finished observing to protect the eyepiece assembly. Back off the eyepiece thumbscrews (1, Fig. 1b) and slide the diagonal into the holder and tighten the thumbscrews to a firm feel only. Insert the supplied SP 26mm eyepiece (3, Fig. 1b) into the the diagonal. Tighten the diagonal's thumbscrews to a firm feel to secure the eyepiece.

Note: Two eyepiece holders are included with your telescope—for both 1.25" and 2" eyepieces. To change eyepiece holders, unscrew the attached holder from the focuser and thread on the other holder.

11.Adjust the height of the tripod: Adjust the height of the tripod by loosening the tripod lock knobs (Fig. 11). Extend the sliding inner section of each tripod leg to the desired length; then tighten each knob. Adjust the tripod to a height that is comfortable for viewing.

12.Install Batteries: Insert eight (user-supplied) D-size batteries into the battery holder, oriented as shown in the diagram on the battery slots of the holder. Plug the battery pack into the 12v DC connector (B, Fig. 1e) on the computer control panel. See Fig. 12.

Caution: Use care to install batteries as indicated by the battery com- partment. Follow battery manufacturer's precautions. Do not install bat- teries backwards or mix new and used batteries. Do not mix battery types. If these precautions are not followed, batteries may explode, catch fire, or

13.Remove Plastic Strip from Reticle LED: The polar alignment reticle LED (30, Fig. 1d) contains two watch batteries. The reticle's LED is shipped with a plastic strip between the two batteries to protect battery life. Unthread both the cap (F) and the threaded lid (E). Remove the plastic strip before using. Refer to the reti- cle assembly in Fig. 13b and note the orientation of the batteries. Place the bat- teries (C) into the battery holder (D) before inserting into the reticle container (A).

Note: Remember to turn off the LED when you are not using the reticle.

14.Plug in Autostar or EC Handbox: Plug the Autostar or EC handbox cable into the HBX port (A, Fig. 1e).

Balancing the Telescope

In order for the telescope to be stable on the tripod and also for it to move smoothly, it must be balanced. To balance the telescope, unlock the Right Ascension or R.A. lock (33, Fig. 1d). When this axis is unlocked, the telescope pivots on the R.A. axis. Later in the procedure, you will also unlock the Declination or Dec. lock (17, Fig. 1d). When unlocked, the telescope pivots on the Dec. axis. Most of the motion of the tel- escope takes place by moving about these two axes, separately or simultaneously. Try to become familiar with these locks and observe how the telescope moves on each axis. To obtain a fine balance of the telescope, follow the method below:

1.Firmly hold the optical tube secure so that it cannot accidentally swing freely. Loosen the R.A. lock (33, Fig. 1d). The optical tube now moves freely about the 13 R.A. axis. Rotate the telescope so that the counterweight shaft (22, Fig. 1d) is parallel (horizontal) to the ground.

LXD75 specifications

The Meade LXD75 series represents a remarkable range of telescopes designed for both amateur astronomers and advanced users seeking high-quality performance at an affordable price. Known for its robust construction and innovative technology, the LXD75 aims to provide a user-friendly experience while catering to the demands of stargazers looking for sophistication in their equipment.

One of the main features of the LXD75 is its advanced German equatorial mount, which provides exceptional stability and tracking accuracy. This mount is equipped with dual-axis servo motors facilitating smooth movements, making it easy to locate and follow celestial objects. The LXD75 also includes a built-in autostar system featuring a database of over 30,000 celestial objects, allowing users to effortlessly navigate the night sky with a push of a button.

The LXD75 series includes several models, each with different optical configurations to suit the preferences of various users. The telescopes come with either an achromatic refractor or Schmidt-Cassegrain optical design, providing clear and bright images. The Schmidt-Cassegrain models offer a compact design with a fast focal ratio, making them excellent for both astrophotography and visual observation.

In terms of build, the Meade LXD75 features high-quality optics with multi-coated lenses, reducing glare and enhancing light transmission. This results in sharper and brighter images, making it easier to observe delicate details on planets, the moon, and deep-sky objects. The telescope tubes are crafted from durable materials, ensuring longevity and resilience against the elements.

Another characteristic worth noting is the ease of setup and operation. The LXD75 mount comes equipped with adjustable legs and can be easily assembled, requiring minimal tools. The intuitive control system also features a user-friendly interface, allowing both novices and experienced astronomers to operate the telescope with confidence.

For astrophotography enthusiasts, the LXD75 provides excellent support, with a wide range of accessories available to enhance imaging capabilities. The mount can accommodate various cameras, providing flexibility for capturing stunning astronomical photographs.

In summary, the Meade LXD75 series delivers a robust combination of features, technologies, and characteristics designed to meet the needs of both amateur and advanced astronomers. With its reliable mount, quality optics, and ease of use, the LXD75 ensures that stargazers can enjoy the wonders of the universe with clarity and precision.
