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.

Moonrise and Moonset calculates the time that the Moon rises or sets on the current date.

Moon Phases displays the date and time of the next New, 1st Quarter, Full and 3rd Quarter Moon.

Meteor Showers provides information on upcoming meteor showers, such as the Perseids, the Leonids, etc. Also lists the dates of the showers and when they reach maximum.

NOTE: Meteors are fast moving objects that cover large areas of the sky and are usually best observed with the naked eye.

Solar Eclipse lists upcoming solar eclipses, including the date and type (total, annular, or partial) 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 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.

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

2.8days 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. AudioStar 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 AudioStar functions. Access directly through the Glossary menu or through hypertext words embedded in AudioStar A hypertext word is any word in [brackets], usually found when using the AudioStar 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 AudioStar 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 AudioStar, 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. See OBSERVING SATELLITES, Page 45. 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,

LX80 specifications

The Meade LX80 is a versatile and innovative telescope designed to cater to both novice astronomers and experienced stargazers. Its combination of performance, ease of use, and advanced features makes it a popular choice among enthusiasts seeking to explore the cosmos.

One of the standout characteristics of the LX80 is its extensive GoTo mount system, which allows users to automatically locate and track celestial objects with remarkable precision. This feature is powered by a database containing over 30,000 astronomical objects, providing a broad range of targets for exploration. The telescope's integrated GPS ensures swift alignment with the night sky, simplifying setup and enhancing the observing experience.

The LX80 employs advanced technology with its heavy-duty dual-axis equatorial mount, providing stability and sturdiness. This design is particularly beneficial for astrophotography, as it minimizes vibrations and allows for longer exposure times without blurring. Additionally, the mount is compatible with various optical tubes, enabling users to customize their setup according to their specific interests, whether it’s planetary observation or deep-sky photography.

Another impressive feature of the Meade LX80 is its SmartDrive technology, which continually corrects any tracking errors, ensuring smooth and accurate movement across the night sky. This is especially helpful for capturing high-quality images of celestial bodies. The telescope can also be controlled via a smartphone or tablet using the optional Meade app, which further adds to its user-friendly design.

The LX80's optical performance is equally commendable. Many models come with a high-quality optical tube, offering superb light-gathering capabilities. The telescope's aperture, typically ranging from 6 to 10 inches, makes it well-suited for observing faint deep-sky objects like galaxies and nebulae, as well as brighter targets such as planets.

In terms of portability, the LX80 is designed to be compact, making it easier to transport to dark-sky locations. The telescope can be quickly set up and dismantled, accommodating astronomers who wish to observe in various settings.

Overall, the Meade LX80 stands out as a dynamic and feature-rich telescope. With its powerful GoTo capabilities, advanced tracking technology, and customizable optics, it offers a well-rounded observational experience. Whether you're peering through the eyepiece for the first time or capturing stunning images of the universe, the LX80 is equipped to meet your astronomical needs.
