title: Null test for wright telescope mirrors.
abstract: The Wright telescope is a variation of the Schmidt design which uses a corrector plate at the focus and whose primary mirror is an oblate spheroid. A null test for the mirror is described, which is a modification of the Foucault test, and which makes use of the properties of a particular reference ellipse.
