Developed by Astro-Tech to make large-format CCD imaging affordable for the amateur astronomer, the Astro-Tech AT10RCF is priced thousands of dollars less than the formerly least-expensive 10” R-C. The Astro-Tech AT10RCF is the first truly affordable large aperture true Ritchey-Chrétien astrograph available from a U. S. company. Even better, despite its low price, the Astro-Tech-developed AT10RCF has many of the same premium features as the much higher-priced competitive RCs (and some they don’t have) – like quartz mirrors, dielectric mirror coatings, carbon fiber body, and more.
