The best solar binoculars fall somewhere between solar glasses and solar telescopes as far as power and functionality go — but rest assured that you can view the sun without risking any eye damage.
While solar telescopes will always offer the most crisp and detailed view of the sun — you'll also be able to see plenty with a pair of solar binoculars. The best solar binoculars also tend to be more affordable, so you don't need to overspend on something you might not be planning to use very often.
With Prime Day coming up soon, it might be tempting to simply go for the best deal you find — but it's important to do your research. Our reviewers have scoured the market, weighing up features like weight, magnification level and affordability. This isn't to mention safety — which is the most important factor in any pair you snap up.
Any pair of solar binoculars you find must meet the ISO 12312-2 international safety specification to be deemed safe enough to avoid causing permanent eye damage. Dedicated solar binoculars are always the best route, because they come with in-built solar filters, so you don't need to worry about detachable filtres falling away or being dislodged — as this can potentially lead to eye damage. If, however, you aren't especially looking for any solar viewing, you can also check out our guide to the best binoculars for all purposes, whether you're stargazing or watching wildlife.
As Prime Day approaches, stay tuned for the latest deals and discounts on solar binoculars on Amazon's annual major sale for Prime members. Last year, we spotted a handful of excellent deals on binoculars, like 50% off Celestron SkyMaster 20x80 binoculars or $200 off a pair of Canon 10x32 IS binoculars. We'll be on top of the best solar binoculars deals — so make sure to keep up to date with updates from Space.com in the run-up to Prime Day.

Best mid-range
✅ You don't want to transport your telescope: They work as a good alternative to eclipse-chasers who don't want to transport all their telescope gear.
✅ You want a pair that lasts: They're a great choice if you want a pair that you can use again and again.
❌ You won't use them again: If you only want to view an upcoming eclipse and nothing beyond that, there are more affordable options.
❌ You want a lightweight pair: They are fairly heavy and bulky, so are better used when sitting down or mounting them on a tripod.
🔎 Celestron EclipSmart 12x50: Specialist binoculars that offer a great close-up view of sunspots. However, their bulky size means they require a little patience, practice and preparation. They're a wise choice if you're after something serious that will last beyond the next eclipse. ★★★★
You should consider the Celestron EclipSmart 12x50 if you're hoping to get up close and personal with the sun anytime soon — and they offer incredible close-up views of sunspots and other details.
With a fantastic 12x magnification, you can see the sun 12x bigger than you would with the naked eye, and you'll benefit from 50mm lenses with solar filters ingrained into them from the outset. Unlike regular binoculars, you can guarantee the security of appreciating these views without risking eye damage, given the Celestron EclipSmart 12x50 binoculars meet the 12312-2:20 international safety standard.
The porro prism design is renowned for producing good contrast, clarity and less light loss compared to roof prisms, giving these the advantage over the other pairs in this guide. There was a small amount of color fringing, but it was neither unusual nor distracting.
The main thing that could be a potential 'make or break' of these solar binoculars is their size and weight. Not only does the weight make them uncomfortable to use for long periods, but the weight coupled with the higher magnification also makes them more difficult to hold them still to get a steady image. We'd recommend using them on a tripod for a better experience and avoid any frustrating wobble, or take a lawn chair with you and use them sitting down. If you want even more magnification, they also sell a 20x50 pair, but these will absolutely need to be mounted on a tripod.
In our Celestron EclipSmart 12x50mm solar binocular review, we did note that some of the other parts and accessories left a bit to be desired — the eyecups were separate and easy to lose and the neck strap is a little on the slim side.
They may require a bit of patience and practice at first, as trying to find the sun in the sky with 12x magnification is not as easy as you'd first think. Plus, the solar filters mean the sun is the only thing you can actually see when you look through them. But overall, we think they're a fantastic option for taking a look at solar spectacles, and you can also use them to view sunspots to avoid them spending their lives sitting in a drawer only to come out at special solar events.

| Attributes | Notes |
|---|---|
| Design | Heavy and bulky, best used on a tripod. |
| Performance | Some color fringing, but otherwise a great view. |
| Functionality | Tripod adapter jack included. |
Best for magnification
✅ You want a durable pair: These binoculars can withstand harsh weather conditions and environments, and they're perfect for use outdoors.
✅ You want the closest possible views: With x20 magnification, you won't get much more detailed views of the sun.
❌ You want something lighter: The weight of these binoculars might be enough to put you off given they can be uncomfortable after prolonged use.
❌ You might struggle with the magnification: If you don't need to get too close to anything you're viewing, you might want to consider an alternative.
