Filtre solare ULF50-2 Binocular

Universal Solar Filters (ULF) are cardboard filter kits for safe solar observation. They are based on the SolarLite Filter by Thousand Oaks. After assembly, the filters can be attached to the lens. They then attenuate the sunlight so far that a safe view of the photosphere with its sunspots is possible.

ULF-50: Fits most camera lenses which either are attached permanently to a camera or which came included with a DSLR bundle. 50mm aperture, fits over outside diameters of 50-69mm. For smaller outside diameters, tabs should be folded inward to grip lens.
