Warning: Viewing the Sun without proper protection can cause permanent eye damage, blindness, and equipment damage. As this product meets the standards of ISO 12312-2 specifications, though certification status is not available for such items (removable filters for optics and telescopes), it is safe for solar observation through its intended optics equipment. Always use approved ISO 12312-2 certified safety glasses when viewing the Sun directly. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.
