INTRODUCTION

A Meade ETXAstro Telescope is an extremely versatile, high-

resolution imaging system that, with advanced features similar

to larger and more specialized telescopes, can be used by

casual observers and serious astronomers alike. Wi t h

pushbutton controls, automatic tracking of celestial objects (with

one of the optional tripods), and diffraction-limited imaging, an

ETX telescope may be all the telescope ever required by many

terrestrial and astronomical observers.

As a first telescope, the ETX-90EC or ETX-125EC reveals

nature in an ever-expanding level of detail: observe the feather

structure of a bird from 50 yards or study the rings of the planet

Saturn from a distance of 800 million miles. Beyond the Solar

System observe nebulae, star clusters, galaxies, and other

deep-sky objects. Both telescopes are instruments fully capable

of growing with your interest.

Your Meade ETX Astro Telescope is one of the most

revolutionary telescope systems ever developed. Read this

manual thoroughly to take full advantage of the telescope’s

numerous advanced features.

This manual provides instructions for the following products:

• ETX-90EC Astro Telescope

• ETX-125EC Astro Telescope

The Electronic Controller

Control of both ETX model telescopes is through pushbutton

operation of the standard-equipment Electronic Controller

(Fig. 2). Nearly all functions of the telescope are accomplished

through the Electronic Controller with just a few button pushes:

• Move the telescope on two axes

(up-and-down or left-and-right)

any of 4 drive speeds for precise

tracking of astronomical or

terrestrial objects.

• Mount the telescope in the polar

mode for fully automatic tracking

of celestial objects using the

optional #880 (ETX–90EC), #881

(ETX-125EC) Table Tripod, or

#883 Deluxe Field Tripod (see

O P T I O N A L AC C E S S O R I E S

, page

17).

• When in the polar mode, switch

the motor drive between northern

and Southern Hemisphere oper-

ation for observing from any-

where in the world.

A detailed description of the functions and operation of the

Electronic Controller is found in E l e c t r onic Contro l l e r

Functions, page 6.

Parts List

In keeping with the ETX philosophy of elegant simplicity, an ETX

telescope is virtually completely assembled at the Meade

f a c t o r y. Getting the telescope ready for first observations

requires only a few minutes. When first opening the packing

box, note carefully the following parts:

• The ETX Astro Telescope with fork-mount system.

• Electronic Controller with attached coil cord.

• Viewfinder, packed in a separate small box.

• Super Plössl (SP) 26mm eyepiece, packed in a plastic

storage container, in a separate small box.

• Hex-wrench set (2 wrenches), packed with the manual.

The viewfinder is packed separately from the main telescope to

avoid the possibility of the viewfinder slipping in its bracket and

scratching the viewfinder tube during shipment.

Assembly Instructions

Assembly of both ETX model telescopes requires eight (user-

supplied) AA-size batteries and the following steps:

1. a.

ETX-90EC

8 x 21mm Viewfinder: Slide the eyepiece end

of the viewfinder through the front of the viewfinder

bracket (1, Fig. 3).

ETX-125EC

8 x 25mm Right-Angle Viewfinder: Slide the

front cell end of the right-angle viewfinder through the rear

of the viewfinder bracket (2, Fig. 3).

You may need to unthread the six alignment screws slightly

to fit the viewfinder through the bracket. With the viewfinder

in place, tighten (to a firm feel only) the six alignment screws

against the viewfinder tube. To align the viewfinder, see page

2. Remove the SP26mm eyepiece (1, Fig. 1) from its container

and place it in the eyepiece holder (4, Fig. 1). Tighten the

thumbscrew (3, Fig. 1) to a firm feel only.

3. The telescope’s battery compartment (6, Fig. 4) is at the

bottom of the drive base. Place the telescope securely on its

side as shown in Fig. 4. Open the battery compartment by

simultaneously depressing the two release latches (4, Fig. 4)

and pulling the battery cover (5, Fig. 4) away from the drive

base. Insert eight AA-size batteries into the battery

compartment, oriented as shown on the battery mounting

board. Put the cover back in place.

4. Place the telescope in an upright position on a flat surface.

Be certain that the power switch on the computer control

panel (1, Fig. 5) is in the OFF position. Plug the coil cord for

the Electronic Controller into the HBX port (3, Fig. 5).

Basic assembly of either ETX model is now complete.
