INTRODUCTION

The ETX90 Telescope
An advanced, computer-controlled telescope system
Congratulations on receiving your new ETX90 telescope. You'll find that this telescope system has all you need
to explore the Universe we live in. Meade's concept was to create a telescope that would be simple enough for
anyone to use, yet capable enough for the experienced amateur to stretch their knowledge and skills. With the
ETX's' advanced set of features, you will have plenty of room to learn and expand your interest in astronomy and
not out grow your telescope. Here are a few of the features that set the Meade ETX90 telescope system apart
from all others.
Optics: ETX Maksutov-Cassegrain telescopes produce superlative, diffraction-limited optical performance
and resolution. Optics so high in contrast, image brightness, and resolution that the ETX90 optical
system often outperforms many telescopes of larger apertures.
Mechanics: Fork Mounts with standard-equipment dual-axis drive system and #497 AutoStar Controller. The
rigid fork mountings of the ETX Maksutov-Cassegrain telescope include high-torque DC motors on
both telescope axes.
Computer: The AutoStar #497 handbox gives you complete control of your ETX90 system from the palm of
your hand. With a database of over 30,000 objects, you will never run out of things to explore. With
the telescope placed in the altazimuth mode, astronomical object-tracking may be accomplished
automatically, after a quick and easy 2-minute alignment on the night sky.
If you are like us, you can't wait to get outside under a dark sky to try out your new ETX90 telescope. We have
provided a Getting Started Guide that will get you up and running in the shortest amount of time possible. After
your first experience, please sit down with this manual and read about all the advanced features that are available
to you with this telescope system. We are confident that the ETX90 will keep you fascinated with the Universe and
entertained for many years to come.
Clear Skies,
The people at Meade
