title: New version of solid telescope.
abstract: This paper describes a new optical concept for a telescope. It is essentially made by a single refractive element used in a nontraditional way. The telescope is based upon the internal and multiple reflections over the surfaces of this refractive element. It offers important advantages in the alignment and stability. In this paper, some representative configurations of telescope and a focal adapter based on the same concept are presented, trying to underline the main advantages. A brief in-depth description of the performances is reported.
