Your telescope optical tube has a built on dovetail mounting bar used to attach the tube to the fork arm. To attach the
telescope tube:
1.
Loosen the tube clamp tightening knob.
2.
Slide the dovetail mounting bar of the telescope tube into the fork arm
clamp. Make sure that the logo on the side of the tube is right side up
when the tube is aligned with the fork arm.
3.
Tighten the tube clamp knob by hand to secure the tube to the fork arm.
Your NexStar is fully assembled and is ready to attach the accessories.

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 eyepiece adapter at the end of the focuser barrel until it no longer extends into (i.e.,
obstructs) the inner diameter of the focus barrel. Remove the protective dust cap from the focuser barrel.
2.
Slide the chrome portion of the star diagonal into the eyepiece adapter.
3.
Tighten the thumbscrew on the eyepiece adapter to hold the star diagonal in place.
If you wish to change the orientation of the star diagonal, loosen the thumbscrew on the eyepiece adapter until the star
diagonal rotates freely. Rotate the diagonal to the desired position and tighten the thumbscrew.
