Abstract

A penta mirror diagonal and zoom lens assembly for refracting or catadioptric astronomical telescopes includes a specially adapted zoom lens with a key extending outward from an objective lens and an adaptor designed for insertion and retention in a viewing end of an astronomical or catadioptric telescope. The adaptor includes a keyway which mates with the key on the zoom lens, thus allowing the zoom lens to be used only with the adaptor. The zoom lens itself is specially designed for use with astronomical or catadioptric telescopes.
