How to Assemble Your Telescope

The giftboxes contain the optical tube assembly and the tripod with the equatorial mount. The accessories are located within compartments custom-cut into the styro- foam block inserts.

1.Remove the components from the giftboxes: Remove and identify the tele- scope’s equipment. Refer to Figures 1a through 1f for images of the parts and the overall assembly of your telescope. When removing the tripod from the gift- box, hold the assembly parallel (horizontal) to the ground or the inner tripod leg extensions will slide out as they are not locked in place.

2.Adjust the tripod legs. Spread the tripod legs as far as they will open. See Fig. 3.

3.Attach the spreader bar to the tripod with shaft: Thread the tension knob onto the shaft (see Fig. 4). Place the spreader bar over the T-handle shaft. Slide the bushing, the wide open side facing downward, onto the shaft as far as it will go (Fig. 5a). Then slide the shaft up through the tripod mounting base (37, Fig. 1c). Above the mount, snap the e-clip into the second, narrower precut slot (see Fig. 5a) of the shaft (Fig. 5b).

4.Attach mount to tripod base: Place the mount over the tripod mounting base (37, Fig. 1c) and onto the shaft, with the protrusion on top of the tripod's base positioned between the fine azimuth control knobs (27, Fig. 1d). See Fig. 5c. If necessary, back off the azimuth control knobs wide enough for protrusion to fit between them.

Tighten the T-handle to a firm feel. This attachment keeps the tripod and the tel- escope mount securely in place. Then line up the spreader bar braces so that they are each touching one of the tripods legs. Tighten the tension knob (39, Fig. 1c) to a firm feel. When you wish to collapse the tripod, loosen the tension knob and move the braces off the legs. You do not need to remove the T-handle/shaft.

5.Attach the counterweight(s) to the counterweight shaft: Place the counter- weight shaft base (20, Fig. 1d) over the threaded end of the shaft (22, Fig. 1d). Thread the shaft and base assembly into the hole beneath the Dec. setting circle as depicted in Fig. 6.

Look through the hole in the counterweight and note the pin blocking the hole. Tilt the counterweight slightly and the pin moves out of position, clearing the hole. If the pin does not move, unscrew the counterweight lock knob slightly until the pin moves.

Unscrew the safety cap (23, Fig. 1d) from the shaft. Holding the counterweight (21, Fig. 1d) firmly in one hand, slip the counterweight to approximately the mid- point of the counterweight shaft (22, Fig. 1d). Tighten the counterweight lock knob to a firm feel. Replace the safety cap.

LXD 75 specifications

The Meade LXD 75 is an advanced telescope mount designed for both amateur and professional astronomers looking to explore the wonders of the night sky. Known for its precision and ease of use, the LXD 75 offers several features and technologies that make it a standout choice for astrophotography and visual observation alike.

At the heart of the Meade LXD 75 is its robust equatorial mount, which provides stable tracking of celestial objects. This mount is both lightweight and durable, allowing for easy transport to observing sites. The equatorial design is especially beneficial for astrophotography, as it compensates for the Earth's rotation, enabling longer exposure times without the trailing effects commonly associated with less sophisticated mounts.

One of the most notable features of the LXD 75 is its dual-axis tracking system. This system allows users to electronically control the telescope's movements along both the right ascension and declination axes. The built-in Data Sky control panel is user-friendly, offering intuitive access to a wealth of astronomical data, including over 30,000 celestial objects. This makes locating and tracking objects in the sky simpler and more efficient.

The LXD 75 also supports a variety of telescope configurations, accommodating optical tubes up to 10 inches in diameter. This versatility makes it suitable for a range of viewing preferences, from planetary observations to deep-sky astrophotography. The mount's heavy-duty construction ensures it can handle the weight of larger telescopes while maintaining stability.

In terms of technology, the Meade LXD 75 is equipped with AutoStar computer technology. This innovative feature enables automatic location and tracking of celestial bodies using a simple pointing and clicking interface. Users can also create custom observing lists, making it easier to plan and execute dedicated viewing sessions.

Additionally, the LXD 75 boasts robust connectivity options, including the ability to integrate with a wide range of imaging software and accessories, making it a great choice for those interested in advanced astrophotography techniques. The mount's compatibility with Meade's own range of cameras and filters further enhances its potential for capturing stunning images of the universe.

In conclusion, the Meade LXD 75 is a well-rounded telescope mount that combines advanced technology with user-friendly features. Its equatorial design, dual-axis tracking, and AutoStar system make it an excellent choice for both novice and experienced astronomers. Whether for visual observation or astrophotography, the LXD 75 offers the performance and versatility to enhance any stargazing experience.
