I cut two 52mm circles out of the one sheet and inserted them into 3d-printed rings for my binoculars. They made the Eclipse-viewing much more satisfying for me and my family.

I used these to make filters for my binoculars for the April 8 2024 eclipse. Overall they worked OK (glad I had them), but not great. I knocked off one star because they were a little darker than I expected, and one star because they are so fragile. The fragility I could have prepared for, but the listing has so little info I was not aware until they were scratched enough to affect image quality. You might consider this user error, but considering that probably most people are like me using this for a specific event that you don't get a second chance at, I feel like this really should be stated clearly up front and I would have been OK with it.Regarding darkness, with my 10x42 binoculars, it looked good but noticeably (but not enough to matter much) darker than looking at the sun through solar glasses without magnification. With my 7x35's, it was quite a bit darker, making it not much easier to see more detail than through solar glasses without magnification. It may be that these are intended for higher quality devices but these are what I use for birding without issues.Regarding scratching, I cut out circles of this material and glued them into 4 frames I 3d printed to fit on 2 pairs of binoculars. Once they were complete, I put them in a small box to protect them, but in the box they could move around a tiny bit. Shortly before C1, I put them on my binoculars and left them on until totality. I was pretty careful with my binoculars like I usually am, but I would do things like put them in my lap or on a table on top of some clothes where the could run against clothes. Around the time totally ended, they were so scratched that the image quality was reduced to the point that I could no longer see any more details with binoculars than without. Over all, I got some good views of the eclipse before totality with them, and they weren't very useful after totality due to the scratches.

We bought these in preparation for the great solar eclipse. Granted, that's not something that happens every day, but we were very pleased that we could see sun spots with our telescope. When I told our homeschooling co-op about it, they thought it was cool and now we are planning on an activity where I bring it and all of the kids can see the sun in a telescope. It worked perfectly and was safe. It was a bit of a process to customize it for our telescope, but was definitely worth it. Plus we looked, and it was a lot cheaper to go this route than to buy a dedicated telescope for sun viewing. This was a great value!

As an avid stargazer and amateur astronomer, I recently purchased the solar filter sheet to enhance my solar eclipse viewing experience, and I must say, it has truly impressed me.First and foremost, safety is paramount when observing the sun, and this solar filter sheet delivers on that front. Its high-quality material effectively blocks harmful UV rays, infrared radiation, and intense visible light, ensuring my eyes and equipment are protected during solar observation sessions. I appreciate the peace of mind knowing that I can safely explore the sun's surface features without risking damage to my lens and camera.Lastly, the orange tune color really stands out compared with whiteish color using ND filter. A true color experience.

Full disclosure: First solar eclipse photo op for me! I have multiple total, and partial, lunar eclipses in my experience base but no solar chops! Until now. The Thousand Oaks Optical brand solar filter is quite economical, if you're on a tight budget, or just frugal by nature. And there's also the argument against buying an optical glass, dedicated size, filter for one lens or telescope aperture! The T.O.O. filter is metallized Mylar film, not glass! You can buy the size for the largest lens or telescope you own and then adapt it to smaller lens sizes as needed, with a bit of additional fabrication. I adapted the 4" X 4" filter to fit the sunshade of a 70-300mm zoom lens, which I could fit on, or remove as needed. I fabricated a filter mount from white card stock and Scotch Magic Tape. As such, the fit was secure enough to not need any additional support. If it was really windy, a few pieces of Magic Tape would have secured it to the sunshade!I made some test exposures well before the event started and dialed in a starting exposure and captured the image in pic 1. Sunspots are visible in the center and left of center. Cloud cover interrupted the rest of the event, and pics 2 and 3 are marred by wispy clouds moving across the frame. As my location was several hundred miles east of totality, the eclipse was a partial for me. I was happy to have caught what I did and gained some experience from it too. The filter performed exactly as presented! Please note: The filter can be used, as delivered, by simply folding and taping the corners to whatever optical device you plan to use. However, there's a risk of leaving a gap through which sunlight can pass, causing damage to the eye or optical gear! There are a number of sites online dedicated to amateur telescope making that have information on fabricating and adapting all sorts of gadgets and accessories for astronomy Do it right, you only have one pair of eyes. Safe viewing and clear skies!! Hope this helps

Ho acquistato questo filtro in vista dell'eclissi di sole prevista l'anno prossimo. Ho fatto qualche prova con la mia macchina fotografica (una bridge con lunghezza focale da 400 mm) e sono soddisfatto del risultato. Il filtro funziona bene e protegge perfettamente. Il pacco è arrivato in tempo e il contenuto all'interno è ben protetto.

Folie ist top, erziehlt sehr gute Ergebnisse an einer DSLR mit Teleobjektiv. Die Sonne erscheint in einem angenehmen Orange, und auf den Fotos sind auch Sonnenflecken gut zu erkennen. Die Folie ist gut zuschneidbar, allerdings auch sehr dünn und wirkt dadurch etwas fragil. In Filterhaltern wie der Cokin Z Serie lässt sie sich leider nicht verwenden, zum anbringen an ein Objektiv muss man etwas kreativ sein.Ich möchte an dieser Stelle auch den Kundenservice von shy_h loben, da meine erste Sendung auf dem Postweg von Israel nach Deutschland verloren ging. Es wurde umgehend und unkompliziert ein Ersatzprodukt mit schnellerem Versand und Trackingnummer losgeschickt.
