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 enhance 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 reasonable prices. 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 quality ("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. Compact 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.
- Small, highly portable binoculars can be hand-held for viewing ease.
- Medium binoculars offer higher powers of magnification, but still can be hand-held, if firmly braced.
- Large binoculars have bigger "objective" lenses but must be mounted on a tripod or counterweighted arm for stability.
Best Small Binoculars
Editor's Choice: Oberwerk Mariner 8x40 (Cost: $150)
Runner-Up: Celestron Cometron 7x50 (Cost: $30)
Honorable Mention: Swarovski Habicht 8x30 (Cost: $1,050)
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)
Runner-Up: Oberwerk Ultra 15x70 (Cost: $380)
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 conveniently 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' Choice Celestron 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.
Enjoy your universe
If you are new to lens-assisted stargazing, you'll find excellent enhanced views among the binocular choices above.

May the photons be with you. Always.
Skywatching Events 2015
Once 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, but NEVER 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.
Excerpt from People
by Nicole Weisensee Egan
Brittany Maynard, who became the public face of the controversial right-to-die movement over the last few weeks, ended her own life Saturday at her home in Portland, Oregon. She was 29. "Goodbye to all my dear friends and family that I love. Today is the day I have chosen to pass away with dignity in the face of my terminal illness, this terrible brain cancer that has taken so much from me … but would have taken so much more," she wrote on Facebook. "The world is a beautiful place, travel has been my greatest teacher, my close friends and folks are the greatest givers. I even have a ring of support around my bed as I type … Goodbye world. Spread good energy. Pay it forward!"
Doctors told Maynard she had six months to live last spring after she was diagnosed with a likely stage 4 glioblastoma. She made headlines around the world when she announced she intended to die – under Oregon's Death with Dignity Act – by taking a fatal dose of barbiturates, prescribed to her by a doctor, when her suffering became too great.
On Oct. 6, she launched an online video campaign with Compassion & Choices, an end-of-life choice advocacy organization, to fight for expanding death-with-dignity laws nationwide.
"For people to argue against this choice for sick people really seems evil to me," she told PEOPLE. "They try to mix it up with suicide and that's really unfair, because there's not a single part of me that wants to die. But I am dying."

A Heartbreaking Choice
Arriving at her decision was a gradual one, she said."It's not a decision you make one day and you snap your fingers," she told PEOPLE.
"Really, from the beginning, all the doctors said when you have a glioma you're going to die," she told PEOPLE. "You can just Google it. People don't survive this disease. Not yet."
After researching her options, she decided not to try chemotherapy or radiation.
"They didn't seem to make sense for me," she said, because of "the level of side effects I would suffer and it wouldn't save my life. I've been told pretty much no matter what, I'm going to die – and treatments would extend my life but affect the quality pretty negatively."
In June, she moved to Oregon with her husband, Dan Diaz, 43, her mother, Debbie Ziegler, 56 , and her stepfather, Gary Holmes, 72, so she could have access to the state's Death with Dignity Act, which allows physicians to prescribe life-ending medication to certain terminally ill patients.
"I still smile and laugh with my family and friends enough that it doesn't seem like the right time now," she said in the video recorded Oct. 13 and 14, "but it will come because I feel myself getting sicker; it's happening each week."

Her Final Months
Maynard spent the last months of her life making the most of the time she had left. She traveled to Alaska, British Columbia and Yellowstone National Park with her loved ones and explored more local attractions like Olympic National Park in Washington.On Oct. 21, she and her family took a helicopter ride to the Grand Canyon, a place she'd been longing to see before she died.
"It was breathtakingly beautiful," she said in a statement.
The following morning, though, she had her "worst seizure" so far, she said: "The seizure was a harsh reminder that my symptoms continue to worsen as the tumor runs its course."
Maynard said she was deeply touched by the "outpouring of support" she got after going public with her diagnosis and her decision.
"I want to thank people for that, for the words of kindness, for the time they've taken in personal ways," she told PEOPLE.
"And then beyond that, to encourage people to make a difference," she said. "If they can relate to my story, if they agree with this issue on a philosophical level, to get out there and do what we need to do to make a change in this country."

Maynard also talked to PEOPLE about her legacy.
"For me what matters most is the way I'm remembered by my family and my husband as a good woman who did my best to be a good wife and a good daughter," she said.
"Beyond that, getting involved with this campaign, I hope to be making a difference here," she said. "If I'm leaving a legacy, it's to change this health-care policy or be a part of this change of this health-care policy so it becomes available to all Americans. That would be an enormous contribution to make, even if I'm just a piece of it."
Before she died, Maynard asked her husband and her mother if they would carry on the work she started to get death with dignity passed in every state.
"I want to work on the cause," Ziegler told PEOPLE last month. "I have so much admiration for people who are terminally ill and just fight and fight. They are so dignified and brave. This is a different choice, but it is also brave and dignified."
She also shared with them her hopes and dreams for their future. Upstairs in the home she shares with her family are neatly wrapped Christmas and birthday gifts for her loved ones for the next year.
"She made it clear she wants me to live a good life," Ziegler says.
In her second video, Maynard, who is an only child, said she hoped her mother does not "break down" or "suffer from any kind of depression."
And for Diaz, "I hope he moves on and becomes a father," she said. "There's no part of me that wants him to live out the rest of his life just missing his wife."

Gregg Prescott, M.S., In5D GuestWhat if EVERYONE was wealthy beyond their wildest dreams and how would that affect our perceived “freedom”?I often use an analogy of freedom as a man walking his dog.

Thomas Razzeto, GrahamHancock.comMy most passionate plea is for you to wake up to your true self as pure awareness. We have all heard it said that you are not a human being having a spiritual experience, but instead, you are a spiritual being having a human experience. Yet you are not a being of any kind, spiritual or physical. You are pure awareness! And most importantly, your awareness is the One Awareness – the Divine Awareness – and as such, it is the only reality tha [...]
Nikkie Gray, Collective-EvolutionThe theory that we plan our lives was something I had never heard of before 2011. Up until that point, I could not have even imagined such a thing. Even after hearing about it 3 years ago, it took me quite a long time to let this concept into my paradigm. How I stumbled upon it wasn’t even through my avid research of the afterlife and reincarnation. It came to me through a vision I had. Before the vision, I believed in reincarnation. The idea of it ha [...]
