9.Loosen the R.A. lock knob and carefully rotate the tele- scope 180° about the R.A. axis (Figure 18a &18b) This should be done as accurately as possible referencing the R.A. mechanical setting circle.

10.Adjust the position of the telescope in the Dec. axis so Polaris lies on the R.A. crosshairs of the illuminated reticle eyepiece (Figure 17).

11.Carefully push the telescope in horizontal motion while observing the movement of Polaris in the eyepiece field of
