The AstroMaster Alt-Az mount is easy to move wherever you want to point it . The up and down (altitude) is controlled by the
pan handle (Figure 2-10) . The side-to-side (azimuth) is controlled by the azimuth lock (Figure 2-9) . The pan handle and the
azimuth lock are both loosened by turning the handle and lock counterclockwise . When loose you can find your objects easily
and then lock the controls . To lock the controls in place, turn them clockwise .

INSTALLING THE TELESCOPE TUBE TO THE MOUNT

The telescope optical tube attaches to the mount via a dovetail slide bar mounting bracket at the top of the mount (Figure
2-11) . The mounting bar is attached along the bottom of the telescope tube . Before you attach the optical tube, make sure
that the pan handle and azimuth lock are fully locked . Then put the dovetail bracket in the horizontal position as shown in
Figure 2-10 . This will ensure that the mount does not move suddenly while attaching the telescope optical tube . Also, remove
the objective lens . To mount the telescope tube:
1 . Remove the protective paper covering the optical tube .
2 . Loosen the mounting knob and the mounting safety screw on the side of the dovetail mounting platform so they do not
protrude into the mounting platform – see Figure 2-11 .
3 . Slide the dovetail mounting bar into the recess on the top of the mounting platform (Figure 2-12) .
4 . Tighten the mounting knob on the dovetail mounting platform to hold the telescope in place .
5 . Hand tighten the mounting platform safety screw until the tip touches the side of the mounting bracket .
NOTE: Never loosen any of the knobs on the telescope tube or mount other than the azimuth and altitude knobs .
