CelestronEclipSmart Safe Solar Eclipse Binoculars – Large & Powerful 20x50MM Solar Binoculars – Exclusive Solar Binocular – Crystal Clear Views of The Sun, Solar Eclipses, Transits & Sunspots

The 20x50 binoculars provide a very clear and nicely magnified view of the sun. You can clearly see sunspots if they are there. I was planning to mount this on a tripod but thought I would try them without it first. Using it only handheld, it can be a bit challenging to find the sun. What I found worked best was to find the visual location of the sun wearing approved solar viewing glasses, and then you have a better idea how to position yourself with the binoculars. You do need to move slowly when viewing through the binoculars because the sun will quickly move in and out of view due to the high magnification. I also found that when using it handheld, there is a fair amount of image shake even though I have pretty steady hands. Again, with the high magnification, this is not unexpected. So, all things considered, I will definitely be buying a tripod adapter mount, and I'm sure it will make the experience with these binoculars even better. Overall, I recommend these binoculars, and look forward to using them during the April 2024 eclipse.Update 10/26/23: I bought a tripod adapter (FANAUE Binocular Tripod Adapter Quick Release) and, as expected, it makes a world of difference. I now have a nice clear, shake-free, view of the sun. I found an easy way to get the binoculars aligned is to turn your back to the sun and, while looking at the shadow on the ground, adjust the binoculars to minimize the size of the shadow. It's probably harder to try to explain in words than it is to actually do, but I attached a picture that shows what it looks like when properly aligned. When doing this, I was consistently able to get the sun in the field of view on the first try. I also included a photo I took of the Sun through the binoculars with my Samsung S21 mounted on with a Tridaptor cell phone holder. The color distortion around the edges is from the camera, not the binoculars. The direct view through the binoculars is a lot better than the photo shows. Overall, I'm very happy with the binoculars.

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*

Très bonnes jumelles, image très nette et collimation parfaite. Construction solide. Bon achat!

Es al principio raro usarlos pero cumplen muy bien su función perfectos para el próximo eclipse

No conozco unos binoculares iguales. Excelente tamaño, resolución y estabilidad. La luminosidad del sol es un poco débil. Tal vez me gustarían más los 10x42

Ce sera pour l,éclipse total du 8 avril au Québec

Love these. Bought them for upcoming eclipse, but great for looking at sun anytime.Partial phases of the eclipse are really enhanced with close up view. See sunspots etc.Note that these are only good for looking at the full sun or during the partial phases of an eclipse.May be difficult for some to use. They appear totally black when you look through them until you find the sun. Only reason not a 5 rating is because of the foregoing. It is difficult adjust eye width or focus when sun not in field of view. My advice is to adjust to your eye width as best you can and make sure the focus wheel is turned completely anti-clockwise. Adjust once you find the sun disk.
