polar axis. Rotate the telescope about the polar axis so that the Counterweight Shaft (7) is parallel to the ground (horizontal).

Loosen the Counterweight Lock Screw (located on the counterweight), and slide the Counterweight (6) along the shaft until the telescope remains stationary without drifting rotationally about the polar axis. Tighten the Counterweight Lock Screw, locking the Counterweight into position.

Now balance the telescope about the Declination Axis (3) . Loosen the declination lock screw and the Cradle Lock Screws so that the telescope can slide freely inside the Cradles. Slide the telescope up or down inside the rings until the telescope remains stationary without drifting rotationally about the Declination Axis. Tighten Cradle Lock Screws. The telescope is now balanced.
