Maksutov’s cameras and telescopes

The third-order aberration formulae we have proposed in a previous paper, starting from Fermat’s principle and from the idea of stigmatic paths, are here applied to analyze and to project Maksutov’s cameras and Maksutov–Cassegrain’s telescopes. The final projects, since they take into account the thickness of lenses and the fifth-order aberrations, do not need any optimization procedure.
