Abstract

8089. Zeiss, C., [Firm of]. April 21, 1910, [Convention date]. Telescopes. - In multiple-power telescopes, a Galilean telescope system b c is mounted reversibly in front of the objective a, of a telescope with an advanced entrance pupil made to coincide approximately with the exit pupil of the Galilean system. Fig. 3 shows the system b, c mounted in a casing e rotatable through 180 degrees in front of the ocular a of a broken telescope, the entrance pupil of which is situated practically at the position of the reflecting- prism d.
