[. . . ] When this menu option is chosen and a constellation name appears on the first line of the screen, press GO TO once to change the second line to the name of the brightest star in the constellation. Press GO TO a second time to slew the telescope to that star. Use the Scroll keys to cycle through the list of stars in the constellation, from brightest to dimmest. Deep Sky is a database of objects outside our Solar System such as nebulae, 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 "Appendix B" 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. { Select: 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. Add: To add a Landmark, choose the "Add" option. 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: IMPORTANT NOTE: Only use the Arrow keys to move the telescope during the Identify procedure. Do not loosen the telescope locks or move the base or alignment is lost. When a desired object is visible in the eyepiece, keep pressing MODE until the "Select Item: Object" menu is displayed. Scroll through the Object menu options until the "Object: Identify" screen appears. AutoStar searches the database for the identity of the object being observed. If the telescope is not directly on an AutoStar database object, the nearest database object is located and displayed on the screen. Press GO TO and the telescope slews to that object. 12 Event Menu The Event menu provides access to dates and times of astronomical events. The Event database includes: Sunrise and Sunset calculates the time that the Sun rises or sets on the current date. [. . . ] Use the AutoStar Arrow keys to center the object in the viewfinder, then look through the eyepiece to view the object. Satellite orbits change and new satellites (including the Space Shuttle) are launched. Visit the Meade website (www. meade. com) approximately once a month to get updated information and instructions on how to download this data to AutoStar. If orbital parameters are more than one month old, the satellite pass may not happen at the time predicted by AutoStar. [. . . ]
