aplanatic telescope

An aplanatic telescope is designed to produce clearer, sharper images by minimizing optical distortions known as spherical and coma aberrations. It accomplishes this by carefully shaping its mirrors so that light rays from a distant object focus precisely at a single point without blurring or distortions. This results in higher image quality across the entire field of view, making it ideal for detailed observations in astronomy. Essentially, an aplanatic design ensures that what you see through the telescope is an accurate and crisp representation of the celestial object.
