Query: A corrector design using active vase mirrors that allows a fixed
  telescope to access a large region of the sky   We investigate whether a three-mirror system, having secondary and the
tertiary mirrors with surfaces warped by Zernike polynomials generated by
active vase mirrors, is suitable to do the corrections of a fixed parabolic
mirror observing at large angles from the zenith. We obtain designs of
correctors with remarkable images and control of the distortion of the field of
the view contained within a field greater than 15 Deg.
