Number Keys: Input digits 0 - 9 and changes the slew speeds (see Slew Speeds, see below). The “0” key also turns on and off the red utility light on the top of the handbox.

Note: While the audio descriptions are playing, the 7 and 9 keys adjust the speaker volume. Press 7 to decrease the volume. Press 9 to increase the volume

Slew Speeds

LX80 has nine slew speeds that are directly proportional to the sidereal rate (the rate at which stars appear to drift across the sky) and have been calculated to accomplish specific functions. Pressing a Number key changes the slew speed, which is shown for about two seconds on AudioStar’s display.

To change the speed, press the appropriate key shown below.

Nine available speeds are:

Number Key 1 =

 

 

Guide (0.25 arc-min/sec

 

 

 

 

or 0.004°/sec)

Number Key 2 =

2x

=

2x sidereal (0.5 arc-min/sec

 

 

 

 

or 0.008°/sec)

Number Key 3 =

8x

=

8x sidereal (2 arc-min/sec or

 

 

 

 

0.033°/sec)

Number Key 4 =

16x =

16x sidereal (4 arc-min/sec

 

 

 

 

or 0.067°/sec)

Number Key 5 =

64x =

64x sidereal (16 arc-min

 

 

 

 

sec or 0.27°/sec)

Number Key 6

=

128x =

30arc-min/sec or 0.5°/sec

Number Key 7

=

1.5° =

90arc-min/sec or 1.5°/sec

Number Key 8

=

3° =

180arc-min/sec or 3°/sec

Number Key 9

=

Max =

270arc-min/sec or 4.5°/sec

Speeds 1, 2 or 3: Best used for fine centering of an object in the field of view of a higher power eyepiece, such as a 12mm or a 9mm eyepiece.

Speeds 4, 5 or 6: Enables centering an object in the field of a low-to-moderate power eyepiece, such as the standard 26mm.

Speeds 7 or 8: Best used for rough centering of an object in the viewfinder.

Speed 9: Moves the telescope quickly from one point in the sky to another.

Scroll Keys: Accesses options within a selected menu. The menu is displayed on the first line of the screen. Options within the menu are displayed, one at a time, on the second line. Press the Scroll keys to move through the options. Press and hold a Scroll key to move quickly through the options.

The Scroll keys also scroll through the letters of the alphabet and numerical digits.

Note: The Scroll Down key and the Down Arrow key move forward through the alphabet and digits (A to Z, 0 to 9). The Scroll Up key and the Up Arrow key move backward (Z to A, 9 to 0). Common symbols are also available in the list.

?Key: Accesses the “Help” file. “Help” provides on-screen information on how to accomplish whatever task is currently active.

Hold down the ? key and then follow the prompts on the display to access details of AudioStar functions in the Help feature. The Help system is essentially an on-screen instruction manual.

If you have a question about an AudioStar operation, e.g., INITIALIZATION, ALIGNMENT, etc., hold down the ? key and follow the directions that scroll on the second line of the LCD screen. When a word appears in [brackets], press ENTER to access the AudioStar Glossary. A definition or more detailed information is displayed. Press MODE to return to the scrolling AudioStar Help display.

When satisfied with the Help provided, press MODE to return to the original screen and continue with the chosen procedure.

Coil Cord Port: Plug one end of the AudioStar coil cord into this port (Page 33, Fig 39, 9) located at the bottom of the AudioStar handbox.

Coil Cord: Plug one end of the AudioStar coil cord into the HBX port (Page 10, Fig 3, D) of the computer control panel of the telescope and the other end into the coil cord port.

Serial Port: Plug a serial accessory (#505) cable into AudioStar for updating functions such as “Download” or “Clone”. See Page 43 for

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.
