Spectrum Telescopes Solar Film Binocular Filter

These filters are designed to fit objective lens housings with an outside diameter between 98mm and 105mm. You should measure the outer diameter of your binocular's objective lens housing—not the glass itself—to ensure it falls within this range.

These filters are primarily designed for visual solar observation. While you can technically use them for photography, the solar film is optimized for the human eye, and you may need to adjust your camera settings significantly to achieve the best results.

This set includes a pair of filters because it is intended for use on both objective lenses of your binoculars. Using them on both lenses provides a natural, binocular viewing experience and is the safest way to observe the sun.

Solar film generally provides a very sharp, high-contrast view of the sun, often revealing more detail in sunspots than some entry-level glass filters. It produces a neutral, natural-looking solar image rather than the artificial blue or orange tints sometimes seen with other materials.

Yes, these filters are specifically engineered to block harmful solar radiation, making them safe for direct solar viewing, including eclipses. Always inspect the film for any pinholes, scratches, or tears before each use; if the film is damaged, do not use the filter.
