The SPACE LAUNCHER Alt-Az mount is easy to move wherever you want to point it. For the 60AZ
and 76AZ the
up and down (altitude) is controlled by the altitude locking knob (Figure 2-12). The side-to-side (azimuth) is
controlled by the azimuth lock (Figure 2-12). When both knobs are loose you can find your objects easily (through
the finderscope) and then lock the controls.
For fine adjustments in altitude, you turn the knurled ring of the altitude slow motion rod (when the altitude lock is
tight) in either direction – see Figure 2-9.
Note:
Before tightening the altitude locking knob, the location you are
seeking should be located in the finderscope.

The diagonal is a prism that diverts the light at a right angle to the light path of
the refractor. This allows you to observe in a position that is more comfortable
than if you had to look straight through. This diagonal is an erect image model
that corrects the image to be right side up and oriented correctly left-to-right
which is much easier to use for terrestrial observing. Also, the diagonal can be
rotated to any position which is most favorable for you. To install the diagonal
and eyepiece:
1.
Insert the small barrel of the diagonal into the 1.25” eyepiece adapter of
the focus tube on the refractor – Figure 2-13. Make sure the two
thumbscrews on the eyepiece adapter do not protrude into the focuser
tube before installation and the plug up cap is removed from the
eyepiece adapter.
2.
Put the chrome barrel end of one of the eyepieces into the diagonal and
tighten the thumb screw. Again, when doing this make sure the
thumbscrew is not protruding into the diagonal before inserting the
eyepiece.
3.
The eyepieces can be changed to other focal lengths by reversing the procedure in step 2 above.

The diagonal for the 50AZ is called a star diagonal where the prism corrects the
image to be right side up (erect image) but the image is reversed left-to-right. The
diagonal and eyepieces are .96” diameter sizes. All steps above are the same with
the 50AZ.
