Slew speed does not change when you change slew speeds or the telescope moves slowly even though the fast slew speed is chosen:

•The battery power may be low. Replace all batteries with fresh, new units.

Telescope does not track a celestial object:

•Make sure that the telescope is correctly aligned. See Easy (Two-Star) Align, Page 26, for more information.

Images through the eyepiece appear unfocused or distorted:

•The magnification may be too high for the viewing conditions. Back off to a lower power eyepiece (see “Eyepiece Calc”, Page 41).

•If inside a warm house or building, move outside. Interior air conditions may distort terrestrial or celestial images, making it difficult, if not impossible, to obtain a sharp focus. For optimal viewing, use the telescope outside in the open air instead of observing through an open or closed window or screen.

•If viewing a land object on a warm day, heat waves will distort the image (see Terrestrial Observing, Page 36).

•For clear viewing of objects, turn the focus knob (Page 8, Fig. 1, 11) slowly since the “in-focus” point of a telescope is precise. Turning the focus knob too quickly may cause the focus point to pass without notice.

•The optics within the telescope need time to adjust to the outside ambient temperature to provide the sharpest image. To cool down the optics, set the telescope outside for 10 to 15 minutes before observing begins.

Telescope moves off a terrestrial object while observing:

•Verify that the DEC and RA locks are tight (see LX80 KEY FEATURES, Page 8, Fig 1, 29 and 30).

Telescope pauses when changing slew direction:

•This pause is normal.

A terrestrial object appears reversed left-for-right:

•When using a Schmidt Cassegrain optical tube

an eyepiece in the standard 90° observing position reverses an object left-for-right: To view a correctly oriented image requires the optional #932 Erecting Prism.

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.
