Paper Abstract

Rays from a given point on a celestial object will traverse different paths through the atmosphere due to atmospheric dispersion. They will therefore suffer different phase distortions due to atmospheric turbulence. When the mean distortion is corrected by a compensated imaging system a residual error, which is a function of spectral bandwidth, will remain. This error grows as sec4/3 tanS/6, where c is the zenith angle, and will limit the region of the sky over which satisfactory compensation is possible.
