The equatorial mount allows you to tilt the telescope’s axis of
rotation so that you can track the stars as they move across the
sky. The CG-5 mount is a German equatorial mount that
attaches to the tripod head. On one side of the tripod head there
is a metal alignment peg for aligning the mount. This side of
the tripod will face north when setting up for an astronomical
observing session. To attach the equatorial head:
1. Locate the azimuth adjustment screws on the equatorial mount.
2. Retract the screws so they no longer extend into the azimuth
housing on the mount. Do NOT remove the screws since
they are needed later for polar alignment.
3. Hold the equatorial mount over the tripod head so that the
azimuth housing is above the metal peg.
4. Place the equatorial mount on the tripod head so that the two
are flush.
5. Tighten the knob (attached to the central rod) on the underside
of the tripod head to hold the equatorial mount firmly in place.

1. Slide the accessory tray over the central rod so that each arm of the tray is pushing against the inside of the tripod
legs.
2. Thread the accessory tray knob on to the central rod and tighten.

To properly balance the telescope, the mount comes
with a counterweight bar and at least one
counterweight (depending on model). To install the
counterweight bar:
1. Locate the opening in the equatorial mount on the
DEC axis
2. Thread the counterweight bar into the opening until
tight.
3. Tighten the counterweight bar lock nut fully for added
support.
Once the bar is securely in place you are ready to attach the
counterweight.
Since the fully assembled telescope can be quite heavy, position the mount so that the polar axis is pointing
towards north before the tube assembly and counterweights are attached. This will make the polar alignment
procedure much easier.
