Schmidt Camera is a type of telescope that has a spherical primary mirror and a corrector plate that is placed in front of it. The corrector plate corrects the spherical aberration that is caused by the spherical primary mirror. The term "Schmidt Camera" is named after Bernhard Schmidt, who invented the telescope in 1931. There are several synonyms for the term "Schmidt Camera" such as the "Schmidt Telescope," "Schmidt Optics," and "Schmidt Corrector." The Schmidt Camera is popular among amateur astronomers because of its compact size and high-quality optics. It can be used for a variety of astronomical observations, including deep space photography.
