Instruction Manual LXD™ 75 -Series Telescopes MEADE.
CONTENTS WARNING! Never use a Meade® LXD75™-Series Telescope to look at the Sun! Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope or its viewfinder at or near the Sun. Do not look through the telescope or its viewfinder as it is moving. Children should always have adult supervision while observing.

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. Caution: Using products other than standard Meade accessories may cause damage to the telescope’s internal electronics and may void the Meade warranty. The LXD75-Series telescopes reveal nature in an ever-expanding level of detail.
Caution When loosening the Dec. lock, be sure to support the optical tube (18, Fig. 1a). The weight of the tube could cause the tube to swing suddenly. 1% Viewfinder Bracket Screws: Tighten to a firm feel to hold viewfinder securely in place (see E and h). See page 12 for more information. 1^ Focus Lock Knob: Designed to prevent the focuser drawtube from moving when a heavy accessory, such as a camera, is attached to the focuser assembly.

Thumbscrew 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).
3. Collimation Screws Viewfinder Eyepiece Viewfinder Bracket Achromatic refractor, Schmidt-Newtonian models and Newtonian models: Again, hold the optical tube so that it cannot accidentally swing freely. Lock the R.A. lock (33, Fig. 1d), and unlock the Dec. lock (17, Fig. 1d). The telescope now is able to move freely about the Dec. axis. Loosen the cradle ring lock knobs (13, Fig. 1a) so that the main tube slides easily back and forth in the cradle rings.
Note: Seeing conditions vary widely from night-tonight and site-to-site. Turbulence in the air, even on an apparently clear night, can distort images. If an image appears fuzzy and ill-defined, back off to a lower power eyepiece for a more well-resolved image (see Fig. 15a and 15b below). Note: For a list of magnification ratings of the eyepieces available for the LXD75-Series telescopes, see OPTIONAL ACCESSORIES, page 37.
supplied with your telescope. When the object is centered and focused in the eyepiece, switch to a higher power eyepiece to enlarge the image as much as practical for prevailing viewing conditions. For information about other eyepieces available for your telescope, see OPTIONAL ACCESSORIES, page 37. W Once centered, an object can be focused by turning one of the knobs of the focusing mechanism (8, Fig. 1b).
Note: If you wish to perform a more precise polar alignment for the purposes of astrophotography, see "Appendix B," page 52. Speeds 1, 2, or 3: Best used for fine centering of an object in the field of view of a higher power eyepiece, such as a 12mm or a 9mm eyepiece. Speeds 4, 5, or 6: Enables centering an object in the field of a low-to-moderate power eyepiece, such as the standard Super Plössl 26mm. Speeds 7 or 8: Best used for rough centering of an object in the viewfinder.
Observe a Star using the Automatic Tracking Feature Tip: You can change the telescope's slew rate while centering an object in the eyepiece. See SLEW SPEEDS, page 16 for more information. In this example, Autostar's Arrow keys are used to find a star, and then Autostar's tracking capability automatically keeps the star centered in your telescope's eyepiece. EC handbox users, see APPENDIX D, page 58, for information about tracking with the EC handbox. 1.
Moving Through Autostar’s Menus (Autostar Models Only) Autostar's menus are organized for quick and easy navigation.

