Best Solar Binoculars – Top Reviews in 2021

If you want equipment to view the sun, but solar telescopes and solar glasses are too much or not enough, then solar binoculars will be a perfect balance. Solar-viewing binoculars are just like standard binoculars, but when used correctly, allow you to look at the sun, magnified.

Using binoculars to stare at the sun can be such a fascinating study. It’s especially interesting during a solar eclipse. The best feature about these binoculars is that you still get adequate magnification power, which is a bit better than solar glasses but not quite as powerful as the magnification of a solar telescope.

Most models are designed to protect you from harmful rays of sun that can do damage to your eyes. Looking at the sun for even a second without protection can do irreparable damage to your eyes. The most important feature is the ISO industry safety rating so always make sure the binoculars you use have the best possible rating.

It’s also very important to note that it’s not safe to use this equipment without first making the proper adjustments. Never assume the equipment is already set and always take the time to ensure you’ve set it. Follow these instructions to set your equipment properly before viewing the sun.

Set Your Solar Binoculars Before You Use Them

Before loading your solar binoculars into your favorite solar backpack, make sure to configure it properly. Like with a solar telescope, setting your optical equipment is easy. All it requires is that you set the diopter control. To do this you’ll be using the two controls on your equipment; the center focus (in the center of the unit) and the diopter control (at the eye-placement end of the lens). You’ll also be using an objective cover. An objective cover typically comes with the equipment, but it can be purchased separately.

To set your diopter control:

  1. Place the objective cover over the the right objective lens.
  2. Looking down, turn your body toward the sun.
  3. Remain looking down and place the unit comfortably to your eyes. Note that you will not be able to see anything yet because of the solar-protective filter.
  4. Raise your gaze upward, looking through the eyepiece until you see the sun.
  5. Adjust your center control until the disc of light is in focus through the eyepiece. Leave the center control where it is and do not readjust it from focus.
  6. Lower your gaze away from the sun, looking downward through the eyepiece.
  7. Take the unit away from your eyes to switch the objective cover to the left objective lens.
  8. As before, look comfortably downward through the eyepiece.
  9. Raise your gaze again to find the sun in the lens.
  10. If the sun is now in focus, you’re done. If not, adjust your diopter control until the sun is in focus. Now you’re ready for the best view of the sun.

When you’re done looking at the sun, ALWAYS look downward to the ground before removing the equipment from your eyes. And remember to wear proper sun protection, like this solar escape hat.

Now that you’re familiar with how to safely enjoy sun-viewing, let’s take a look at some of the most popular models available online. As you read the reviews below, keep in mind how you, personally, intend to use yours. Will it be only on occasion? Will you need them to be rugged and durable? The comparison of these reviews below will help you make the right choice for investing in this unique and fascinating solar equipment. (Looking for more cool solar products?

Instead of white light filter lenses, they filter the light through CE-certified film.

What to Consider When Buying

What to Consider When Buying

You should be extra careful when buying solar binoculars. Never buy a pair of binoculars that do not come ISO (and/or CE) safety certified. Since you’ll need an objective lens cover, it’s best to look for a model that automatically comes with one. Do not attempt to use your solar binoculars without a lens cover. Here are some other important features to consider:

White light filters: some models can have either built-in filters made of glass, or CE-certified film or removable filters. Removable filters can also be made of glass or film, and they can be either custom-made for your specific binocular model or universal. The best models have built-in glass filters, which offer the highest degree of protection. However, some models with removable filters are more versatile, allowing you to make other observations too.

Magnification and lens aperture: The main reason to buy binoculars instead of eclipse glasses is magnification. You can use them to watch the eclipse, to track planetary transit, or observe sunspots. Most high-end equipment has at least 10x magnification and a wide lens aperture; usually 25mm or over. Lower magnification is also acceptable, especially if your main purpose is to watch an eclipse.

Build quality: solar viewing equipment is often employed by kids for their science projects. That’s why you should invest in a resistant instrument that can withstand harsh use. A rubber-armored aluminum body is your best bet, as these units provide better grip and also have a better impact resistance.

Accessories: It might not seem important, but accessories can enhance your user experience. Some of the most useful accessories include soft or hard carry cases, neck straps, lens covers, and a lens cloth.


A pair of these binoculars are a must-have if you want to observe solar activity throughout the year or watch an eclipse event. They’ll come in handy if you want to explore the solar system as well. The market is full of choices, from models with built-in glass filters, to more versatile alternatives with removable filters.

Which product is the best for you largely depends on your purpose and budget. If you only want to watch eclipses now and then, a cheaper option could be ideal. If you’re an astronomy enthusiast or need great gear for a science project, a pair with high-quality lenses, glass filters, and a greater magnification is undoubtedly a better choice.

Regardless of your needs or purpose, we hope this article has helped you find the right selection. Whatever your choice, all the solar binoculars featured on our list will surely offer a quality view of the sun, safely.
