Absolutely immaculate Celestron solar filter (in original packaging )to fit NexStar 8, 8i SCT and other compatible 8" SCT telescopes.
"This Celestron solar filter is made with Baader Astro Solar safety film, which is far superior to any existing glass, Mylar or polymer filters, leading to brighter, sharper, and higher contrast images. This filter is clear and homogenous, attains the optical performance of high-quality, plane-parallel glass filters, and is diffraction limited. The double-sided metal coatings have uniform density, providing good colour balance across the entire field, which in turn ensures razor sharp images from edge to edge. The 94162 filter causes the sun to appear in its true color of neutral white, rather than blue or orange, with the sky adjacent to the solar limb a jet black.
This filter's ND-5 rating means the film transmits 1/100,000 of visible light (or 0.001-percent), while reflecting or blocking 99.999-percent of unwanted light."
