Before securing the mount to the tripod as shown in Fig. 2-3: 1. Locate the Azimuth Adjustment Knobs from the box containing the CGEM mount. 2. Thread one knob into each of the holes located on either side of the mount. 3. Only thread the knobs about half way in, leaving enough space for the tripod Alignment Peg which will need to fit between the screw tips. Figure 2-2 Attaching the Equatorial Mount 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 CGEM 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: Equatorial Mount 1. Locate the azimuth adjustment screws on the equatorial mount. 2. Retract the screws so they do not 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.
