An angular adjustment mechanism (11) for precisely adjusting an eyepiece (12) of an optical assembly (10) through the use of a parallel action joint lever system. The parallel action joint lever system acts to allow the eyepiece (12) and a mirror (24), disposed within the assembly (10), to rotate about a common axis (28), with the eyepiece (12) rotating at two times the angular speed of the mirror (24). The relative angular movement of the eyepiece (12) and the mirror (24) allows a user to obtain a comfortable viewing position without disturbing the alignment of the optical assembly (10). Furthermore, the relative angular movement of the eyepiece (12) and the mirror (24) does not effect the imaging of the optical assembly (10), or cause optical image shifts.
