9 Optional Motor Drives for Automatic T racking An optional DC motor drive can be mounted on the R.A. axis of the equatorial mount to provide hands-free trac king. Objects will then remain stationar y in the field of vie w without any manual adjustment of the R.
10 the counterweight shaft will be or iented somewhere between vertical and hor iz ontal. The ke y things to remember when pointing the telescope is that a) you only mov e it in R.A. and Dec., not in azimuth or latitude (altitude), and b) the counterweight and shaft will not alwa ys appear as it does in Figure 1.
11 If the entire primar y mirror reflection is not visib le in the sec- ondar y mirror , as in Figure 8c, you will need to adjust the tilt of the secondar y mirror . This is done by alter nately loosening one of the three alignment setscrews while tightening the other two , as depicted in Figure 10.

In very cold climates (below freezing), it is essential to store the telescope as cold as possible. If it has to adjust to more than a 40° temperature change, allo w at least one hour .
