Question

Quizplus · Accepted Answer

The Schmidt telescope uses a concave, spherical primary mirror along with a glass corrector plate at the telescope's entrance to correct for spherical aberration, a common issue with simple mirror designs. This configuration allows for wide-field optical observations with minimal distortion.
