Reflecting telescope e.g. Schmidt-Cassegrain telescope, for e.g. planetary observation, has rotative system positioned at outlet of tube of telescope, where system has parabolic secondary convex mirror and 45 degree positioned flat mirror

摘要

The telescope has a rotative system positioned at the outlet of a tube of the telescope in an extension axis of the tube. The system includes a Cassegrain type aspherical or parabolic secondary convex mirror (2) and a 45 degree positioned flat mirror i.e. Newton secondary mirror (3). Luminous flow of an image collected by a reflecting primary concave mirror (1) is sent to the convex mirror (2). The mirror (2) is mounted on a common barrel fixed in a central orifice of a glass slide and locked by a washer. The system is maintained to stop through manual locking of a maintenance handle.
