6. Place the entire telescope onto the top of the tripod head, and insert the threaded rod into
the central hole in the bottom of the drive base of the telescope. Tighten the tension knob
(3, Fig. 3); firm tightening of the tension knob is sufficient to result in rigid positioning of the
tripod legs.
7. To vary the tripod height, loosen the 6 lock-knobs, slide the 3 inner tripod leg sections out
to the desired height, and firmly re-tighten (but do not overtighten) the 6 lock-knobs.
To collapse the tripod (after removing the telescope and equatorial wedge, if applicable) for
storage follow these steps:
1. Rotate the spreader bar 60° from its assembled position, so that one spreader bar arm is
located between each adjacent pair of tripod legs.
2. At the base of the tripod is a 3-vane extension strut system, with a circular hub at its
center (6, Fig. 3). Grasp the tripod head (1, Fig. 3) with one hand and, with the other hand,
pull directly "up" on the central hub of the extension strut system. This operation will cause
the tripod legs to move inward to a collapsed position.
Precautionary notes for the tripod
• If the tripod does not seem to extend or collapse easily, do not force the tripod legs in or
out. By following the instructions above, the tripod will function properly, but if you are
unclear on the proper procedure, forcing the tripod into an incorrect position may damage
the extension strut system.
• Be sure the spreader bar (4, Fig. 3) is not upside-down on the threaded rod.

How to Assemble Your Telescope

Assembly of the LX90 telescope requires eight C-cell (user-supplied) batteries or optional
power cords (25') to a standard 115v home outlet or to a 12v DC automobile cigarette lighter
plug. See the Instruction Sheets supplied with the optional power cords for installation
information. To install batteries:
1. Unlock the Dec lock (6, Fig. 1) to move the optical tube (5, Fig. 1) through the fork arms.
Move the optical tube to the position depicted in Fig. 1 (top image) and relock the Dec lock.
2. Remove the battery compartment covers (16, Fig. 1) and carefully remove the battery
holder, being mindful of the connector wires. Insert four C-cell batteries into each battery
holder, oriented as shown on the diagram on the battery slots inside the battery holder.
Return the battery holders to their respective compartments and replace the covers.
See Fig. 5 for the proper orientation of the holder. Do not force the holder into the battery
compartment. If a holder does not slip easily into the compartment, you may have
inserted the holder incorrectly. Replace the compartment covers when you are done.
CAUTION: Use care to install batteries 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.
3. Be certain that the power switch on the computer control panel (13C, Fig. 1) is in the OFF
position. Plug the SmartFinder coil cord into one of the AUX ports (13D, Fig. 1) on the
computer control panel. Plug the coil cord of the AutoStar Controller into the HBX port
(13A, Fig. 1 ).
NOTE: AutoStar does not require batteries; the telescope's batteries supply power
to AutoStar.
4. Remove the dust cap from the rear cell of the telescope. Thread the eyepiece holder into
the rear cell thread. Slide the diagonal prism into the eyepiece holder and lock in place by
turning the thumbscrew to a firm feel.
5. Remove the Super Plössl 26mm eyepiece (1, Fig. 1) from its container and place it in the
diagonal prism (3, Fig. 1 ). Tighten the thumbscrew (2, Fig. 1) to a firm feel only.
6. Remove the dust cover (15, Fig. 1) from the optical tube assembly (5, Fig. 1) by gently
prying it off.
Looking at or near the Sun will cause irreversable damage to your eye. Do not point this telescope at or near the
Sun. Do not look through the telescope as it is moving.
