A Schmidt camera is a type of telescope designed for wide-field astronomical imaging. It features a spherical mirror that collects light and a corrector plate that helps reduce optical distortions. This design allows astronomers to capture large areas of the night sky in a single image, making it ideal for surveys and studying celestial objects. The Schmidt camera was invented by Bernhard Schmidt in the 1930s. Its unique construction enables it to produce sharp images across a wide field of view, which is particularly useful for mapping star fields and discovering new celestial phenomena.
