DayStar Filters

Utilizing an ingenious spring-folded assembly design to hold them securely in place, these 90mm White-Light Universal Lens Solar Filters (2-pack) from Daystar Filters allow you to safely view or photograph the sun and solar eclipses. They are safe for solar viewing with binoculars spotting scopes, or multiple optics and lenses without having to move the filter. Made from 12312-2 ISO-certified SOLARITE film, each filter blocks more than 99.999% of intense light, plus 100% of harmful IR and UV radiation to reveal sunspots and super granules on the solar surface. Made to fit on the front of camera lenses, telescopes, spotting scopes, binoculars, or other optics and imaging devices, they accommodate housings, sunshades, and dew shields with an outside diameter from 85-99mm (3.34-3.89"). The filter has a clear aperture of 90mm, so vignetting may occur when used on lenses and optics that approach the maximum recommended diameter in the size range.
