The following options offer a range of viewing strengths. If you're buying a pair of binoculars and plan to use them for other astronomy viewing, the bigger the aperture, the better, but bigger lenses also mean heavier equipment. The first number is the magnification, the second is the aperture-the diameter of the front lens, measured in millimeters. They feature a higher magnification, but higher magnification results in a shakier image––as power increases, the equipment becomes more sensitive to its holder’s small hand movements.īinoculars are rated with two numbers. For $9.95, you’ll receive two viewers with 2x magnification capabilities and a pocket eclipse guide.īinoculars and telescopes are pricier than eclipse glasses and handheld viewers but can be worth the investment. Looking for something between basic glasses and high-tech binoculars? Check out this handheld viewer from Celestron.

And feel free to go for style: TSE17 has a $5.05 stars-and-stripes five-pack, and American Paper Optics features everything from Bill Nye glasses to astronaut-themed frames. If you want a sturdier option, try these plastic glasses from American Paper Optics. You can buy a pack of five paper glasses from Rainbow Symphony for around $12. If you’re a casual observer or part of a large group, you’ll like these glasses’ low prices and bulk packaging. Whereas sunglasses only block UV rays, eclipse glasses also cut off visible light. As Guhathakurta explains, these glasses have the added protection of a solar filter.

These solar viewers give 2x magnification and protection from the sun during the partial eclipse.Įclipse glasses look like hybrids of 3-D movie glasses and sunglasses. Whether you’re a stargazing neophyte or dedicated astronomer, this gear will help you make the most of a spectacular event.

If you purchase equipment from other outlets, double check that their merchandise meets ISO standards. The American Astronomical Society’s website includes a list of manufacturers that have certified their products meet the ISO 12312-2 standard. Opt for gear featuring ISO-approved solar filters, which are about 100,000 times darker than everyday sunglasses. Keep your equipment on hand, and put it back on when the sun starts to reappear. The only time it’s safe to look at the sun without protection is during totality. It may seem odd to don protection in the semi-darkness of a partial eclipse, but staring at the sun can cause retinal injury.
To view the solar eclipse, you’ll need proper equipment. She says observing a total eclipse is transformative: “It’s akin to the way astronauts describe their first trip to space. Madhulika Guhathakurta, the lead program scientist for NASA’s “Living With a Star” initiative, says the breadth of the path makes the eclipse accessible to everyone. Most people in the continental United States live within a one- to two-day drive of the total eclipse’s path. "Totality," the part of the total eclipse when the sun is completely covered, lasts only around two minutes. A total eclipse, in contrast, is when the moon completely blocks the sun. Those within a 70-mile wide path between Oregon and South Carolina will witness a total eclipse.Ī partial eclipse occurs when the moon blocks part of the sun from view.

This year, in contrast more than 500 million people in North America, plus parts of South America and northwestern Europe, will be able to see at least a partial eclipse. The United States hasn’t experienced a total eclipse since 1979, and that one only passed over a small swath of the Northwest. Although these eclipse watchers were not totally blinded, several incurred long-term damage. About half of the patients suffered from eye pain the others reported impaired vision. In 1999, 45 patients visited an eye clinic in Leicester, England, after viewing a solar eclipse without proper eyewear. That’s because while during an eclipse, you won’t want to tear your eyes away from the show, staring directly at the sun can lead to solar retinopathy, a condition where light floods the eye’s retina. On August 21, North America will experience the first total solar eclipse visible across the continent in nearly a century–and, while it may seem illogical, this period of semi-darkness is an important time to practice sun safety. This image of a partial eclipse in 2012 was taken by NASA's Solar Dynamics Observatory satellite.Ĭourtesy of NASA/SDO and the AIA, EVE, and HMI science teams It's tempting to stare at the sun during a solar eclipse, but if you try to do so without protection, you could damage your eyes.
