Orion 4.10" ID Solar Filter for StarMax 90, Apex 90, Meade ETX-90 Detail

• A must-have for safe observation of the sun without damaging your eyes - optical glass filter fits snugly over your telescope's aperture to block 99.9% of incoming sunlight
• Fits Orion Obeserver 70mm, ShortTube 80mm, StarSeeker 80mm, and AstroView 90mm refractors; Apex and StarMax 90mm Mak-Cass telescopes; and other models (see chart below)
• Each Orion telescope solar filter is mounted in a foam-lined aluminum cell featuring three equidistant securing thumbscrews, 4x 1/16" thick adhesive foam tabs, and 4x 1/8" thick adhesive foam tabs for customized friction fit to your telescope
• Filter inside diameter is 4.10" - fits optical tubes with an outer diameter of 3.85" to 4.10" with included shim materials and securing thumbscrews
• 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

Designed to fit snugly over the aperture of your telescope, these optical glass filters block 99.999% of incoming sunlight, allowing you to safely observe sunspots and solar granulation in the Sun's photosphere. The Sun appears in a natural, whitish color. The glass elements are machine-polished and triple-coated with nickel-chromium stainless steel for a scratch-resistant surface. Each filter has three nylon thumbscrews to ensure a snug fit to the front of your telescope or binocular. The thumbscrews complement the press-fit foam lining inside the filter's durable aluminum cell to accommodate diameters up to ¼" smaller than the nominal size. A tight press fit is still required for safe solar viewing. Lifetime limited warranty.
