Instructions / Assembly

ETX 90 USERS ONLY: Remove the end nut from the

spreader shaft and slide the spreader in between the

telescope legs. Attach the end nut and hand tighten

until the telescope legs are held snuggly in the most

spread position. Position the tripod where you want the

telescope to be and check that the top of the tripod is

approximately level. Use the included bubble level/

compass to level the tripod head.

Mounting the Telescope

4 ETX 80 USERS ONLY: Thread the supplied bolts

about two or three turns through the underside of

the telescope base. Line up the bolts over the key-

like holes on the top of the tripod and slide the bolts

into the holes. Rotate the telescope counter-clockwise

GETTING STARTED

until the bolts t into the hole bays. Then, reach under

the tripod base and tighten the bolts to a rm feel.

ETX 90 USERS ONLY: On the tripod, loosen the

latitude control knob and lift up the tilt-plate so that you

can easily access the underside of the plate. Re-lock

the latitude control knob, so the assembly doesn’t slip

while you are attaching the telescope.

Take the ETX 90 from its packaging and line up the

mounting holes on the base of the telescope with the

tripod attachment knobs. Thread both attachment

knobs into the base of the telescope. Tighten to a rm

feel only.

Unlock the latitude control knob and lower the tilt-plate

until it is level (push the tilt-plate down until it stops;

this is the level position). Lock the latitude control

knob.

Installing the Batteries

5 Lift the battery cover located in between the mount

fork arms. Gently remove the battery holder from the

compartment so you don’t accidentally pull out the

wires attached to the holder. Insert 6 user supplied

“AA” batteries in the holder. Refer to the diagram on

the holder to orient the batteries properly Replace the

holder back into the battery compartment and replace
