Designed to fit snugly over the aperture of the telescope, this optical glass filter blocks 99.9% of incoming sunlight, allowing you to safely observe sunspots and solar granulation in the sun's photosphere, and in the sun's natural color. The glass elements are machine-polished and triple-coated with nickel-chromium stainless steel for a scratch-resistant surface. The filter is mounted in an aluminum cell.
See solar photo on my web site that used this filter on a TV85.
