RTT150 . ... The primary mirror 1 reflects light to the secondary mirror 2 which sends the converging beam of light to the system of four flat mirrors 3, 4, 5 and 6. That allows the beam of light to leave the telescope strictly along its polar axis and be collected in Coude focus. ... That's why at any tube position (for any rotation along the declination axis) beam of light parallel to the principal axis after reflection on mirror 3 follows the direction of declination axis. ...
