Hyperion Solar Film Binocular Filter - Solar Eclipse Filter - Made in The USA (4.25" (108mm). Fits Optical Tube Diameter 3 7/8" (99mm) to 4 1/8" (105mm))

If you want to witness 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 Hyperion Solar Film, which is a thin film sheet that can be used under magnification and is suitable for any telescope, refractor, binoculars, view finders, spotting scopes, cameras, or cell phone cameras. The film is mounted into an aluminum outer cell, which is durable and lightweight, and fits most binoculars. Our solar filter is easy to use and 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. SIZING: You must measure the outside diameter of your optical tube or lens before ordering the solar filter. To measure the diameter, you can use a ruler, tape measure, or caliper. You want to measure the widest distance across the end of your optical tube or lens. Measure from the outside of the casing on one side, across the center, to the outside of the casing on the other side. Order the solar filter size that is just larger than your measurement. You are comparing your measurement with the solar filter’s inside diameter. For example: A measurement of 4" (102mm) across the end of the optical tube would require a solar filter with an inside diameter of 4.25" (114mm) because it is the size just larger than your measurement. With our Hyperion Solar Film solar filter, you can enjoy 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.
