The results expected from the use of telescope field correctors with higher resolution than previously available at observatories with greatly improved atmospheric seeing is examined. Calculations reveal that spaced triplet correctors with spherical surfaces can reduce image spread to within 0.25 arcsec over a field of up to plus or minus 10 arcmin and a spectral range of 365-852 nm for the paraboloid mirror of the Isaac Newton 2.5-m telescope. A lens triplet consisting of a negative lens situated between two positive lenses of unequal power, or the reverse, is shown to reduce geometrical image spread to within 0.3 arcsec under the same conditions for the Ritchey-Chretien prime mirror of the Anglo-Australian 154-in. telescope.
