Adjusting the Tripod Height

The tripod that comes with your CPC telescope is adjustable. To adjust 
the height at which the tripod stands:
1.  Loosen the extension clamp on one of the tripod legs (see figure 3-1).
2 .  Extend the leg to the desired height .
3 .  Tighten the extension clamp to hold the leg in place .
4 .  Repeat this process for each of the remaining legs making sure that 

the tripod is level when complete .

You can do this while the tripod legs are still folded together . 
Remember that the higher the tripod legs are extended, the less stable 
it is. For casual observing, this may not pose a problem. However, if 
you plan on doing photography, the tripod should be set low to ensure 
stability . A recommended height is to set the tripod in such a manner 
that you can look directly into the eyepiece on the telescope with a 
diagonal while seated . 

Attaching the CPC to the Tripod 

 

                   Mounting the Telescope

After the tripod is set up, you are now ready to attach the telescope .  
The bottom of the CPC base has three threaded holes that mount to the 
tripod head and one hole in the center that goes over the positioning pin 
on the tripod head .
1 .  Place the center hole in the bottom of the telescope base over the 

positioning pin in the center of the tripod head .

2 .  Rotate the telescope base on the tripod head until the three feet on 

the bottom of the base fall into the feet recesses on the top of the 
tripod head .

3 .  Thread the three attached mounting bolts from underneath the 

tripod head into the bottom of the telescope base . Tighten all  
three bolts .                     

You are now ready to attach the visual accessories onto the telescope 
optical tube .

Adjusting the Clutches

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 CPC has an altitude locking knob (right) located on the 
fork arm and an azimuth locking knob (left) located on the top 
of the base.

 Installing the Star Diagonal

The star diagonal is a prism or mirror that diverts the light at a right angle 
to the light path of the telescope .  This allows you to observe in positions 
that are physically more comfortable than if you looked straight through .  

To attach the 1.25” star diagonal onto the 8” optical tube:

1.25” Eyepiece

1.25”  

Star Diagonal

Visual Back

                   Visual accessories for the 8”

FIGURE 3-4

1 .  Turn the set screw 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 set screw on the visual back to hold the star diagonal  

in place .

If you wish to change the orientation of the star diagonal, loosen the set 
screw on the visual back until the star diagonal rotates freely . Rotate the 
diagonal to the desired position and tighten the set screw .

To attach the 2” star diagonal onto the 9.25/11” optical tubes:

1 .  Remove the visual back from the rear of the tube .
2 .  Attach the threaded ring of the 2” diagonal to the rear cell of  

the telescope .

3 .  Loosen the thumb screws on the side of the diagonal and remove the 

1 .25” adapter from the barrel of the diagonal .

If you wish to change the orientation of the 2” star diagonal, loosen 
the retaining ring that attaches the diagonal to the rear cell . Rotate the 
diagonal to the desired position and tighten the retaining ring .
