Laurent Cassegrain

The Laurent Cassegrain is a type of telescope design that uses two mirrors to focus light. It features a concave primary mirror and a convex secondary mirror that bounce light back through a hole in the primary to the eyepiece or camera. This configuration allows for a compact, high-magnification instrument with minimal optical aberrations. It is commonly used in astronomical telescopes for detailed observation of stars, planets, and deep-sky objects due to its effective light-gathering and image-sharpening capabilities.
