An equatorial mount is simply an altazimuth mount tilted toward the celestial pole. The typical fork-mounted amateur telescope becomes equatorial when mounted on a wedge of the proper inclination, pointed north (or south in the Southern Hemisphere).
Well-made wedges are sturdy, easy to adjust, and heavy. To save weight and to take advantage of the vibration-damping properties of wood, I built the wooden wedge shown in Figure 9.4. Its obvious drawback is that there are no adjustments; the only way to adjust it is by moving the tripod legs or altering their length, and it only works at latitudes close to 34° north.
Would-be wedge builders should note that the mounting bolts of a Meade or Celestron telescope are not in an equilateral triangle. Measure their positions carefully before you drill the holes.
