GETTING STARTED

Getting the telescope ready for first observations requires only a few minutes. When first opening the packing box, note carefully the following parts:

LX90 Telescope with fork mount system and attached SmartFinder

AutoStar handbox and interface coil cord

Eyepiece holder and 1.25” diagonal prism

8 x 50 Viewfinder

Super Plössl 26mm eyepiece

Variable height tripod and mounting base

Set of hex wrenches and a plastic bag containing a “C” clip and a washer

How to Attach the Tripod to the Telescope Assembly

The telescope’s fork mount attaches directly to the field tripod. The telescope in this way is mounted in an “Altazimuth” (“Altitude-Azimuth,” or “vertical-horizontal”) format. The telescope in this configuration moves along vertical and horizontal axes, corresponding respectively to the Declination (vertical) and Right Ascension (horizontal) axes in an astronomical observing mode.

The field tripod also can be used in conjunction with the optional equatorial wedge (see EQUATORIAL WEDGE, page 52) for long exposure astrophotography. The equatorial wedge per- mits alignment of the telescope’s Polar Axis with the Celestial Pole (or North Star).

1.After removing the field tripod from its shipping carton, stand the tripod vertically, with the tripod feet down and with the tripod still fully collapsed (see Fig. 3). Grasp two of the tri- pod legs and, with the full weight of the tripod on the third leg, gently pull the legs apart to a fully open position.

2.Thread in the 6 lock-knobs (2 on each tripod leg) near the foot of each tripod leg (Fig. 3). These lock-knobs are used to fix the height of the inner, extendible tripod leg sections.

NOTE: Tightening to a firm-feel is sufficient; over-tightening may result in stripping of the knob threads or damage to the tripod legs and results in no additional strength.

3.The spreader bar (4, Fig. 3) has been removed for shipment. To install, first remove the threaded rod (2, Fig.3) from the tripod head (1, Fig. 3); a small piece of plastic holds the threaded rod in place. Remove the small plastic bag that is stapled to the threaded rod. This bag contains the “C” clip retainer and an extra clip.

4.Slide the washer followed by the spreader bar onto the threaded rod (note the correct ori- entation as shown in Fig. 4) and position the threaded rod back through the tripod head. Place the clip retainer ( a “C” clip) into the slot in the threaded rod. This clip holds the thread- ed rod in place. See Fig. 3.

5.Position the spreader bar so that the 3 arms of the spreader bar line up with the 3 tripod legs.

LX90GPS specifications

The Meade LX90GPS is a premium telescope that offers both amateur and seasoned astronomers a powerful and user-friendly platform for exploring the night sky. This telescope blends advanced technology with robust design, making it one of the preferred choices for stargazers around the globe.

One of the standout features of the LX90GPS is its Advanced Coma-Free (ACF) optics. This design minimizes spherical aberration and eliminates off-axis coma, ensuring sharp, high-contrast images across the entire field of view. Coupled with a large aperture of 8, 10, or 12 inches, users can enjoy stunning views of celestial objects including planets, galaxies, and nebulae.

The telescope is equipped with a fully automated GoTo system that simplifies the hunting of celestial objects. The built-in GPS makes for effortless location setting, locking onto satellites and positioning the telescope accurately. Once set up, users can access a database containing over 30,000 celestial objects, allowing for easy navigation and exploration.

In addition to its exceptional optics and GoTo capabilities, the LX90GPS features Smart Mount technology. This innovative system incorporates adjustments based on real-time sky data, ensuring that the telescope remains aligned with celestial bodies as they move across the night sky. The LX90GPS also includes a unique Auto-Alignment feature, where a simple two-star alignment procedure helps calibrate the telescope quickly and easily.

The design of the LX90GPS is user-centric, combining functionality with comfort. The telescope comes with an easy-to-operate control panel and a large, multi-line LCD screen that displays critical information. Users can easily manage various functions and settings without fumbling through complex menus.

Additional features include the option for removable optical tubes, allowing for easy upgrades or repairs. The telescope is compatible with a variety of Meade accessories, including focal reducers and filter sets, enhancing its versatility for different observing conditions.

In conclusion, the Meade LX90GPS stands out for its remarkable optics, user-friendly technology, and impressive range of features. Whether you’re gazing at the Moon, tracking planets, or delving into deep-sky observations, the LX90GPS provides a fulfilling astronomical experience that inspires exploration and delight in the universe.
