Figure 19. Screws for CW shaft tilting

Figure 20. Tilt the counterweight shaft for low

altitude

DO NOT rock the counterweight shaft rigorously. It may damage the worm system.

STEP 5. Install the Counterweight(s) and Telescope

Before putting on CW, make sure the mount is at its zero position, i.e., CW shaft points to the

ground. Disengage the R.A. Gear Switch to set the R.A. axis free before loading the CW.

Remove the CW Safety Cap at the end of CW Shaft. Glide the CW over the shaft with the larger hole

opening facing down. Place the Safety Cap back onto the shaft. Move the CW to the bottom of the

shaft and tighten the CW locking Screw.

Figure 21. Loading counterweight

You may need more CW for heavier payloads, or a smaller CW for lighter scopes.

CEM70 is equipped with a Vixen/Losmandy-D dual saddle. It can receive either a Vixen or a

Losmandy-D plate. Release the dovetail saddle locking knobs and slide the telescope dovetail plate

into the saddle. Tighten the saddle locking knobs.
