Imaging properties of several important reflectors

In this work we present the results of simulations of imaging properties of several important historical mirror telescopes constructed, Newton, Hadley, Herschel, Rosse
Schmidt-Cassegrain Telescopes

This paper describes analysis of residual aberrations of Schmidt-Cassegrain telescopes (SCT). Though SCTs have been produced for 30 years, problem of imaging properties is only rarely discussed. At first we have performed measurement of optical parameters of several commercially produced SCT telescopes of Meade, Celestron and Carl Zeiss Jena, then we have used measured data to construct the models of these system with the help of Zemax program and evaluate residual aberrations. We have found that it is possible to radically improve these systems by changing entry data.
