A television projection system for producing an enlarged television image on a projection screen positionally located at a remote point from a standard television set. A tubular housing is mounted adjacent to a cathode ray tube screen of the television set. The tubular housing extends in a longitudinal direction and includes a first end having a lens tube housing displaceably movable with respect to the overall tubular housing. The lens tube housing contains a single plano-convex lens element which is utilized for enlarging the image produced from the cathode ray tube screen onto the remotely located projection screen. A switching element comprising a double throw, double pole switch is mounted on the television set and electrically coupled to the vertical deflection circuit in order to provide a vertically inverted and transversely reversed image. The inverted and reversed image is passed through the plano-convex lens where it is inverted and reversed to provide an appropriate image on the projection screen.
