Four Stars Solar filters can be separated from binocular. 4These will be perfect for the eclipse! I purchased the 10x42 model for viewing the solar eclipse this summer. The binoculars are sturdy and well-made. The price was far less than the sun filters I was considering to attach to my regular binoculars. It is easy to find the sun while looking through them. You can see sunspots easily. The sun appears as a white circle through the binoculars. Everything else is almost completely black. The sun appeared about the size of a quarter while looking through the binoculars. I could see small clouds moving in front of the sun. The binoculars were easy to fit to the size of my face/eyes, and they were also easy to focus. I think that these will be perfect to view the eclipse! 5Great Binos and easy to use. These Binos are GREAT! They are well made and easy to use. They adjust just like regular binos. They have a focus knob in the center and a diopter adjustment on one of the eyepieces. The width also adjusts narrower or wider to fit different eye spacing. The directions describe how to adjust and use the binos. The sun filters are inside of the binoculars so they are protected from damage. They are ABSOLUTELY black when you look through them unless you are looking at the sun. To find the sun, you kind of have to scan the sky but once you find it, it resolves the solar disk nicely. My only suggestion for Celestron is to make the eye cups a bit larger. I found myself cupping my hands around the eyepieces to block the sun from sneaking into my vision. Not really a big deal but it would be nice if the eye cups had a flange around the outer diameter.Once you find the sun, it appears white with a slight yellow hue. I didn't see any sunspots but the sun may have just been quite the times I was viewing it. I can't wait to give these a spin during the 2017 eclipse!Overall, these are a VERY affordable way to view the sun up close. They are designed and built with high quality and well worth the money for curious viewers and serious observers. 5Stellar performance in a binocular Celestron EclipSmart 2017 North American Total Solar Eclipse Binocular, Black, 10x42 (71238)The Celestron EclipSmart 10x42 Solar Binoculars offer a generous 10x magnification, meet and conform to ISO requirements for filters used to safely observe the Sun, and allow for mounting on tripods or monopods with a tripod adapter (purchased separately). These are special-purpose binos for direct visual observations of the Sun for solar eclipses, sunspots, and transits. Features that the EclipSmart 10x42 Solar Binocular share with its normal binoculars cousins are interpupillary distance adjustment (distance between the centers of each eye), diopter adjustment, folding rubber eyecups, focus dial, dust covers, and strap.The EclipSmart 10x42 Solar Binocular weighs approx. 2 lbs and has an easy-to-grip rubber exterior coating. If you prefer to not hold something up to your eyes (or have trouble doing that), consider a binocular or tripod mount. These can be purchased from Celestron or other vendors, or you can build your own. To attach a tripod adapter (sold separately), unscrew the cap printed with the Celestron logo from the front of the binocular. I noted no issues with my 10x42 for alignment of the Sun's images and focus was easy.A word of caution: the Sun s visible and invisible rays can cause serious damage to the sensitive tissues of the eyes. One should never modify, tamper with, or remove the solar filters. Do familiarize yourself with the product s safety notes, care instructions, and how to use -especially regarding how to position the binocular in front of your eyes before pointing at the Sun. Solar observations are fun and Celestron provides a stellar product for those who are curious about our nearest star. 5Crisp, sharp image of our star - not just for eclipse viewer, use throughout the year! 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.Pros:- 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.Cons:- 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.[UPDATE]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.*EYE DAMAGE WARNING*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. :)*EYE DAMAGE WARNING* 5Good product I now own both the 10x42 and the 10x25, and I can reasonably compare the two. The 10x42 is definitely the bulkier. Both have the same magnification, but 10x42 has a wider viewing angle. The wider viewing angle would probably be worth it if you want to be able to see the Sun s corona in one glance versus moving the 10x25 around.A nice feature of the 10x42 are the added lens caps. I ve noticed that since the 10x25 don t have lens caps it can pick up dust, lint, and oil much more easily. You can easily wipe it off of course, but the lens cap does help a lot for the 10x42. After a few days of consecutively looking at the sun, the 10x42 view has been good. The sun is white with a completely blacked out sky. The 10x25 has the same view, albeit a little hazier. Simple wipe makes it better, but lens cleaner works for sure. This is more annoying than anything.Both the 10x42 and 10x25 are good for travelling. I would say the 10x42 is about the size of large hard cover book. The 10x42 comes with a carrying case with a small shoulder strap. The 10x25 has a string for a neck strap. If price and size isn t a factor, I would recommend the 10x42. Both are good for travelling, and can fit in my luggage bag easily since I ll be flying out to find a good spot to watch the eclipse. 