On either side of the mount, just below the DEC setting circle, there are two

shafts that extend out about 1/2". These are the R.A. shafts (see figure 2-7).
The R.A. slow motion knob has a small metal sleeve that fits over the R.A.
shaft. To install the R.A. slow motion knob:

As mentioned above, there are two R.A. shafts, one on either side of the
Shaft
mount. It makes no difference which shaft you put it on since both work the
same. Use whichever one you find more convenient. If, after a few observ-
ing sessions, you find the R.A. slow motion knob is more accessible from the
other side, go ahead and move it.