MENUS Object Menu Almost all observing with Autostar is performed using the Object menu category. (Note: Exceptions include Guided Tour and Landmark Survey.) See GO TO SATURN, page 21, for an example of observing using the Object menu. Also see USING THE GUIDED TOUR, page 22. Autostar contains many libraries of viewable objects, such as stars, planets, comets, nebulae and so forth.
Browse allows you to search the library for objects with certain parameters, much like a search engine. "Edit Parameters" lets you set various parameters for the search, such as: Object Type, Minimum Elevation, Largest, etc. Once you have set the parameters of the search, select "Start Search" and press ENTER. Autostar will display the results of the search. Event Menu The Event menu provides access to dates and times of astronomical events.
W Set: Enter the time to be counted down, in hours, minutes, and seconds, then press ENTER. W Start/Stop: Activates the timer set previously. Use the Scroll keys to toggle between ON and OFF. When ON is displayed, press ENTER to activate the timer. When the timer runs out, four beeps sound and the timer is deactivated. Alarm selects a time for an alarm signal as a reminder. To use the Alarm, press ENTER, then choose "Set" or "Start/Stop.
Want to learn more about using the Date menu? See the LXD75 TIPS box, page 24. Then check the "Select Item: Event" menu for the Sunset time on that date. See EVENT MENU, page 27. Time changes the time entered into Autostar. Setting the correct time is critical for Autostar to properly calculate locations and events. Time may be set to 24-hour mode (military time) by selecting the "blank" option (i.e., no option is displayed) which follows the "AM" and "PM" options.
Lunar: Choose this option to properly track the Moon over long observing sessions. c. Custom: Allows entry of user-defined tracking rates. Reverse L/R: Reverses the functions of the Left and Right Arrow keys (i.e., the Right key moves the telescope to the left). b. W Tip: The Reverse L/R and U/D functions are useful if you are observing in the Southern hemisphere. W Reverse U/D: Reverses the functions of the Up and Down Arrow keys (i.e., the Up key moves the telescope down).
Note: The Download and Clone functions require the optional #505 Astrofinder Software and Cable Connector Kit. See the instruction sheet included with the kit for more information on how to download. Download transfers information from another Autostar. During the operation, the warning “Downloading Do Not Turn Off” appears. Clone uploads information from one Autostar handbox to another.
USEFUL AUTOSTAR PROCEDURES Before trying out the examples in this section, familiarize yourself with the basic operations of Autostar described earlier in this manual. The following examples assume that you have a basic knowledge of Autostar and understand how to scroll to a desired menu or menu option, and how to enter numbers and text. It also assumes that you have initialized and aligned your telescope.
11. Press MODE. "Site: Edit" displays. 12. Using the Arrow keys, scroll to "Site: Select." The site you have just edited displays. Press ENTER to select the site or press MODE to exit. Using Autostar to Find Objects Not in the Libraries In this procedure, you will enter coordinates of celestial objects that do not appear in any of the Autostar libraries. You will enter the object's name and R.A. and Dec. coordinates (required information).
Observing Satellites In this procedure, you will prepare your telescope to observe a satellite pass. 1. Navigate to the "Object: Satellite" menu option and press ENTER. 2. Use the Scroll keys to scroll through the list of satellites. 3. Select a satellite from the list and press ENTER. 4. "Calculating...." and then "Tracking..." displays. If the satellite is going to make a pass, "Located" displays. 5.
Another setup method is to select an object from the Landmark database. See TO SELECT A LANDMARK FROM THE DATABASE below. Then manually move the telescope's optical tube and center this object in the telescope eyepiece. 2. Display the "Setup: Targets" menu option. Choose "Terrestrial" and press ENTER. "Setup: Targets" displays again. Choosing this option turns off tracking for astronomical objects which is not useful for the viewing of terrestrial objects such as those in the Landmark database.

nal of the telescope, followed by an eyepiece. The #1A Skylight Filter threads onto the rear cell of the Meade Schmidt-Cassegrain SC-8 model and effectively seals the interior of the telescope from dust. All other rear cell accessories may then be threaded to the #1A filter. The filter increases visual and photographic contrast, decreases glare, and helps to penetrate haze. #1205 Electric focuser: For use with LXD75 Schmidt-Cassegrain SC-8 model.
MAINTENANCE General Maintenance LXD75-Series telescopes are precision optical instruments designed to yield a lifetime of rewarding applications. Given the care and respect due any precision instrument, your LXD75 will rarely, if ever, require factory servicing. Maintenance guidelines include: a. Avoid cleaning the telescope’s optics: A little dust on the front surface of the telescope’s correcting lens causes virtually no degradation of image quality and should not be considered reason to clean the lens.
b c d Tip: A useful tool for making collimation easier is to make a hole in the plastic cap that comes with the eyepiece to protect it during shipping. Use a drill to make a 1/8" hole in the center of the cap and place it over the eyepiece holder for use during the collimation procedure. e Focuser drawtube Diagonal mirror Reflection of primary mirror Reflection of secondary mirror (darkened due to back lighting) f g b c d e f Primary mirror clips Reflection of observer's eye g Fig.
b c Fig. 32: Correct (1) and incorrect (2) collimation as viewed during a star test. Note: A small paper ring is attached to the primary mirror. This ring was attached at the factory for purposes of laser collimation. The ring will not diminish your telescope's imaging capabilities and does not need to be removed. 4. Perform an actual star test to confirm the accuracy of steps 1 through 3.

