Optical Correctors for Liquid Mirror Telescopes

One of the often cited limitations of liquid mirror telescopes pertains to the small region of sky which they can observe. Because the aberrations of a parabola increase rapidly with field angle, classical corrector designs cannot yield subarcsecond images for angles significantly greater than one degree. To access larger fields, innovative corrector designs must be explored.
In these pages we discuss the Optical Design and Testing of a family of two-mirror correctors to compensate the aberrations of a fixed parabolic mirror observing at a large angle from the zenith.
