Description

If you want to enjoy the beauty and power of the sun, whether through photography or direct observation, you need a solar filter that can protect your eyes and your equipment from the sun’s intense light and radiation. That’s why we offer you our premium solar filter, which is specially designed for binoculars. Our solar filter is rated ND5, which means that it blocks 99.999% of the sunlight, making it safe for viewing the sun’s surface and features, such as sunspots and eclipses. Our solar filter is made of Helios Solar Glass, which is a high-quality glass that has a reflective coating on both sides to enhance the contrast and clarity of the sun’s image. The glass is mounted into an aluminum outer cell, which is durable and lightweight. Our solar filter is easy to use and fits most binoculars. It has a slip-on design that allows you to slide it over the sky end of your binoculars securely. The filter is secured and centered to the binoculars with nylon thumb screw(s) and felt tabs, which prevent any damage or scratches to your binoculars. With our premium solar filter, you can experience the sun’s beauty and power without any risk or hassle.

**Determining Correct Solar Filter Size** The solar filter should slip over the sky end of your optical tube. Measure the outside diameter of your optical tube using a ruler, tape measure, or caliper. Measure from the outside of the casing on one side, across the center, to the outside casing on the other side. Order a solar filter with an inside diameter slightly larger than your measurement. For example, if your measurement across the end of your optical tube is 4 inches (102mm), choose a solar filter with an inside diameter of 4.25 inches (114mm)—just larger than your measurement.

I don't have any way to test the quality of these filters. I just checked them for leaks and pinholes as instructed and then put them up to my eyes (on binoculars). In retrospect, that was a lot of trust. Fortunately, it worked out fine. I've used them on a few normal days and one solar eclipse day, and I'm happy to report zero eye problems. If they didn't work pretty well, I'm sure the light of the sun concentrated by my 8x42 binos would have done some serious damage in a fraction of a second. So I'd say they do what they promise.
