The CPC has a dual axis clutch system. This allows you to move the telescope manually even when the telescope is not powered on.
However, both clutches need to be tightened down for the telescope to be aligned for "goto" use. Any manual movement of the
telescope will invalidate your telescope's alignment.
Before attaching your visual accessories, first loosen the altitude locking knob while holding the telescope tube by the rear cell handle.
Rotate the tube upwards until it is level with the ground and tighten the locking knob.
Note: When transporting your telescope, make sure that both clutches are somewhat loose; this will diminish the load placed on
the worm gear assemblies and protect them from damage.

The star diagonal diverts the light at a right angle from the light path of the telescope. For astronomical observing, this allows you to
observe in positions that are more comfortable than if you were to look straight through. To attach the star diagonal:
1.
Turn the thumbscrew on the visual back until its tip no longer
extends into (i.e., obstructs) the inner diameter of the visual back.
2.
Slide the chrome portion of the star diagonal into the visual back.
3.
Tighten the thumbscrew on the visual back to hold the star
.
diagonal in place
If you wish to change the orientation of the star diagonal, loosen
the thumbscrew on the visual back until the star diagonal rotates
freely. Rotate the diagonal to the desired position and tighten the
thumbscrew.
