Page 9: Unpacking And Inspection
Carefully unpack and remove all the telescope parts from their packing material. Compare each part to the product identification label on the outside of each carton. In the case of the LX200 Accessory carton, a seperate list of items is enclosed identifying each item in that carton. You may wish to place a check next to each item as you identify it.
Page 10 Serious damage to the drive gears may result from shock in handling, while transporting or commercially shipping the LX200, should the R.A. Lock (7, Fig. 3), and/or the Dec. Lock (2, Fig. 4) be left engaged. Always release the locks when storing in the optional case, or when crating for commercial shipment to allow the telescope to give, if the shipping container is sharply jarred or dropped.
Page 11 (If you have misplaced the red-headed bolt, you may use any other bolt that is 1/4-20x1" long. 3. When packaging the 10" or 12" LX200, be sure to release the R.A. Lock (7, Fig. 3), and Dec. Lock (2, Fig. 3), to prevent shock to the gears in the motor assemblies.
Page 12: Telescope Assembly
1. The Field Tripod (7", 8", 10" and 12" LX200 Models) The Field Tripods (Figs. 1 and 2) for Meade 8", 10", and 12" LX200 telescopes are supplied as completely assembled units, except for the spreader bar (4, Fig. 1) and the 6 lock knobs (2 knobs for each of the 3 tripod legs) used to adjust the height of the tripod.
Page 13: Precautionary Notes
Position the spreader bar so that the 3 arms of the spreader bar are lined up with the 3 tripod legs. Place the entire telescope (as shown in Fig. 3) onto the top of the tripod head, and thread the threaded rod into the central threaded hole in the bottom of the drive base of the telescope.

Page 15 2. Mounting the Viewfinder (7", 8", 10", and 12" LX200 Models) Each 7", 8", 10", and 12" LX200 telescope is supplied as standard equipment with an 8x50mm straight- through viewfinder. The bracket for this viewfinder is packed separately from the finder itself, and 6 black nylon thumbscrews for collimation are pre-threaded into the viewfinder bracket.
Page 16 Using the 26mm eyepiece, point the main telescope at some easy to find land object (e.g., the top of a telephone pole or corner of a building) at least 200 yards distant. Center a well-defined object in the main telescope. Then, simply turn the 6 nylon collimation thumbscrews (2, Fig.
Page 17 45. This will give the number of degrees of southern horizon that the 12" LX200 will not move to. For example, if the latitude of the observing site is 35°, then 10° (45-35) of southern sky is unavailable for observations.
Page 18 The fan will operate when a special power cord (supplied in the accessory box) is plugged into the fan and the LX200 panel plug marked "Aux," and with the power switch in the "On" position. The amount of time required to stabilize the temperature will be dependent upon ambient conditions including the observation site and preexisting condition of the telescope.
Page 19: Quick Start
If you are reading this manual for the first time and are anxious to "look through the telescope," this section will describe how to use the telescope without going through the rest of the manual. But be sure to come back and read the details, for most of the telescope's features can not be accessed without a full knowledge of these details.
Page 20 2. Using the LX200 In Land The 7", 8", 10", and 12" LX200 telescopes are shipped with the microprocessor set to Land, the align menu option you will wish to use to view terrestrial objects. In this menu option 4 different motion speeds are active, allowing the telescope to be moved electronically by means of the Keypad.
Page 21 Later, see Section G, LX200 Modes for detailed instructions. These steps will only take a few minutes and will allow you to begin making use of all the LX200 features. Note also, much of this information can be skipped if using the UNKNOWN site.
Page 22 15 minute increments or better. The accuracy of the LX200 will depend on how close you get, so take a little time to get as accurate as you can.
Page 23 10. Press MODE again to go back to Display 1. It is important to note that the longitude standard used in the LX200 starts at 0° in Greenwich, U.K. and increases Westerly only to 359° 59mins. Many maps will show Easterly longitudes which cannot be entered into the Keypad Display.
Page 24 6. Use the number keys to enter the GMT time zone shift. Press ENTER when done; the display will go back to Display 8. If using the LX200 East of Greenwich U.K., enter a - (minus) GMT time zone shift by moving the blinking cursor backwards in the display with the W key, then press the NEXT key.

