The Ritchey-Chrétien telescope is the most popular optical design used by professional astronomers and astroimagers all over the world. The Hubble Space Telescope itself uses the RC configuration.

All new GSO RC telescopes now come with a focuser upgrade kit allowing you to connect the ZWO & QHY EAF focusers without additional modification.

The Guan Sheng Optical RC's are excellent astrographs with solid build quality and precisely-figured optical surfaces. The concave hyperbolic primary and convex secondary mirrors deliver excellent correction across the field. The low thermal expansion quartz mirrors have a surface correction of 1/12th Lambda PV or better and have highly reflective dielectric coatings ensuring 99% reflectivity.

The telescope is made with a lightweight and rigid carbon fibre tube and features computer-optimized baffles to eliminate stray light.

The 8" f/8 Ritchey-Chrétien comes with a dual-speed 2" 10:1 Crayford focuser with 50mm of focus travel and includes a 1.25" adapter and a selection of 2" & 1" extension rings to make connecting a variety of imaging accessories straightforward.

The TS-Optics 2" 1x Flattener for RCs is compatible with both the 6" and 8" GSO RC telescopes.
