Adjusting the Mount in Azimuth

Figure 2-15

latitude screw, first use the rear screw to raise the mount head all the way up. Then remove the front latitude screw completely. Now you should be able to manually move the mount head all the way to its lowest latitude. Now, using only the rear screw, raise the mount to your desired latitude.

For rough adjustments in azimuth, simply pick up the telescope and tripod and move it. For fine adjustments in azimuth:

1.Turn the azimuth adjustment knobs located on either side of the azimuth housing (see Fig 2-14). While standing behind the telescope, the knobs are on the front of the mount.

•Turning the right adjustment knob clockwise moves the mount toward the right.

•Turning the left adjustment knob clockwise moves the mount to the left.

Both screws push off of the peg on the tripod head, which means you may have to loosen one screw while tightening the other. The screw that holds the equatorial mount to the tripod may have to be loosened slightly.

Keep in mind that adjusting the mount is done during the polar alignment process only. Once polar aligned, the mount must NOT be moved. Pointing the telescope is done by moving the mount in right ascension and declination, as described earlier in this manual.

Attaching the Declination Cable (For GT Models Only)

The Advanced Series mount comes with a declination cable that connects from the R.A. motor drive electronic panel to the Dec motor drive. To attach the motor cable:

Locate the Declination cable and plug one end of

DEC Locking

the cable into the port on the electronics panel

Clamp

labeled DEC Port and plug the other end of the

cable into the port located on the declination

motor drive (see Fig 2-15).

On/Off Switch

1.To power the telescope with the car battery adapter (or 12v AC adapter), simply plug the round post into the 12v

outlet on the electronic panel and plug the other end into your cars cigarette

lighter outlet or portable power supply (see Optional Accessories). Note: to prevent the power cord from being accidentally pulled out, wrap the power cord around the strain relief located below the power switch.

2.Turn on the power to the telescope by flipping the switch, located on the electronics panel, to the "On" position.
