As an educational outreach professional I have had to prepare for the Great American Eclipse this August and I have been sourcing as many outreach tools as possible, that are lightweight and easy to use. The Celestron EclipSmart 10x25 Solar Binocular definitely address that requirement

The Binoculars are very well made with a durable metal construction and rubberized skins to keep it cool while observing the Sun even over extended periods of time. The optics are exceptionally clear and crisp. Because there is no reference point you can visually see when using the binoculars, finding the Sun is a bit of a challenge the first few times for new users but once you give them ergonomic advice it becomes second nature.

Having had eye surgery I was happy to see that these binoculars do have a center focus with a diopter adjustment on the right eye. I was able to dial in focus to get a nice sharp image and I was able to resolve medium sized or larger sunspots with ease….We just need more of them!
While the binoculars work fantastically there are some points that I was not super keen on and can probably be addressed on future models:
• Since these are for solar observing they would have been much better if they had deeper or adjustable eyecups. Many first timers find
themselves looking at their own reflection at first because of the stay light filtering in around the ends.
• The thin rope style neck strap is not easily replaceable and would be better suited to have had a better designed removable system.
• Celestron should have taken advantage of its signature Orange color and have rubberized these binoculars in Orange rather than black to help
distinguish these as solar observing binoculars. People looking at you observing may assume that you are using normal binoculars and try to
mimic these actions with their own equipment, not realizing the differences.

All that said these are a definite plus and I look forward to buying more for outreach as we get closer to August. The price makes it easily affordable and the compact size and included pouch make it portable and accessible at any time. Kudos Celestron on another top notch product.

The quality of the Celestron EclipSmart 10x42 Solar Binocular is quite exceptional. The sun focuses into a very sharp sphere and is almost rendered in natural color (just slightly bluish); the optics are excellent, which is what I expect from a Celestron product.

Although I purchased the binoculars for the 2017 solar eclipse, these binoculars are also useful before and after the solar eclipse. If you are interested in following sunspots year-round, this is the least expensive way to observe the sun.

- Excellent optics.
- The filters render a pleasing color and level of brightness. You could view the sun for a while without eye strain (although, I recommend placing a shroud over you to block out the sunlight around you).
- Smooth center focus control with right eye diopter adjustment (for people of eyes that focus differently).
- Very high-quality design, fit/finish.
- They feel very solid and thanks to the rubberized skin, easy to grip.
- Tripod adapter mount! Unscrew the cap with the Celestron logo (in front of the center focus) and purchase an inexpensive Binocular tripod adapter. With the adapter, you will be able to lock its position on the sun to allow casual observers to view the sun without the difficulty of manually looking for the sun.

- I am rather surprised that Celestron didn't label these binoculars so that they stand out as obvious solar binoculars. I imagine that people will easily assume that you are crazy for looking at the sun with regular-looking binoculars. Or worse, accidentally encourage a less knowledgeable person to mimic you with regular binoculars. :-O
- The filters are not removable... or at least, not easily removable. This isn't necessarily a 'con'. In fact, it is probably good that the binoculars have this single purpose, in order to avoid one from making a foolish and permanently damaging mistake.
- Considering their purpose, it would have been nice for Celestron to include the tripod adapter.

Overall, I am very pleased with this purchase and looking forward to using them in Wyoming, for a public viewing.

I have attached a photo that shows the EclipSmart binoculars attached to a tripod, using the Celestron 93524 Binocular Tripod Adapter Celestron 93524 Binocular Tripod Adapter (Black). This little connector is recommended to make it easier to find and lock in on the sun for extended periods of time. I am also using a Gosky Gosky Universal Cell Phone Adapter Mount - Compatible with Binocular Monocular Spotting Scope Telescope and Microscope - For iPhone Sony Samsung Moto Etc -Record the Nature of the World cell phone adapter to connect my smartphone to one of the eyepieces.

Question: Why can't I use regular binoculars to view the sun if I am wearing protective solar eclipse glasses?

More than once, I've been asked if one can use regular binoculars to look at the sun if they are wearing solar eclipse glasses. I cannot emphasize this enough... NO, NO, NO! You cannot do that! Attempting to do so will cause irreversible damage to your eyes because regular binoculars will concentrate enough sunlight to instantly burn through ANY solar eclipse glasses. If you wish to have a closer view of the sun, you must purchase specially made binoculars, designed to filter the sunlight BEFORE it enters the optics. I hope this public service warning will save, at least, one person's vision. :)

I'm gearing up for the upcoming eclipse, so I decided to add this pair of binoculars to my inventory of equipment. I'm very happy with the performance of the 10x25 pair. They provide plenty of resolution and the 10x magnification provides a much more satisfying view of the sun than a simple pair of eclipse glasses.

To get a feel for this, know that the sun takes up about a half a degree of the sky. 10 times magnification increases this to about 5°. If you hold out two fingers at arms length, the width of those fingers is about 5°.

I was also pleasantly surprised by the compact size and convenient carry case with belt loop.

While I intend to view the eclipse with these, they also allow for viewing of sunspots. There were a few small sunspots visible on the day I received these and they were clearly visible.

The only criticism I can think of is that there must be a way to manufacture a pair of these that are permanently fixed at a focus of "infinity", as there is never any need to use these for anything other than solar viewing. Looking anywhere else would be useless and provide a black image anyway, as these were designed to block out nearly all light. The thin string/strap is not even to be criticized, as the binoculars are so light that they will not be uncomfortable.

Be sure to use these safely! Point them at the ground, put your eyes to the eyepieces, and then lift your head to face the sun. Then when done viewing, tip your head down to the ground before removing the binoculars. This way you will avoid accidentally looking at the sun without the binoculars.

Happy viewing!

Solar filters can be separated from binocular.

wasn't sure what to expect. as i turns out they are brilliant. easy to use and aim at sun. i will add a WARNING though. DO NOT use them near children unless you clearly tell them ordinary binoculrs are NOT to be used to look at the sun.

These look like their basic Up close binocular fitted with internal filters, they give a blue image that show any large sunspots, they work fine though do not expect mind blowing detail, the case is basic and I replaced the simple strap, these are far better than the 10x25 version for just a bit more money

These are regular binoculars modified with the addition of solar filter material.
Everything's fine; good price and all.
Only problem is that the filter film used by Celestron makes the sun look pure white in colour; whereas most other astronomical filters make the sun look like you would expect, a yellowy-orange colour. I was disappointedin the colour but not disappointed enough to send them back.
Important note: This is the highest magnification you should get,
At 5X maginfication, any shake in your hands has a minimal effect on the image you are seeing.
But shake is magnified a lot by these binoculars which magnify at 10X, so the image that they produce is pretty bouncy.