Page 26 Meade Instruments Corporation - Meade LX200 Instruction Manuals fork arm. The LX200 will track an overhead object, but it does so by moving higher in Altitude up to the illegal position, then the drive speeds up and move 180° in Azimuth so that the optical tube assembly can now be lowered in Altitude to keep up with the overhead object.
Page 27 If not done correctly, this can be very dangerous. The LX200 "knows" where the planets are in relation to the Sun, but the telescope does not "know" where the Sun actually is. When the GO TO button is pushed, the telescope will slew to the object by the most direct route, which may move directly over the Sun.

Page 29 LED flashlight! You will find within a few minutes of powering up the LX200 that the Keypad becomes warm, which is normal for the system. The electronics utilize a heat sink as a means to provide the right operating environment temperature for the LCD display even in sub-zero weather.
Page 30 5. Speed Keys (SLEW, FIND, CENTER, and GUIDE) These keys (6, Fig. 6) allow you to set the rate of movement or slew speed in the drives of the LX200, as activated by the N, S, E, and W keys. The chosen rate is indicated by the speed indicator illuminated LED beside the rate key that you have pressed.
Page 31 9. Object Keys (M, STAR, and CNGC) These keys (10, Fig. 6) allow direct access to the LX200's Object Library any time that you are not editing a value or setting a parameter, or selecting a file menu. Use the Object keys when you are at a "top level" of a mode.

Page 33 Meade Encoders* that will update the Keypad even if you move the LX200 manually (not using the N, S, E, W keys), the optional Meade #1206 Electric Focuser*, and an illuminated reticle eyepiece*. There is even a connector for RS-232 communication that will allow you to perform every function of the Keypad from your personal computer.
Page 34 Before power up, the appropriate N or S switch position should be made, as the LX200 will not recognize a change made on the N/S switch afterwards. Use a pen or small tool to slide the switch appropriately. Be sure before you travel across the equator, that you are setting the proper + or - latitude SITE entry for your final destination.
Page 35 The RS-232 connector (2, Fig. 7) allows personal computer interface to allow communications at 9600 baud to access every feature of the LX200 Keypad. In Appendix F of this manual is a wiring schematic to make your own RS-232 connector cord, a cord test program, a demonstration program, and the LX200 Command Set for writing programs.

Page 37: Mode Functions
LX200 is first turned on. The TELESCOPE/OBJECT LIBRARY mode can be thought of as command central. It is here that we can select the way that we want the LX200 to perform mechanically, and where we can explore and select from its extensive library of stored objects.
Page 38 You can choose any one of the four site selections at your convenience, without the bother of entering longitude and latitude every time you use the LX200. Once the site is chosen, exit the SITE menu by pressing the MODE key.
Page 39 (2) Follow the Keypad display prompts to select and center the two alignment stars. As described above, the LX200 will check the accuracy of the two stars and give the "Align Mismatch - Check Stars" message if it detects an error.

Page 44 - including CCD imaging with larger chip cameras, like the Meade Pictor 416 and Pictor 1616 CCD cameras. The HP feature increases the pointing accuracy of the LX200 to 1 arc-minute or better and also requires the "critical" alignment procedure described above. This alignment procedure will yield the best pointing accuracy possible, placing images of objects onto the active area of the even the smallest CCD cameras available.
Page 45 POLAR mode.)To program the Dec. backlash, use the following procedure: 1. Move to option #11 from the TELESCOPE menu. The Keypad display will show: The "00" in the display shows the number of arc-seconds of backlash the LX200 is set to compensate for (the default setting is 0 arc-seconds).

