Celestron C100ED-R, C80ED-R manual Attaching the Center Leg Brace, Installing the Counterweight Bar

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.

Attaching the Center Leg Brace

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.

Installing the Counterweight Bar
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		Mounting Knob

3. Tighten the counterweight bar lock nut fully for added			Central Rod

support (see fig 2-5).
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.
