are best placed on a tripod, or on a counterweighted arm, unless you like shaky squiggles where your point-source stars are supposed to be. Like most truly big binoculars, the eyepieces focus independently; there’s no center focus wheel. These "binos" are for true astronomers.
Honorable Mention: Vixen Ascot 10x50 (Cost:$165)These quirky binoculars present you with an extremely wide field. But they are not crash-worthy – don't drop them in the dark – nor are they waterproof, and the focus knob is not
located. So care is needed if you opt for these Vixen optics.
Best Large Binoculars
Runner-Up: Orion Astronomy 20x80 (Cost: $150)
These big Orions distinguish themselves by price point; they're an excellent value. You could pay 10 times more for the comparably sized Steiners Military Observer 20x80 binoculars! Yes, the Orions are more delicate, a bit less bright and not quite as sharp. But they do offer amazingly high contrast; you'll catch significant detail in galaxies, comets and other "fuzzies." Unusually among such big rigs, the Astronomy 20x80 uses a center focus ring and one "diopter" (rather than independently focusing oculars); if you’re graduating from smaller binoculars, which commonly use that approach, this may be a comfort. These binoculars are almost lightweight enough to hold them by hand. But don't do that, at least not for long periods. And don't drop them. They will go out of alignment if handled roughly.
Honorable Mention: Barska Cosmos 25x100 (Cost: $230)They are not pretty, but you're in the dark, right? Built around a tripod-mountable truss tube, these Barskas equilibrate to temperature quickly and give you decent viewing at rational cost. They make for a cheaper version of our Editors' ChoiceCelestron SkyMasters.
Honorable Mention: Steiner Observer 20x80 (Cost: $1,500)Not at all a practical cost choice for a beginning stargazer, but you can dream, can't you? These Steiner binoculars are essentially military optics "plowshared" for peaceful celestial observing.
Why we chose NOT to review certain types
Image stabilized?Binoculars with active internal image stabilization are a growing breed. Most use battery-powered gyroscope/accelerometer-driven dynamic optical elements. We have left this type out of our evaluation because they are highly specialized and pricey ($1,250 and up). But if you are considering active stabilization, you can apply the same judgment methods detailed in our Buyer's Guide.
Comes with a camera?A few binoculars are sold with built-in cameras. That seems like a good idea. But it isn't, at least not for skywatching. Other than Earth's moon, objects in the night sky are stingy with their photons. It takes a lengthy, rock-steady time exposure to collect enough light for a respectable image. By all means, consider these binocular-camera combos for snapping Facebook shots of little Jenny on the soccer field. But stay away from them for astronomy.
Mega monster-sized?Take your new binoculars out under the night sky on clear nights, and you will fall in love with the universe. You will crave more ancient light from those distant suns. That may translate into a strong desire for bigger stereo-light buckets.
Caution: The next level up is a quantum jump of at least one financial order of magnitude. But if you have the disposable income and frequent access to dark skies, you may want to go REALLY big. Binocular telescopes in this class can feature interchangeable matching eyepieces, individually focusing oculars, more than 30x magnification and sturdy special-purpose tripods. Amateurs using these elite-level stereoscopes have discovered several prominent comets.

Skywatching Events 2015Once you have your new binoculars, it's time to take them for a spin. This year intrepid stargazers will have plenty of good opportunities to use new gear.
On March 20, for example, the sun will go through a total solar eclipse. You can check out the celestial sight using the right sun-blocking filters for binoculars, butNEVER look at the sun directly, even during a solar eclipse. It's important to find the proper filters in order to observe the rare cosmic show.
Observers can also take a look at the craggy face of the moon during a lunar eclipse on April 4. Stargazers using binoculars should be able to pick out some details not usually seen by the naked eye when looking at Earth's natural satellite.
Skywatchers should also peek out from behind the binoculars for a chance to see a series of annual meteor showers throughout the year.

California sky watchers may be able to see two celestial bodies zooming past Earth in the next few days with just a pair of binoculars.
If they're savvy.
Comet Lovejoy, which won't be back for 8,000 years, is visible in the night sky, and on Monday an asteroid as wide as five football fields will make a near-Earth flyby.
The asteroid may be more challenging to spot, but "comet Lovejoy is easy," says astronomer Edwin Krupp, director of the Griffith Observatory. Still, he adds, it's subtle. Its distinguishing characteristic is its fuzziness.
At 8 or 9 p.m. Saturday -- or any clear night through the end of this month -- pick up a pair of binoculars and scout the sky.
"You're looking fairly high," Krupp said, "about two-thirds or more of the way up from the horizon and facing roughly toward the south....
"Look straight at the Pleaides, take your binoculars and sweep almost horizontally toward the right.... With binoculars, you'll feel like you're moving past a lot of stars.... Look for a fuzzy little cottonball of light that differs from the stars in that area."
The comet's tail won't be visible, Krupp said. And although Lovejoy has a greenish glow, that will be difficult to see.
"It's not really brilliant. What's distinctive is it does look fuzzy."
The comet made its closest passage to Earth on Jan. 7, when it was 44 million miles away, according to the astronomer, but moving closer to the sun has kept it bright.

By AMANDA BARNETT
A big asteroid will fly by Earth on Monday, but NASA says don’t worry — we’ll be safe.
The asteroid is called 2004 BL86. It’ll come about 745,000 miles (1.2 million kilometers) from Earth, or about three times as far away as the moon at 11:19 a.m. ET, according to NASA.
You’re wondering, doesn’t this happen all the time? Yes and no. There are lots of asteroids that pose a threat to Earth — about 550 as of January 22. None are predicted to hit anytime soon.
But asteroid 2004 BL86 (yes, we also wish it had a catchier name) is big — about a third of a mile (a half-kilometer) in size. It will be the closest known asteroid this large to pass near Earth until 2027, that’s when an asteroid called 1999 AN10 flies by us.
“While it poses no threat to Earth for the foreseeable future, it’s a relatively close approach by a relatively large asteroid, so it provides us a unique opportunity to observe and learn more,” Don Yeomans, the recently retired manager of NASA’s Near Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California, said in a NASA press release.
This asteroid is also interesting because you might be able to see it with strong binoculars or backyard telescopes. That’s a rare opportunity for most of us.
If you don’t have binoculars or a scope, you can watch from the comfort of your computer on The Virtual Telescope Project 2.0.
The asteroid was discovered on January 30, 2004, by a telescope of the Lincoln Near-Earth Asteroid Research (LINEAR) survey in White Sands, New Mexico.
