Meade LXD75 SC-8AT (f/10) Telescope Feature
- Standard Features
- Telescope Mounting: LXD75, German-type
- Setting Circle Diameters, RA and Dec.: 2.25"
- Polar Illuminated Viewfinder: included
- RA Control System: 9-speed, microprocessor-controlled, 12v DC, 72mm (2.83") wormgear
Aperture: 8-Inch. Focal Length: 2000mm. Focal Ratio: f/10. Ultra High Transmission Coatings (UHTC). Optical Tube Construction Schmidt-Newtonian and Schmidt-Cassegrain optics are mounted in precision-machined aluminum cells and mounted in sturdy steel tubes which are baked with highgrade 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. Corrector Lens Fully corrects for spherical aberration and provides pinpoint star images. Water white glass is used in all Schmidt-Newtonian and Schmidt-Cassegrain 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 competing telescopes using soda lime glass. Individually Figured Optics Schmidt-Newtonian and Schmidt-Cassegrain corrector lenses and mirrors are individually figured to create a superior optical system, which is renowned for its exquisite smoothness and performance. Pyrex Primary Mirror Premium-grade Pyrex mirrors are used in all Schmidt-Newtonian and Schmidt-Cassegrain optical systems, providing exceptional thermal stability versus competing models using standard plate glass.
