Abstract
The Schmidt camera with an achromatic corrector is an excellent survey instrument, but is impractical in sizes much larger than the Palomar and UK Schmidts, because of the size of the dome required. Other one- and two-mirror systems also suffer from limitations of focal ratio, field or tube length. Three-mirror systems show more promise, and some previous designs are described. A new design of survey telescope is presented which is more compact, has a larger relative aperture, and has a larger field than most earlier designs. A large central obscuration is its weakest feature.Keywords
