The Vixen ULF-90 fits most 80-90mm aperture telescopes and some larger camera lenses and spotting scopes. For a 90mm aperture, it fits over outside diameters of 90-109mm. For the smaller outside diameters, tabs should be folded inward to grip lens. Its spring-folded fins hold onto lens better than metal or plastic rings. This lens filter is 100% safe for direct solar viewing or photographing.
Solar lens to use for binoculars, cameras, spotting scopes, and small telescopes
