Bei der Bestellung sollte man darauf achten, daß man für den Preis nur ein kleines Stück Folie etwa die Größe DIN A 6 erhält, das höchstens für eine Teleskopöffnung von 150 mm was bringt.

This worked very well. I was able to DIY a filter for my camera lens for the 2024 total solar eclipse. I even had enough left over to DIY filters for three iPhones.

Put this on the front of my telescope and looked at the sun a couple of times. Saw the sunspots clearly and have not gone blind. Works as advertised.

I got this filter to use attached to my telescope to capture the eclipse. After making a DIY holder for the telescope and trying it out, I realized that the telescope was too zoomed in to capture the corona at full eclipse. I was able to instead use it with my Camera instead - attached to the lens and I couldn't be happier. I was able to capture all phases of the eclipse.I am still using it with the telescope for solar viewing during the day and was able to capture the sunspot that cause the Aurora to be visible further south than usual. Great buy and works perfectly.

Did not get a chance to use it as intended. Wanted it for the solar eclipse, but it arrived way too late. Came the day after the eclipse, but that aside, the material is uniform and came very well packaged. No wrinkles and I can use it in my filter frame for multiple lenses. I recommend, but plan on a slow delivery.

This filter sheet works very well. I cut a disk from it and fitted it inside a 58mm UV filter and attached it to my EF 70-300 lens. Even handheld I got decent shots of the sun including the current sunspots. This will be great for the April 8'th eclipse, unless it is snowing, raining, etc.

The best time for a person to directly view solar flares and coronal discharges from the surface of the sun is during a solar eclipse where the daytime Moon covers the body of the Sun, a very happy coincidence, allowing the activity of the Sun extending past the outside of its body to be more easily seen. But if you want to see solar flares you are going to need some magnification compared to just ordinary Sun safety eclipse glasses. That's where this large 6 by 6 inch (15.24 centimeters) sheet comes in.You would normally think that since you are collecting more light then concentrating it to a smaller area you might be subject to damaging concentrations. And the answer is yes, you will be much safer to capture any activity on film-stills or video.According to Wikipedia, "X-rays and extreme ultraviolet radiation emitted by solar flares are absorbed by the daylight side of Earth's atmosphere and do not reach the Earth's surface. Therefore, solar flares pose no direct danger to humans on Earth." and "...the duration of a flare ranges from approximately tens of seconds to several hours with a median duration of approximately 6 and 11 minutes..." depending on which wavelengths are measured.According to the National Oceanic and Atmospheric Administration, We are now in Solar Cycle 25 with peak sunspot activity expected in 2025. While we are not predicting a particularly active Solar Cycle 25, violent eruptions from the Sun can occur at any time. For the latest space weather forecast, visit NOAA’s Space Weather Prediction Center, the nation’s authority for space weather alerts, watches, warnings, and advisories. Suggest you either video or take periodic still photos of the entire eclipse process over its approximately to two and 1/2 hour time from start of partiality to end of partiality or for the length of the total eclipse which will probably be about 4 minutes in your area of the United States.In Conclusion: highly recommend this product to let you do that safely.

This was probably a once in a lifetime opportunity to catch a full solar eclipse and this stuff worked just fine. I bought a couple blanks and made custom filters for both my SLR camera and telescope.

I purchased this for the October 14, 2023 annular solar eclipse. At the time, I was planning on cutting the filter into a circle to fit on my polarized filter for me lens. When I received the filter, I realized that I would only have one shot at cutting the filter correctly as my lens filter is 95mm and the filter was not big enough for a second try. And I didn't have the time to order a new filter if I screwed up. As I was gathering the courage to grab my razer blade, my dogs wanted a treat, and I decided on peanut butter crackers. As soon as I opened my pantry door, the box holding the crackers pretty much slapped me in the face as an easy way to create a filter. And it worked very, very well. Thanks to this great solar filter sheet and my dogs, I got some great photos of the eclipse!

This was priced lower than other filters, but I am always on a budget, so I kept my fingers crossed. I didn't have to worry. The product arrived in a sturdy envelope to protect it from getting bent, and the optical quality is very good. You may find slightly better quality filters, but at a much higher price.I made this film into a screw-on filter for my DSLR, and the attached photo is of the annular solar eclipse of October 14, 2023 at the maximum from my location. Filter can of course be used for any solar photography; sunspots are easily visible in photographs, which is cool.I can recommend this product!
