Important Note: No matter how many levels into AudioStar are traveled, each press of the MODE key moves up a level, until the top level, “Select Item”, is reached. Once in the Select Item level, press MODE to return to the topmost level, “Select Item: Object”.

AudioStar Navigation Exercise

To demonstrate how the AudioStar menu structure works, the following exercise calculates Sunset time so an evening observing session can be planned.

To Calculate Sunset time:

1.Press the MODE key several times, until “Select Item: Object” is displayed.

AudioStar Operation

Fig. 40: The AudioStar Universe: The six primary categories listed in the Select Item menu of AudioStar.

It is important to understand that menu selections are set in a loop (Fig. 40). This means that pressing the Scroll Down key (Page 33, Fig. 39, 7) cycles down through all the available options within a given category, then returns to the first option. The Scroll Up key (Page 33, Fig. 39, 7) cycles up through the options in the opposite order. Note that this capability is a quick way to get to an option that is near the bottom of the list. The following example demonstrates this capability.

Example:

To navigate to the “Select Item: Setup” menu option

when the “Select Item: Object” menu is displayed:

1.Press the Scroll Down key four times or the Scroll Up key once.

The screen in Fig. 41 displays two lines of information. The top line shows the current menu level. The second line displays an option which may be selected within that menu level. Some options are choices that select the next menu level down. The Scroll keys move up and down within the list of available options, showing one option at a time.

When the desired option is displayed on the second line, press the ENTER key to choose that option and move down one menu level.

Press the MODE key to leave a level; e.g., the wrong menu option is chosen.

2.Press the Scroll Down key once to display the “Event” option in the “Select Item” menu.

3.Press the ENTER key to choose the “Event” option and move down a level. “Event: Sunrise” is displayed.

4.Press the Scroll Down key once to display the “Sunset” option in the Event menu.

5.Press the ENTER key to choose the “Sunset” option and move down another level.

6.AudioStar calculates the Sunset time based on the current date, time, and location. AudioStar then displays the results of the calculation.

7.Press MODE once to start moving back up through the AudioStar levels. The first level up is the Event menu.

8.Press MODE again to move up another level. This is the top level, “Select Item”.

9.Press MODE again to return to the starting point of “Select Item: Object”.

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.
