a. If the star drifts South (or down), the telescope's
polar axis is pointing too far East (Fig. 22) b. If the star drifts North (or up), the telescope's
polar axis is pointing too far West (Fig. 23).
4. Move the wedge in azimuth (horizontally) to effect the appropriate change in polar alignment. Reposition
the telescope's East-West polar axis orientation until there is no further North-South drift by the star. Track
the star for a period of time to be certain that its Declination drift has ceased. (Please note that Figs. 22, 23,
24, and 25 show the telescope pointed in the 90 degree position, and not the 0 degree position that is
required for "Drift" method alignment. This is done to illustrate the position of the pole star relative to the
polar axis of the telescope.)
5. Next, point the telescope at another moderately bright star near the Eastern horizon, but still near the
celestial equator. For best results, the star should be about 20° or 30° above the Eastern horizon and
within ± 5° of the celestial equator.
6. Again note the extent of the star's drift in Declination:
a. If the star drifts South, (or down) the telescope's
polar axis is pointing too low (Fig. 24). b. If the star drifts North, (or up) the telescope's
polar axis is pointing too high (Fig. 25).
7. Use the latitude angle fine-adjust control on the wedge to effect the appropriate change in latitude angle,
