Introduction
This manual describes applications of the Autostar Computer
Controller with various models of Meade telescopes:
ETX-90EC: Refer to the manual included with the ETX-90EC for
instructions on the basic operation of the telescope, including usage
of the standard-equipment Electronic Controller (EC).
DS-telescopes (e.g., DS-60, DS-70, etc.): (a) Refer to the manual
included with each of these models for instructions on the basic
operation of the telescope. (b) If you purchased a DS-model which
includes the #492 Dual-Motor Electronic Control System, then
interchange the Electronic Controller (EC) of the #492 System with
the Autostar Computer Controller and follow the instructions in this
manual. The Autostar handbox plugs into the same “HBX” connector
on the telescope as the EC handbox. (c) If your DS-model did not
originally include the #492 System, and you are now adding the
complete #493 Autostar Computer Control System (including motors
on both axes) to your telescope, then read the enclosed manual
(“Meade #493 Autostar Computer Control System”) first, before
reading this manual.
Autostar assists the observer with a large variety of features,
including:
• Control the movement of the telescope to locate terrestrial and
astronomical objects.
• Catalog of events (e.g., Moon phases, meteor showers, etc.).
WARNING: Never use Autostar to move a telescope to look at
the Sun! Looking at or near the Sun will cause instant and
irreversible damage to your eye. Eye damage is often
painless, so there is no warning to the observer that damage
has occurred until it is too late. Do not point a telescope or its
viewfinder at or near the Sun. Do not look through a telescope
or its viewfinder as it is moving. Children should always have
adult supervision while observing.
