Movement scheme of the gimbal: Panel (A) the assembled motion component scheme with the rotation axes, (C) is the mounted sclera, (D) is the axis for motorized rotation about the optical axis (equatorial), (E) is the manual rotation axis for installation of the sprocket for axis (D), and (F) is the motorized axis for lateral rotation (meridional). Note that as rotation occurs about (F), the (D) axis is rotated about (F), as well. Panel (B) is an isometric exploded view of the mounting scheme to the motion components. (C) is the sclera and (D) is the centerline for rotation about the optical axis.
