Page 25

Use the Utilities menu to perform many of AutoStar’s useful features, such as setting an alarm, adjust the display contrast, calculate the best eyepiece for viewing an object, set up your own landmark survey, and so forth.

Tip:

The Contrast Adjustment feature is usually only required in very cold weather.

If you adjust the contrast so that you can no longer read the display, turn off the power and turn it on again. When Version appears on the display (the initial display screens are not affected by the Contrast control), press MODE.

Tips:

To use the Landmark function, the telescope must be located and aligned exactly as when the landmark(s) was added to the database.

To add objects to the Landmark database, the telescope must be located and aligned exactly as when the original objects were added to the database.

JSet: Enter the time to be counted down, in hours, minutes and seconds, then press

ENTER.

JStart/Stop: Activates the timer set previously. Use the Scroll keys to toggle between ON and OFF. When ON is displayed, press ENTER to activate the timer. When the timer runs out, four beeps sound and the timer is deactivated.

Alarm selects a time for an alarm signal as a reminder. To use the Alarm, press ENTER, then choose "Set" or "Start/Stop."

JSet: Enter the time of day for the alarm to sound, in hours, minutes and seconds, then press ENTER.

JStart/Stop: Activates the alarm set previously. Use the Scroll keys to toggle between ON and OFF. When ON is displayed, press ENTER to activate the alarm. When the alarm time arrives, AutoStar beeps. Press ENTER to deactivate the alarm.

Eyepiece Calc calculates information about an eyepiece for the specific telescope to which AutoStar is connected.

JField of View: Scroll through a list of available eyepieces. When an eyepiece is selected, the field of view is calculated.

JMagnification: Scroll through a list of available eyepieces. When an eyepiece is selected, the magnification is calculated.

JSuggest: AutoStar calculates and suggests the best eyepiece for viewing, based on the telescope and the object being viewed.

Display Options enables or disables AutoStar’s two initial displays. If both displays are disabled, AutoStar begins with the Date display.

JSun Warning: Turns the SUN WARNING message on or off.

JGetting Started: Turns the GETTING STARTED message on or off.

Brightness Adj: Adjusts the brightness of the display using the Scroll keys. When complete, press ENTER.

Contrast Adj: Adjusts the contrast of the display using the Scroll keys. When complete, press ENTER.

NOTE: This feature is usually only required in very cold weather.

Beep: Turns the beep on or off.

Landmark Survey automatically slews the telescope to all user-defined landmarks with a short pause at each location. Press ENTER to start the survey. While a slew is in progress, press any key to skip that object and go to the next landmark on the list. To observe a landmark for a longer period, press MODE when paused on the object to stop the survey. Press ENTER to restart the survey at the first object on the list. See LANDMARKS, page 34, for information about creating a Landmark survey.

ETX-90PE specifications

The Meade ETX-90PE is a well-regarded telescope that combines portability and performance, making it a popular choice among both amateur astronomers and seasoned stargazers. Its compact design and advanced features make it an ideal instrument for those who seek to explore the night sky with ease.

At the heart of the ETX-90PE is its Maksutov-Cassegrain optical design, which utilizes a spherical primary mirror and a corrector lens to deliver exceptional image quality. With a focal length of 1250mm and a 90mm aperture, it strikes a balance between light-gathering ability and magnification, allowing users to observe celestial objects such as planets, star clusters, and distant galaxies in remarkable detail. The telescope's focal ratio of f/13.9 provides crisp and sharp views, making it particularly well-suited for planetary observation.

One of the standout features of the ETX-90PE is its Electronic Control System (ECS), which allows for easy and intuitive operation. The telescope is equipped with a built-in AutoStar Computerized GoTo mount, enabling users to locate and track over 30,000 celestial objects with just a few simple commands. With automatic alignment features, even beginners can get started quickly, making the wonders of the universe accessible to everyone.

Portability is a key characteristic of the Meade ETX-90PE. Weighing in at a mere 12.5 pounds, it can be easily transported to dark sky locations. Its compact design not only translates to ease of transport but also means it can be stored conveniently when not in use. The included sturdy aluminum tripod provides stable support, even during extended observation sessions.

The ETX-90PE further enhances the user experience with its high-quality accessories. It comes with a set of eyepieces, including a 26mm Super Plössl and a 9.7mm Plössl, allowing for various magnifications to suit different observing preferences. The telescope also features a built-in flip mirror, allowing for easier viewing through both the eyepiece and a camera, making astrophotography more accessible.

Additionally, the ETX-90PE is designed with user comfort in mind. The telescope offers adjustable slow-motion controls for fine-tuning views and an optical finder scope to help locate objects before zooming in. With robust construction, excellent optics, and a range of advanced features, the Meade ETX-90PE stands out as a versatile, high-quality telescope for both casual observers and serious astronomers alike. Its combination of technology and user-friendly functions makes it an enduring favorite for anyone looking to embark on a journey through the cosmos.
