Ritchey-Chrétien Telescope
A Ritchey-Chrétien telescope is a specialized type of reflecting telescope designed for high-precision astronomy. It uses two hyperbolic mirrors—one large primary mirror and a smaller secondary mirror—to eliminate common optical distortions like coma and spherical aberration. This design produces sharp, wide-field images with minimal distortion, making it ideal for astrophotography and detailed celestial observations. Its lack of central obstruction, compared to other telescopes, enhances image clarity and contrast. Popular among professional observatories and advanced amateurs, the Ritchey-Chrétien telescope provides excellent image quality across a broad field of view, enabling detailed study of planets, stars, and galaxies.
