Abstract
Unlike traditional refracting telescopes, dialyte and Schupmann-medial refractors manage the correction of chromatic aberration through the use of correcting elements well spaced from their companion, single-element objectives. Dialyte designs leave a large contribution to lateral color, and Schupmann-medial types require the tilting of the mangin corrector to make the focus available, which restricts the field unless at least one toroidal curvature is included. A new dialyte design that combines attributes of both systems results in an all-refractive telescope that offers correction for lateral color and an accessible field unrestricted by tilt-induced astigmatism. The design can also be adapted to correct the secondary spectrum of a traditional achromat.
