To point the telescope to the east or west, or in other direc-
tions, you rotate the telescope on its R.A. and Dec. axes.
Depending on the altitude of the object you want to observe,
the counterweight shaft will be oriented somewhere between
vertical and horizontal. 

Figure 6 illustrates how the telescope will look pointed at the
four cardinal directions - north, south, east, and west

The key things to remember when pointing the telescope is that
a) you only move it in R.A. and Dec., not in azimuth or latitude
(altitude), and b) the counterweight and shaft will not always
appear as it does in Figure 1. In fact, it almost never will!

Figure 6A, 6B, 6C, 6D: This illustration shows the
telescope pointed in the four cardinal directions: (a)
north, (b) south, (c) east, (d) west. Note that the tripod
and mount have not been moved; only the telescope
tube has been moved on the R.A. and Dec. axes.