🔎 Celestron EclipSmart 20x50: These binoculars offer a great view of the sun at maximum magnification levels. You'll need to practice getting the best view of the sun at x20, but they're a great pair and highly durable if you're also planning on using them on the go. ★★★★
The Celestron EclipSmart 20x50 is a great pair of binoculars if you're hoping to get the closest view of the sun without shelling out for a more expensive telescope. This pair is worth slightly more than the excellent Celestron EclipSmart 12x50, but it's well worth the admission fee if you're keen to prioritize stunning close-up views of sunspots or any solar views.
Made from rubber-armored aluminum housing, these binoculars are a rugged and durable pair that are perfect for taking with you as you venture outdoors. Folding eyecups also means you can use these comfortably if you're wearing glasses. Like the 12x50 pair, however, the 2 lbs (0.91 kg) weight might be a problem if you're planning on using them over longer durations, not to mention the sheer size of them — they can be rather uncomfortable if you were looking for something a little more portable and versatile. Like with the Celestron Eclipsmart 12x50 binoculars, we would recommend exploring the feasibility of getting a tripod to go along with it.
But the key selling point of this pair is the magnification level. You can see the sun 20x bigger than you would with the naked eye, not that we'd recommend that. You also get the same 50mm lenses in the aforementioned Celestron binoculars—offering a fantastic field of view so you can see the complete solar disk without panning side-to-side.
Using this pair of binoculars to catch breathtaking views of the sun also means you can do so with peace of mind. Like other options in our guide, the Celestron EclipSmart 20x50 binoculars meet the12312-2:20 international safety standard — meaning no risk of permanent eye damage.
| Attributes | Notes |
|---|---|
| Design | Heavy and bulky but built to last. |
| Performance | Offers strong views of the sun. |
| Functionality | Tripod adapter jack included. |
Best lightweight pair
✅ You don't want to spend loads: They strike a good balance between quality and affordability.
✅ You want a small and lightweight pair: They are pocket-sized and lightweight — great for taking away with you.
❌ You don't want something small and fiddly: If you have larger hands, they could be fiddly to use due to their small size.
❌ You're a seasoned skywatcher: They're noticeably lower quality than premium binoculars, and their shortcomings would likely frustrate more experienced users.
🔎 Celestron EclipSmart 10x25: For an affordable alternative to solar eclipse glasses for safely viewing the sun, look no further than this pair of compact, travel-friendly and impressive binoculars with built-in solar filters. ★★★★
The Celestron EclipSmart 10x25s are a great pair of binoculars for those who want to get great views of the sun without shelling out too much. As we said in our Celestron EclipSmart 10x25 solar binocular review, they are a lightweight pair that are comfortable to wear around your neck for lengthy periods of time without feeling the strain. They also meet the ISO 12312-2 safety standard and they block infrared (IR), ultraviolet (UV) and 99.99% of visible light. Although their design is on the more basic side, they do a great job for the price.
The magnification is slightly less, 10x rather than 12x, and the amount of light this pair lets in is half, 25mm rather than 50mm. They're roughly half as heavy, though, thanks to their smaller size and roof prism design. They're also much easier for the uninitiated or those only looking to catch a quick glimpse of the sun. All that means they're also around half as much to buy.
Anyone with bigger hands might find them a bit fiddly and cumbersome, but their compact design makes them wonderfully portable. They are designed to be travel-friendly, and their roof prism design helps keep the body slim for convenience.
When it comes to the view, it's best described as an upgrade on solar glasses rather than a premium solar viewing device. We wouldn't describe the image as spectacular, or particularly bright, but you do see a lot more than you would with solar glasses. If you simply want to track the progress of the eclipse without seeing that much detail, they're ideal.

| Attributes | Notes |
|---|---|
| Design | Small and portable roof prism design. |
| Performance | Not optically amazing. |
| Functionality | Best used for tracking the progress of a solar eclipse. |
Best all-rounder
✅ You wear glasses: They're suitable to use with glasses and sunglasses.
✅ You want something compact and lightweight: There are certainly lighter options available, but at 1.12 lbs / 508g, they're great for taking away with you.
❌ You're on a budget: There are much cheaper options available.
❌ You want high magnification: 8x magnification isn't bad, but the Celestron binos in this guide have higher magnification.
🔎 LUNT 8x32 SUNoculars: While they're pricier than the other options, these solar binoculars provide decent magnification, are lightweight and portable, easy to use and produce pleasing images of the sun. ★★★★
For a more premium pair of solar binoculars, you should consider the LUNT 8x32 SUNoculars — which offer good-quality views in a lightweight and compact package. That said, you will be expected to pay a little over the odds for them.
