Daystar Filters assembled this 70mm ULF Camera Lens Filter Kit with 5 Solar Glasses to give you everything you need to view and photograph the sun safely and easily. All components in the kit are made of the 12312-2 ISO-certified SOLARITE film, which stops more than 99.999% of intense light, plus 100% of harmful IR and UV radiation—revealing large sunspots and super granules on the solar surface. The kit includes five solar viewing glasses, and one 70mm Universal Lens Filter (ULF). The lens filter can accommodate housings, sunshades, and dew shields with an outside diameter from 65-89mm. The filter has a clear aperture of 70mm, so vignetting may occur when used on lenses and optics that approach the maximum recommended diameter in the size range.
