Details

The Orion Full Aperture Solar Filter with 4.57 inch Inch Diameter (116mm internal diameter) is a high quality White light glass filter for use with larger OTA diameter 4-inch/102mm telescopes, such as the Skywatcher Evostar 102mm, 80ED and 100ED Refractors, Skywatcher 102 Skymax, Orion 102mm Maksutov-Cassegrain Telescope, Orion AstroView 100 Equatorial Refractor Telescope, Orion SkyView Pro 100 Refractor Telescope, Orion 80ED and 100ED Refractor Telescopes, Celestron NexStar 4 and Orion StarSeeker 100 Computerized GoTo Refractor Telescopes.

Spaced by internal foam mounting blocks and positioned precisely by three equally spaced retention screws, this filter allows the user to observe sunspots and other surface features in complete safety.

Blocking 99.99% of harmful Solar radiation, all Orion Solar filters consist of machine-polished glass, which is triple-coated with nickel-chromium stainless steel.

Please note: All Orion solar filters are designed for use with an adequate friction fit attachment. Thumbscrews should ONLY be used to keep filter securely in place once a friction fit has been achieved.
