Description

An adjustable coma and astigmatism corrector, using two small simple lenses, and suitable for correcting the image of an off-axis guide star up to about 10 from the axis of a paraboloidal reflector, is described. The on-axis image is not obscured, and retains its seeing-limited quality, achromatism and high efficiency. (author)