Thanks to their roof prism design, they're compact and lightweight — meaning they're ideal while you're on the go, while users have highlighted the hard plastic covering and eyecups for convenience. You can, for example, comfortably wear them with glasses or sunglasses. They also come with a soft case, strap, lens caps and cleaning cloth — as well as a one-year warranty.
Chief among its best features are front-mounted fully dense white light glass filters that make solar observation completely safe, because they block all UV and IR light. While you won't be able to get as close a look at the sun with its 8x magnification, you can still track the movement of the moon and make out all the sunspots you wish. The slightly lower magnification also means it won't be as hard to find the sun in the sky when you look through them. The 32mm objective lens size sits nicely in between the two Celestron pairs we mentioned above, giving a pleasing, bright image of the sun.
They come in four different colors: yellow, red, blue, and black. We think the colorful options are a smart choice to make it obvious what they are so you don't accidentally pick up your pair of regular binoculars and damage your eyesight (something you could easily do with the two Celestron pairs).
| Attributes | Notes |
|---|---|
| Design | Great build quality, and eye catching colors sets them apart from standard binoculars. |
| Performance | Produces a bright, white image of the sun. |
| Functionality | Comes with useful accessories. |
Best budget pair
✅ You want something affordable: They're great value for money and won't break the bank.
✅ You want something small and lightweight: They're perfectly pocket-sized making them great for traveling and easy for younger users to hold.
❌ You want to mount them on a tripod: They don't feature a tripod adaptor jack, so you won't be able to use them on a tripod.
❌ You want high magnification: If you want to see more details on the sun's surface and sunspots, you'll want to go for a pair with higher magnification.
🔎 LUNT 6x30 mini SUNoculars: Affordable, compact and lightweight — they're ideal for kids and adults who want to safely track the moon's movement across the sun during an eclipse. ★★★★
Look no further than the LUNT 6x30 mini SUNoculars for a pair of low-cost solar binoculars that will give you fantastic views of the sun without costing the Earth. They're an affordable pair that are built with high-quality lenses, and the front filters are made from CE-certified film, guaranteeing fantastic viewing quality. You can also benefit from zero UV and IR exposure, which would otherwise risk permanent damage to your eyes.
While you can't make out any sunspots with its 6x magnification, this pair is great if you want to track the movement of the moon as it passes the sun during the total eclipse. The eyepieces need to be focused separately, which some users find inconvenient, but for an eclipse, you only need to focus them once, so it shouldn't be too much of an issue for such an affordable pair of solar binoculars.
They're pocket-sized and incredibly portable, not to mention lightweight, which helps younger users hold them steady for longer and makes them comfortable to have around your neck for long periods. Just make sure kids and younger users have adult supervision when using them.
They don't come with any extras like eyecups or any kind of storage box or bag, but for the price, you really can't complain. They also don't have a tripod adaptor jack, which isn't totally surprising, so if you wanted a pair you could mount on a tripod, take a look at the other options on this list.
They're available in three eye-catching colors — yellow, red and blue, and there's also a regular size which is, predictably, bigger and heavier (and much more expensive) than the minis.
| Attributes | Notes |
|---|---|
| Design | Eye catching design. |
| Performance | Magnification too low to make out sunspots. |
| Functionality | Eyepieces need to be focused separately. |
Best solar binoculars FAQ
What are the best binoculars for viewing the sun?
The Celestron EclipSmart 12x50 are the best binoculars for sun viewing due to their 12x magnification and 50mm objective lenses providing bright views. Their ISO certified solar capability makes them completely safe to view the sun, too.
Can I view the solar eclipse with regular binoculars?
No, you must never look at the sun with regular binoculars. Not unless they are protected with filter adapters that conform to ISO 12312-2 international safety standards.
Are solar binoculars safe?
Provided they conform to the ISO 12312-2 international safety standard and block infrared (IR), ultraviolet (UV) and 99.99% of visible light, then yes, solar binoculars are safe to view the sun with. The in-built solar filters block 99% of the light, so when you look at the sky, the sun is the only thing you can see with them.
Should I buy solar binoculars if I already have regular binoculars?
If you already own a good pair of binoculars, you can purchase separate solar filters to attach to them instead of buying a new pair of solar binoculars. But if you plan on viewing the sun a lot, it might be best to invest in a pair of specialized solar binoculars.
Do solar binoculars work for stargazing?
As solar binoculars block 99% of visible light, they will not work for stargazing as they'll block any starlight out completely. Binoculars for stargazing need to gather as much light as possible, whereas solar binoculars need to block out as much light as possible.
