Abstract
A scanning wide-field telescope includes a primary reflecting mirror and a corrector assembly. The corrector assembly corrects light beams for spherical aberration imposed on the light beams by the primary reflecting mirror. The corrector assembly is located between the primary reflecting mirror and a viewing end of the telescope, and is configured to move to multiple optical focal points of the primary reflecting mirror.
