Meade"s Schmidt-Newtonian optics yield pinpoint stellar images over an extremely wide field-of-view with only half the coma of standard Newtonians of the same focal ratio. Schmidt-Newtonian optics are mounted in precision-machined aluminum cells, which are then mounted in sturdy steel tubes which are baked with high-grade textured enamel paint. The optical tube assembly is closed, reducing air currents inside the tube. This prevents distortion of an otherwise sharp image. Plus, a closed tube significantly helps keep the optics clean. The Corrector Lens fully corrects for spherical aberration and provides pinpoint star images. Water white glass is used in all Schmidt-Newtonian corrector lenses to maximize light transmission. The use of water white glass results in an increase of light transmission in excess of 10%, as compared to competitive telescopes using soda lime glass. Schmidt-Newtonian corrector lenses and mirrors are individually figured to create a superior optical system which is renowned for its exquisite smoothness and performance. Premium-grade Pyrex mirrors are used in all Schmidt-Newtonian optical systems, providing exceptional thermal stability versus competing models using standard plate glass
