11. Inser

t the eyepiece:

Remo

ve the supplied eyepiece (

Fig. 9

) from its container and place

it in the diagonal prism (

refractor models only; 1, Fig. 9) or directly into the eyepiece holder

(

2, Fig. 10, reflector models only). Tighten the thumbscrews (2 and 4, Fig. 9, refractor mod-

els only

) to a firm feel only. Tighten the thumbscrew (3 , Fig. 10, reflector models only) to a

fir

m feel only.

12.

Insert batteries: The telescope’s battery compartment (1, Fig. 11) is located on top of the

drive base. Open the battery compartment by lifting the cover and pulling it away from the

drive base.

Remove the battery holder from the compartment and carefully lift the 9v connector out

from the compar

tment. Take care not to accidentally detach the wires of the battery con-

nector from the base. Whenever you replace the batteries, to safeguard the wires, discon-

nect the 9v connector from the battery holder before removing the batteries.

Insert eight AA-size batteries into the battery holder, oriented as shown on the diagram on

the battery slots of the battery holder. Connect the 9v connector plug to the battery holder.

Carefully replace the battery holder back into the battery compartment. Replace the cover.

UTION:

Use care to install batter

ies as indicated by the battery compartment.

Follow battery manufacturer's precautions. Do not install batteries backwards or

mix new and used batteries. Do not mix battery types. If these precautions are not

followed, batteries may explode, catch fire, or leak. Improperly installed batteries

void your Meade warranty. Always remove the batteries if they are not to be used

for a long period of time.

14. Connect Autostar: Be certain that the power switch on the computer control panel is in

the OFF position. Plug the coil cord of the Autostar Controller into the HBX port

. Turn on

the power switch; the red LED lights when power is supplied to the panel. See

Fig. 12.

NOTE: The Autostar handbox does not require batteries; the telescope’s batteries

supply power to Autostar.

15. Remove the dust cover: Pull out the dust cover (12, Fig. 1) from the optical tube assem-

bly (13, Fig. 1).

Assembly of the basic telescope is now complete.

The Red Dot Viewfinder

Because the main telescope has a fairly narrow field of view, locating objects directly in the

main telescope can sometimes be difficult. The red dot viewfinder (Fig. 13) projects a small red

dot that permits you to more easily locate objects. When the red dot viewfinder and optical tube

are aligned to each other, both point to the same position in the sky. An object located in the

viewfinder is therefore in the eyepiece of the main telescope.

Aligning the Red Dot Viewfinder:

It is recommended that you perform steps 1 through 4 of this procedure during the daytime and

step 5 at night.

1. Loosen the tripod base lock knob (

26, Fig. 1) and the Altitude lock (10, Fig. 1), so that the

telescope can move freely.

2. If you have not already done so, place a low-power (e.g., 25mm) eyepiece in the diagonal

prism of the main telescope (

3, Fig. 1) and point the telescope at an easy-to-find land

object (

e.g., the top of a telephone pole or sign). Turn the focuser knob (1, Fig. 1) to focus

the image in the eyepiece. Center the object precisely.

3. Re-tighten the tripod base lock knob (

26, Fig. 1) and the Altitude lock (10, Fig. 1) so that the

telescope does not move during the procedure.

4. Slide the intensity slider to the right to turn the red dot viewfinder On (by changing the slid-

er’s position, you can change the intensity of the red dot; see

Fig. 13). Looking through the

viewfinder. Turn the viewfinder’s two alignment screws (

8, Fig. 1) until the viewfinder’s red

dot points precisely at the same object as centered in the e

epiece
