Meade ETX-90PE instruction manual Object Menu options include, Observing Satellites? See

Page 23

Use the OBJECT menu to select an object from the database.

When your telescope is aligned and you select an object from any of these lists, you just need to press the GO TO key to move the telescope so that it is pointed at the selected object.

Over 30,000 objects are available for ETX-90PE, ETX-105PE and ETX- 125PE models.

The available objects include planets, constellations, individual stars, double stars, star clusters, galaxies, quasars, satellites, asteroids and comets.

Also, try out the Guided Tour feature; the “Tonight’s Best” Guided Tour will point your telescope at the best objects visible in the sky for every given night of the year.

Object Menu

Almost all observing with AutoStar is performed using the Object menu category. (The two exceptions are the Guided Tours and Landmark Survey.) See GO TO SATURN, page 19, for an example of observing using the Object menu. Also see USING THE GUIDED TOUR, page 19.

Many AutoStar menu categories contain lists or databases. The AutoStar object data- base is a list of viewable objects, such as stars, planets, comets, nebulae and so forth. When one of these objects is selected from the object database and is above the hori- zon, AutoStar moves your telescope (if properly aligned) and points it at the selected object.

Note: Most celestial objects are visible in the sky for only part of the night and also only visible part of the year. If an object is not visible on the night you are observing, AutoStar displays a message that the object is below the horizon.

The Object Menu options include:

Solar System is a database of the eight planets (Earth is not included) in order out from the Sun, followed by the Moon, asteroids and comets.

Constellation is a database of all 88 Northern and Southern Hemisphere constellations. To use this menu:

1.When this menu option is chosen and “Andromeda” displays, use the Scroll keys to scroll through the constellation list.

2.Press ENTER to select a constellation and to display the coordinates of the con- stellation. Press one of the Scroll keys and information about the constellation will scroll across the display screen.

3.Press GO TO to display the list of stars in the constellation. Use the Scroll keys to scroll through the list of stars in the constellation, from the brightest to dimmest.

4.Press ENTER to select a star and use the Scroll keys to display information about the star. Press GO TO again to slew the telescope to that star.

Note: Use MODE to abort any of these operations.

Deep Sky is a database of objects outside our Solar System such as nebulas, star clusters, galaxies and quasars.

Star is a database of stars listed in different categories such as named, double, variable or nearby.

Satellite is a database of Earth-orbiting objects such as the International Space Station, the Hubble Space Telescope, Global Positioning System (GPS) satellites and geosynchronous orbit satellites.

User Objects allows the user to define and store in memory deep-sky objects of specific interest that are not currently in the AutoStar database. See page 30 for more information.

Landmarks stores the location of terrestrial points of interest in the permanent AutoStar database.

IMPORTANT NOTE: To use the Landmark function, the telescope must be located and aligned exactly as when the landmark was added to the database.

JSelect: To select a Landmark already in the database (see ADD below), choose the "Select" option and scroll through the list. Press ENTER to select a Landmark, then press GO TO and the telescope slews to the object.

JAdd: To add a Landmark, choose the "Add" option. Enter a name for the Landmark. Locate and center the Landmark in the eyepiece, then press ENTER.

Identify is an exciting feature for an observer who wants to scan the night sky and start exploring. After the telescope has been properly aligned, use the AutoStar Arrow keys to move about in the sky. Then follow this procedure:

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.
