LXD75-Series:Your Personal Window to the Universe

The Meade LXD75-Series models are versatile, high-resolution telescopes. Supplied with either an Electronic Controller or an Autostar handbox, the LXD75-Series models offer unmatched mechanical and electronic performance.

The LXD75-Series telescopes reveal nature in an ever-expanding level of detail. Observe the feather structure of an eagle from 50 yards or study the rings of the plan- et Saturn from a distance of 800 million miles. Focus beyond the Solar System and observe majestic nebulae, ancient star clusters, and remote galaxies. Meade LXD75- Series telescopes are instruments fully capable of growing with your interest and can meet the requirements of the most demanding advanced observer.

Refer to Figures 1a through 1e for the following features:

B Eyepiece Thumbscrew: Tightens the eyepiece (see d) in place. Tighten to a firm feel only.

C Eyepiece Holder: Holds eyepiece in place. Holders supplied for both 1.25" and 2" eyepieces.

Diagonal (not shown, achromatic refractor and Schmidt-Cassegrain models

only): Provides a more comfortable right-angle viewing position. Slide the diagonal directly into the eyepiece holder (see c) and tighten the thumbscrew on the eye- piece holder to a firm feel only. See page 13 for a photo and more information.

D Eyepiece: Place the supplied Super Plössl 26mm eyepiece into the eyepiece holder or the diagonal and tighten in place with the eyepiece thumbscrew (see b). The eyepiece magnifies the image collected in the optical tube.

D8 x 50mm (all models, except N-6EC Newtonian) or 6 x 30mm (N-6EC Newtonian only) Viewfinder: A low-power,wide-field sighting scope with

crosshairs that enables easy centering of objects in the telescope eyepiece (see d).

EViewfinder Collimation Screws (6): Use these screws to adjust the alignment of the viewfinder.

FViewfinder Front Cell and Locking Ring: Adjust the front cell to focus the viewfinder. See step 3, page 14 for more details. The viewfinder is supplied with a small dust cover placed over the front cell.

GViewfinder Bracket: Holds the viewfinder in place.

HFocus Knobs: Moves the telescope’s focuser drawtube in a finely-controlled motion to achieve precise image focus. The LXD75-Seriestelescopes can be focused on objects from a distance of about 75 ft. to infinity. Rotate the focus knobs to focus on objects.

ICorrector/Dust Cover: Place the dust cover (not visible in photo) over the cor- rector when storing the telescope.

Note: The dust cover should be replaced after each observing session and the power turned off to the telescope. Allow time for any dew that might have collected during the observing session to evaporate prior to replacing the dust cover.

1) Optical Tube: The main optical component that gathers the light from distant objects and brings this light to a focus for examination through the eyepiece.

1! Cradle Assembly: Attaches to mount base. See 1# and 1$.

1@ Autostar™: See pages 9 and 10 for a description of features.

1# Cradle Ring Lock Knobs (2) and Washers (2): Slide washers onto lock knobs before inserting. Tighten to a firm feel to secure the optical tube in place.

1$ Cradle Rings (2): Part of the cradle assembly (see 1!); hold the optical tube firm- ly in place.

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.
