Never use a Meade® Telescope to look at the Sun! [. . . ] Lunar Eclipse lists upcoming Lunar Eclipses, including the date and type (total, partial, penumbral) of eclipse. (Minimum) of Algol is the minimum brightness of the dramatic eclipsing binary star system, Algol. Every 2. 8 days during a 10-hour 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. 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. WARNING!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. Children should always have adult supervision while observing.

Display Options enables or disables Autostar's two initial displays. Sun Warning: Turns the "Sun Warning" message on or off. Getting Started: Turns the "Getting Started" message on or off. DS-2000 TIPS Observing Considerations · Try to pick an observing site away from street and house lights, and car headlights. [. . . ] Because of their vast distances from our solar system, all stars appear as pinpoints of light, irrespective of the size of the telescope used. Nebulae are vast interstellar clouds of gas and dust where stars are formed. Most impressive of these is the Great Nebula in Orion (M42), a diffuse nebula that appears as a faint wispy gray cloud. Open Clusters are loose groupings of young stars, all recently formed from the same diffuse nebula. [. . . ]
