SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

These worked well for the solar eclipse.

I would probably get a solar telescope or lens next time.

On the afternoon of the solar eclipse (8/21/17) I was able to view the partial eclipse from Brooklyn NY. Although the place was not on the path of totality, it was still a beautiful sight, thanks to the solar binoculars.

Great product.

Perfect solar binoculars

These are amazing. Used them for the solar eclipse, and although it was initially a little hard to get them dialed in for my vision, eye distance etc, once they were set up they stayed that way and I watched pretty much the whole eclipse through these biniculars - barely used my paper glasses at all!

They were okay, but filters over our own bins worked better

Didn't use these much because the view just wasn't as good as our combo of filters plus our better binoculars. The eye pieces were a little small and the folding of the binocular were a little fiddly - as is common for small compact binoculars like these.

Great all-time solar viewing tool IF handled carefully...

This is a wonderful tool for solar viewing. We ordered four, one for each of us, for the 2017 eclipse. Using these magnified the sun ten times, to where the sunspots were easily visible. These are so much better than the glasses and made watching the eclipse more enjoyable. There seems to be some quality control problems though. Two of the four were perfect. One was distinctly lighter than the other three which caused a concern (there are three darkening filters inside each tube -- makes one wonder if one is missing in one). One arrived optically unaligned. With no time for exchange due to the nearness of the eclipse, we unscrewed the viewing lenses on the unaligned one to discover that the inside elements were at two different depths in the tube. It explained the problem. These are slid in and held in place by friction. This binocular arrived separately so its package may have been dropped in shipment. By lightly tapping the binocular against a padded hard surface, we were able to move both lenses forward. Then we cut a piece of soft lens cloth to cover the top of a nickel to push each lens back into the tube at the same depth. We added a nickel at a time until it focused mid-point in the binocular's center adjustment. We then reset the filters and screwed on the lens cap and it worked perfectly. We never unscrewed the cover for the less darkened binocular because we read that they are nitrogen filled. It works fine but it makes one wonder if it is working on two darkened filters rather than three. The cost is very reasonable and it made watching the eclipse more enjoyable. In the end we never used our glasses, only these.

Glad I bought these

I really enjoyed these for the eclipse. It was nice having something more than the cardboard glasses. These kept the correct color of the sun rather than making it orange. Easy to use. Good quality feel.

To small and a hassle to view the eclipse! Didnt use them

The eye cups were to small and a hassle to view the eclipse! Didn't even use them to view the eclipse!

Two questions on the 10x25 bino: 1) What is the diameter of the eyepiece? 2) Is there an eye cup that rolls down for people who wear glasses?
Asked by: Paul
The eyepiece's virtual aperture (exit pupil) is 2.5mm (.09"). The eyecups roll down for those who wear glasses.

question

Just out of curiosity from an amateur... It seems strange to have a diameter of 25mm or 42mm and then block 99.999% of the light. Wouldn't it make sense to have something more like a pinhole camera (but with a tiny actual lens)? I already ordered this pair, but just wondering about this question.
Asked by: Chris Brewster
Thanks for your question Chris. Aperture still does play a part in viewing with a solar filter. The larger aperture will still allow for a better view.
