Some of the major features of AutoStar are: { { { { Automatically move the telescope to any of the 30, 000 objects stored in the database or manually enter the astronomical coordinates of any celestial object. [. . . ] 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. 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. 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. 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. Find rise and set times for other dates by entering a new date into the "Setup: Date" menu. Moonrise and Moonset calculates the time that the Moon rises or sets on the current date. Find rise and set times for other dates by entering a new date into the "Setup: Date" menu. [. . . ] When the alarm goes off, return to the Satellite menu and press a Scroll key until the desired satellite is on the top line of the display. NOTE: If the scheduled appearance position of the satellite is obstructed (i. e. , by a building, tree, or hill), press ENTER and AutoStar starts to move the telescope along the expected satellite track. When the track clears the obstruction, press ENTER again to pause the telescope, then continue with this procedure. 6. 7. 8. 9. With about 20 seconds left on the countdown timer, start watching through the telescope viewfinder for the satellite to enter the field of view. 10. [. . . ]
