Solar Eclipse lists upcoming Solar Eclipses, including the date and type (total, annular, or par- tial) of eclipse, and the location and time of the first and last contacts of the Moon's shadow. Use the Scroll Up and Down keys to display the available data. Remember, never use a tele- scope to look at the Sun! See “WARNING!” on page 23.

Lunar Eclipse lists upcoming Lunar Eclipses, including the date and type (total, partial, penum- bral) of eclipse. Use the Scroll Up and Down keys to display the available data.

Min. (Minimum) of Algol is the minimum brightness of the dramatic eclipsing binary star sys- tem, Algol. It is relatively close at a distance of 100 light years. 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. 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. Press ENTER on the desired letter. 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 count- down 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. See OBSERVING SATELLITES, page 34. To use the Timer, press ENTER, then choose “Set” or “Start/Stop."

■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. When the timer runs out, four beeps sound and the timer is deactivated.

Alarm selects a time for an alarm signal as a reminder. To use the Alarm, press ENTER, then choose "Set" or "Start/Stop."

■Set: Enter the time of day for the alarm to sound, in hours, minutes, and seconds, then press

ENTER.

■Start/Stop: Activates the alarm set previously. Use the Scroll keys to toggle between ON and OFF. When ON is displayed, press ENTER to activate the alarm. When the alarm time arrives, Autostar beeps. Press ENTER to deactivate the alarm.

Eyepiece Calc calculates information about an eyepiece for the specific telescope to which Autostar is connected.

■Field of View: Scroll through a list of available eyepieces. When an eyepiece is selected, the field of view is calculated.

■Magnification: Scroll through a list of available eyepieces. When an eyepiece is selected, the magnification is calculated.

■Suggest: Autostar calculates and suggests the best eyepiece for viewing, based on the telescope and the object being viewed.

DS-114AT specifications

The Meade DS-114AT is a popular entry-level telescope that combines user-friendliness with impressive optical performance, making it an excellent choice for budding astronomers and hobbyists. With its robust design and advanced features, the DS-114AT offers a gateway to the wonders of the cosmos, whether you’re observing the craters of the Moon, the rings of Saturn, or distant star clusters.

One of the standout features of the Meade DS-114AT is its 114 mm (4.5-inch) diameter aperture. This sizable opening allows for greater light-gathering capability, resulting in brighter images and improved visibility of celestial objects. The telescope is equipped with a 900 mm focal length, providing a good balance that allows for both wide-field viewing and detailed observations of planets and lunar features.

The DS-114AT utilizes high-quality optics featuring a parabolic mirror design. This design minimizes spherical aberration, ensuring crisp images of astronomical targets. The telescope is also equipped with a fully coated optical system that enhances light transmission and reduces glare, providing clearer images compared to other telescopes in its class.

Portability is another significant advantage of the Meade DS-114AT. Its lightweight and compact design allows for easy transportation, making it ideal for backyard stargazing or trips to darker skies. The telescope comes with a sturdy yet lightweight altazimuth mount that facilitates smooth movement, allowing users to easily locate and track celestial objects.

The Meade DS-114AT also features a user-friendly electronic control system, including an automated GoTo functionality that aids in navigating the night sky. With a simple push of a button, users can precisely locate thousands of celestial objects, making the telescope accessible for beginners who may not yet be familiar with star maps and constellations.

Additionally, the telescope includes two eyepieces, a 9 mm and a 25 mm, allowing for various magnifications to suit different viewing preferences. The optical finder scope aids in quick alignment, ensuring a hassle-free observing experience.

In summary, the Meade DS-114AT stands out as a versatile, user-friendly telescope that provides excellent optical performance and advanced features. Its combination of a sizable aperture, high-quality optics, portability, and automated features make it an ideal choice for those looking to explore the universe, whether for casual observations or more serious astronomical pursuits. With this telescope, the night sky is truly within reach.
