PeriodicErrorCorrection(PEC)Training (Polar Alignment and RA Drive Only)

If you wish to improve the tracking performance on your telescope, first, perform the train the drive procedure (see page 57). Then use the Periodic Error Correction (PEC)/Train menu option to remove the slight perturbations from center that occur due to the mechanical nature of a telescope. To perform this procedure, you need to use a high-power reticle, such as the 9mm reticle (see OPTIONAL ACCESSORIES, page 52).

Important Note: In order for the Smart Drive training to operate and be updated properly, you must “park” the telescope (see PARK SCOPE, page 41) when finished with your observing session.

PEC Train Menu Option

To perform the procedure on the RA axis, pick a bright star in the South that has minimal movement and is about 30° above the horizon (Note: If in the Southern hemisphere, pick a star in the North that is about 30° above the horizon).

Important Note: The Train option overwrites any previous PEC data.

1.Select “PEC Train” from the Smart Drive menu (in the “Setup: Telescope” menu) and press ENTER.

2.Look through the reticle. Use the Arrow keys to keep the star centered in the reticle cross-hairs. AudioStar displays a count of the 150 positions of the worm gear. When the count reaches 150, one cycle is complete. A full cycle takes about 9.5 minutes.

3.Press MODE to exit.

PEC Update Menu Option

PEC Update does not overwrite the data, but updates the training using information gathered from both the last and the current training sessions. Press the MODE key to exit from this option. If you wish to further refine your training, select this menu again and repeat the procedure.

PEC Erase Menu Option

Select this option to erase all PEC training data.

PEC On and Off Menu Options

Select “On” when you want the telescope to use the training information. Select “Off” when you do not want for the telescope to use the training information.

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.
