[. . . ] Instruction Manual DSX Series Altazimuth Maksutov-Cassegrain Telescopes Meade Instruments Corporation CONTENTS WARNING! Never use a Meade® DSXTM 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 the telescope or its viewfinder at or near the Sun. [. . . ] Use the Scroll Up and Down keys to display the available data. Remember, never use a telescope to look at the Sun!Lunar Eclipse lists upcoming Lunar Eclipses, including the date and type (total, partial, penumbral) of eclipse. Use the Scroll Up and Down keys to display the available data. 24 Min. (Minimum) of Algol is the minimum brightness of the dramatic eclipsing binary star system, Algol. It is relatively close at a distance of 100 light years. Every 2. 8 days during a 10hour period, Algol undergoes a major change in apparent magnitude as one of the two stars passes behind the other. The combined magnitude of the two stars thus dips from +2. 1 to a minimum of +3. 4 halfway through the eclipse as the second star is hidden. Autostar calculates minimum magnitude time at mid-eclipse. Autumn and Vernal Equinox calculates the time and date of the fall or spring equinox of the current year. Winter and Summer Solstice calculates the time and date of the winter or summer solstice of the current year. Glossary Menu The Glossary menu provides an alphabetical listing of definitions and descriptions for common astronomical terms and Autostar functions. Access directly through the Glossary menu or through hypertext words embedded in Autostar. A hypertext word is any word in [brackets], usually found when using the Autostar Help function or when reading a scrolling message such as a description of a planet or star. Press ENTER whenever a hypertext word is on screen and Autostar goes to the glossary entry for that word. To access directly from the Glossary menu, use the Scroll keys to scroll through the alphabet. Scroll to the desired entry and then press ENTER to read the description. Utilities Menu The Utilities menu provides access to several extra features within Autostar, including a countdown timer and an alarm. The Utilities functions include: Timer selects a countdown timer. This feature is useful for functions such as astrophotography and tracking satellites. To use the Timer, press ENTER, then choose "Set" or "Start/Stop. " s s Set: Enter the time to be counted down, in hours, minutes, and seconds, then press ENTER. Start/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. [. . . ] Open Clusters are loose groupings of young stars, all recently formed from the same diffuse nebula. The Pleiades is an open cluster 410 light years away (Fig. Constellations are large, imaginary patterns of stars believed by ancient civilizations to be the celestial equivalent of objects, animals, people, or gods. These patterns are too large to be seen through a telescope. [. . . ]
