Alpine Astronomical 80mm Baader AstroSolar White-Light Solar Filter for Binoculars

Unlike many white-light solar filters that produce views of the sun with a red-orange, bluish, or yellow tint, the Alpine Astronomical 80mm Baader AstroSolar White-Light Solar Filter reveals the sun in its natural white color to show more surface details with greater clarity. The filter is mounted onto a clear-white IR-rejecting plastic ring, which acts as stabilizing element for the filter cell, and the ring is in turn mounted onto the aluminum front frame. The thermal expansion coefficient of the plastic and the film are similar to minimize thermal stress on the film for increased resistance to developing pinholes or tears. With the ability to be installed on the outside or inside of a binocular optical tube or camera lens, this filter provides a safe way to view the sun or to capture images with a camera. To fit most binocular configurations, one side of the filter housing is cut off and should be installed on the inside of the optical tube to prevent the housings from interfering with each other when t...