5Works as Advertised - Be Prepared for a Learning Curve I purchased these binoculars so that I d have something portable to allow me to be able to move around on eclipse day. The binoculars work as advertised, and provide good magnification of the sun - enough to clearly see sun spots. I also purchased a Celestron EclipSmart Solar Telescope 50 and found that that device, while less portable and slower to setup, is a fair bit easier to use.Pros:+Solid and heavy construction.+Compact, extremely portable.+Provides magnification as advertised.+Neck string is a good length.Cons:+Very difficult to use while standing and the sun is high in the sky. You can try lying down, and that works wonderfully.+Tricky to focus, tricky to aim. Usually the only thing bright enough to see through the binoculars is the sun or the sun s reflection on something else. Unlike in normal binoculars, everything but your target is pitch black so finding the sun can be a challenge. I found that more use of the binoculars allowed me to find the sun more quickly. 4great binoculars, add soft binocular covers for best use, practice sighting before eclipse. Having played with both these Celestron 10x42s and some nicer plastic rimmed eclipse glasses Solar Eclipse Glasses - Plastic - 2 Pack - CE and ISO Certified - Safe & Durable Eye Protection - Viewer & Filter Eclipse Shades (which are well made and fit well over my prescription glasses), my opinion is that for solar viewing, I would much rather have these binoculars than eclipse glasses. Looking around at anything other than the sun with the eclipse glasses is uninteresting (for the obvious reason that they block out anything other than the sun). While watching the sun, I found light from the sides quite distracting, as others have noted, due to the small eye cups.To solve the problem of small eye cups, and stray light distracting from solar / eclipse viewing, add binocular covers, e.g.Alpine Innovations Men's Bino Bandit Binocular Cover, Stealth Shadow, One Sizeor Bino Bandit - Water-Resistant Binocular Eyeshields to Block Glare and Reduce Eye-Strain- Alpine Mountain CamoThey are much more comfortable than rubber eye cup extenders /eye shields and work much better. I tried a pair of such extenders / eye shields (these ones: AmScope EG-SM Microscope Eyepiece Eyeshields or Eye-guards) and the problem, as many others have observed, is that the extenders have an asymmetric rim which rotates with the diopter and is difficult or impossible to readjust as one focuses the right eye. The Bino Bandit Binoculars are soft and super comfortable and work really well with prescription glasses.Hand holding these 10x42s in a test run was surprisingly easy, but I also got the tripod mount:Celestron 93524 Binocular Tripod Adapter (Black)which screws easily into the hinge point. We'll see how that works out during the eclipse.I also agree with many other reviewers of these and the Lunt sunocular binoculars (Sunoculars-Red with 8x the magnification of Eclipse Glasses) that sighting the sun takes some practice, and one has to be careful not to bleach one's retinas when sighting.I think that most people will not look at the sun long enough to actually hurt their eyes while finding the sun, however even if there is no danger it means that the retinal bleach spot needs time to fade before you can get the best view of the sun. It is annoying to try to pay attention to thesun with purple spots dancing around your central vision.So the best thing to do is to spot the sun, get your azimuth right and get the frame of your body perfectly in line with the sun, bring the binoculars to an approximate elevation *without* bringing them to your eyes, and get an idea of where the sun is first. Then look down, bring the binoculars to your eyes, and sweep up through the desired elevation to find the sun. 5Inexpensive, compact and powerful binoculars for solar viewing. 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! 5Be a solar observing super hero and add this to your utility belt! 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 requirementThe 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. 4