APPENDIX A: CELESTIAL COORDINATES A celestial coordinate system was created that maps an imaginary sphere surrounding the Earth upon which all stars appear to be placed. This mapping system is similar to the system of latitude and longitude on Earth surface maps. In mapping the surface of the Earth, lines of longitude are drawn between the North and South Poles and lines of latitude are drawn in an East-West direction, parallel to the Earth’s equator.
and also of the object you wish to locate, in a star atlas. Point the object at the bright star. Then loosen the R.A. setting circle lock knob (32, Fig. 1d) and turn the R.A. setting circle to read the correct R.A. coordinate of the bright star; lock the R.A. setting circle lock knob onto the object. Next, loosen the R.A. lock (33, Fig. 1d) and turn the telescope in R.A. to read the correct R.A. coordinate of the object. Tighten the R.A. lock (33, Fig. 1d).
APPENDIX B: ENHANCING POINTING PRECISION The Polar Alignment Viewfinder Reticle LED Knob Typically Autostar's pointing capabilities are sufficient for most telescope observers, and the use of the polar alignment viewfinder is unnecessary for them. However, for those observers who need to meet the more demanding requirements of astrophotography, the polar alignment viewfinder allows the telescope mount to be more precisely aligned with true North.
4. Autostar then chooses three stars from its database to align upon. When the telescope slews to a star for alignment, it may not appear in the field of view in the eyepiece. Use the Arrow keys to move the telescope until the star is visible and centered in the eyepiece. The alignment star should be easily recognized and be the brightest star in the area of the sky where the telescope is pointing. See WHICH ONE'S THE ALIGNMENT STAR, page 18, for more information. When the star is centered, press ENTER.
Important Note: The image will appear right-side-up, but reversed left-forright, in the eyepiece of a refractor telescope. The image will appear upside-down, but correct left-for-right, in the eyepiece of a SchmidtNewtonian telescope, if the eyepiece extends horizontally from the tube, as described in Step #3. Fig. 45: Position A. 5. Loosen the R.A. Lock (Tip: Make sure you do not accidentally loosen the Dec. Lock. If you do, restart the procedure beginning at Step #2).
A C Motor at back of mount B D Fig. 48: Method #2 Setup. (A) Optical Tube; (B) Dec. Motor; (C) Cradle Ring Lock Knobs; (D) Eyepiece. 7. Rotate the telescope 180° in the R.A. axis ONLY, to return the optical tube to position A. 8. Repeat steps 5 through 8, if necessary, alternating between position A and position B, and bringing the reference object halfway of the remaining distance to center.
The telescope first moves 180° on the Dec. axis and then rotates 180° on the R.A. axis. Autostar displays "Slewing....". When the telescope has completed the 180° slew, the telescope will be under the mount instead of over it. The counterweight shaft is now pointed upwards and the cradle adjustment screws (Fig. 47) are easily accessible. 7. Autostar again prompts you to center the landmark you have chosen in the eyepiece. Use the Arrow keys to center the object and then press ENTER. 8.
APPENDIX C: LATITUDE CHART Latitude Chart for Major Cities of the World To aid in the polar alignment procedure (see pages 17-21), latitudes of major cities around the world are listed below. To determine the latitude of an observing site not listed on the chart, locate the city closest to your site. Then follow the procedure below: Northern hemisphere observers (N): If the site is over 70 miles (110 km) north of the listed city, add one degree for every 70 miles.
APPENDIX D: EC HANDBOX 1 Important Note: The Electronic Controllers available for Meade's ETX and DS telescope series are not compatible and will not operate with the LXD75 EC series models. Do not plug in other telescope series' EC handboxes into the LXD75 computer control panel, nor plug the LXD75 EC series handboxes into any other telescope series computer control panel.

See TRACKING RATES, page 60. 6 OUT Key: Use this key to decrease the tracking rate. See TRACKING RATES, page 60. 7 IN Key: Use this key to increase the tracking rate. See TRACKING RATES, page 60. Modes of Operation • When both the A and B screws are in place, the Northern hemisphere polar mode is selected when power is applied (i.e.
7. When the test is complete, light 1 remains on; lights 2, 3, and 4 turn off. 8. Use the four Arrow keys (1, Fig. 49) to slew the telescope to the desired object. To change the slew speed, press SPEED. 9. Fine-adjust the position of the object with the Electronic Controller Arrow keys so that it is centered in the viewfinder. The object is now ready to be viewed through the telescope’s eyepiece.
Note: The tracking rate can be increased by up to 65%. 4. To use a rate slower than sidereal, press OUT (6, Fig. 49) until light 4 blinks again (sidereal rate). Press OUT key and light 4 goes out, signifying a tracking rate 0.5% slower than sidereal. Note that when the Mode function is active, the tracking motor stops. To restart the tracking motor, press MODE again. Experiment with this function to get the right speed: Press OUT to set the tracking rate. Then press MODE and look through the eyepiece.

How to Attach the Optical Tube to the Mount The LXD75 model SC-8 Schmidt-Cassegrain assembles and operates identically to all the other LXD75 models equipped with an Autostar handbox, with one exception: the optical tube is attached to the mount with a mounting bracket rather than the cradle ring assembly.
APPENDIX F: BASIC ASTRONOMY In the early 17th century Italian Scientist Galileo, using a telescope smaller than your LXD75, turned it skyward instead of looking at the distant trees and mountains. What he saw, and what he realized about what he saw, has forever changed the way mankind thinks about the universe.
Planets Planets change positions in the sky as they orbit around the Sun. To locate the planets on a given day or month, consult a monthly astronomy magazine, such as Sky and Telescope or Astronomy. You can also consult Autostar for information about planets. Scroll to the "Object: Solar System" menu and scroll through the lists of planets. When a planet you are interested in displays, press ENTER.
