The latitude adjustment on the mount has a range from approximately 15° to 70°. It is best to always make final adjustments in latitude by moving the mount against gravity (i.e. using the rear latitude adjustment screw to raise the mount). Adjusting the Mount in Azimuth For rough adjustments in azimuth, simply pick up the telescope and tripod and move it side to side until it is roughly pointing towards north. For fine adjustments in azimuth: 1. Turn the azimuth adjustment knobs located on either side of the azimuth housing (see Fig 2-15). 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. Powering the Telescope The telescope mount can be powered by the supplied car battery adapter or optional 12v AC adapter. Use only adapters supplied by Celestron. Using any other adapter may damage the electronics or cause the telescope not to operate properly, and will void your manufacturer's warranty. 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). 2. Turn on the power to the telescope by flipping the switch, located on the electronics panel, to the "On" position. 15

The latitude adjustment on the mount has a range from approximately 15° to
70°.
It is best to always
make final adjustments in latitude by moving the mount against gravity (i.e. using the rear latitude
adjustment screw to raise the mount).
Adjusting the Mount in Azimuth
For rough adjustments in azimuth, simply pick up the telescope and tripod and move it side to side until it is roughly pointing
towards north.
For fine adjustments in azimuth:
1.
Turn the azimuth adjustment knobs located on either side of the azimuth housing (see Fig 2-15).
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.
Powering the Telescope
The telescope mount can be powered by the supplied car battery adapter or optional 12v AC adapter.
Use only adapters
supplied by Celestron.
Using any other adapter may damage the electronics or cause the telescope not to operate properly, and
will void
your manufacturer's warranty.
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
).
2.
Turn on the power to the telescope by flipping the switch,
located on the electronics panel, to the "On"
position.
