What if you need to aim the telescope directly north, but at an object that is nearer to the horizon than Polaris? You can’t do it with the counterweights down as pictured in Figure 1. Again, you have to rotate the scope in right ascension so that the counterweight shaft is positioned horizontally. Then rotate the scope in declination so it points to where you want it near the horizon.
To point the telescope directly south, the counterweight shaft should again be horizontal. Then you simply rotate the scope on the declination axis until it points in the south direction.
To point the telescope to the east or west, or in other directions, you rotate the telescope on its right ascension and declina- tion axes. Depending on the altitude of the object you want to observe, the counterweight shaft will be oriented somewhere between vertical and horizontal.
Figure 9 illustrates how the telescope will look when pointed at the four cardinal directions: north (Figure 9a), south (Figure 9b), east (Figure 9c) and west (Figure 9d).
The key things to remember when pointing the telescope are that a) you only move it in right ascension and declination, 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!

The Atlas
If you are using a portable battery like the Orion Dynamo, use the supplied 12V DC power cable (male cigarette lighter plug on one end, standard 12V DC power plug on the other end) to connect the battery to the 12V DC power jack on the faceplate of the mount (Figure 9.1). Make sure the Dynamo’s power switch is in the “on” position after connecting.
Functions of the Dual-Axis Hand Controller
There are three main categories of control buttons on the dual- axis controller (Figure 9.2).

Directional Buttons
The directional buttons allow complete control of the mounted telescope’s position during slewing or tracking. The Left and Right directional buttons control movements about the right ascension (R.A.). axis. The Up and Down directional buttons control movements about the declination (Dec.) axis.