Page 48 LX200 will not try to find objects below your setting.
Page 49 You may want to adjust the magnitude level to a brighter value starting at perhaps the limiting visual magnitude of your LX200, which is approximately 14.0 for an 8" and 14.5 for a 10". If you are making astrophotographs, the limiting magnitudes are about 16.5 and 17 for the eight and ten inch instruments respectively.
Page 50 The GO TO menu option, allows you to enter new Right Ascension and Declination coordinates of any object in the sky, so that the LX200 will slew to the new position. With this ability, your LX200 knows no bounds, any celestial object, including comets, asteroids, etc. are easily found, provided you have accurate coordinate data to refer to.
Page 51 FREQ= Menu File FREQ= (Frequency) allows you to adjust the tracking speeds (not slew speeds) of the LX200 digitally in tenths of a hertz from 56.4 Hz to 60.1 Hz, so that you can match virtually every celestial motion in the sky.

Page 53: Magnification And Field Of View
Under very steady atmospheric "seeing," the 7" LX200 may be used at powers up to about 450X on astronomical objects, the 8" LX200 may be used at powers up to about 500X, the 10" LX200 up to about 600X and the 12" up to about 750X. Generally, however, lower powers of perhaps 250X to 350X will be the maximum permissible, consistent with high image resolution.
Page 54 A reasonable magnification range for daytime terrestrial observations through the 7" LX200 is from about 70X to 180X; 8" LX200 is from about 80X to 190X; through the 10" LX200 from about 100X to 200X, the 12" LX200 from 120X to 240X. It should be noted, however, that the higher magnifications may not be used due to severe air turbulence near the ground.

Page 56: Appendix A: Equatorial Wedge
The wedge should never be used without the field tripod, e.g. by placing the wedge alone on a table top and then mounting the telescope on the wedge. The 7" or 8" LX200, placed onto the equatorial wedge alone without the field tripod attached to the wedge may become seriously imbalanced, to the point where the telescope may actually tip over.
Page 57 Meade Instruments Corporation - Meade LX200 Instruction Manuals Figure 8: Equatorial Wedge for 7" and 8" LX200 Telescope To assemble the equatorial wedge, follow this procedure (note that all required wedge hardware and manual knobs are shipped within the wedge carton): 1.
Page 58 Meade Instruments Corporation - Meade LX200 Instruction Manuals 3. Attach the Azimuth Base to the Field Tripod using the 2 ea. 8-32 x 1" round-head machine screws. 4. Thread the two Azimuth Adjustment Knobs into the Azimuth Base, until they just touch the Azimuth Arm.
Page 59 Superwedge should never be used without the field tripod, e.g. by placing the Superwedge alone on a table top and then mounting the telescope on the wedge. The 10" and 12" LX200, placed onto the Superwedge alone without the field tripod attached to the wedge may become seriously imbalanced, to the point where the telescope may actually tip over.
Page 60 3. Mounting the Telescope On the Wedge (7", 8", 10", and 12" LX200 Models) With 7" or 8" LX200 telescopes, three knobs are supplied for mounting the telescope's drive base to the tilt- plate of the equatorial wedge. With the 10" and 12" LX200, three socket screws are provided for this purpose.
Page 61 Meade Instruments Corporation - Meade LX200 Instruction Manuals Thread one of these knobs (or screws, as appropriate) partially into the hole on the underside of the drive base, located at the curved-end of the drive base. See 4, Fig. 12. This knob or screw should be threaded in about 3 full turns, not fully threaded into the hole.

Page 81: Appendix D: Lx200 64,359-Object Library
The coordinates in the CNGC listing are listed for the year 2000. The LX200 calculates object positions upon power up to the current date (as shown on the time/date display). This makes the LX200 pointing more accurate. Therefore, the CNGC listing and the LX200 display will not exactly agree on object positions.
Page 82 Meade Instruments Corporation - Meade LX200 Instruction Manuals will vary, largely due to sky conditions. If the object has been rated by observation, an upper-case character (ABCDEFG) is used for the VQ on the CNGC listing. If the object has not been observed, the VQ has been estimated by a computer program from the object type, size, and brightness and the VQ is specified in lower-case characters (abcdefg).

Page 87: Appendix E: Maintaining Your Lx200
It is also advisable that you let the optional foam lined case for the LX200 dry out indoors for a day if the night was moist. Packing your telescope away in a moist case can result in giving it a steam bath later.
Page 88 Meade #50 Accessory case*. All of the non optical surfaces of the LX200 should be cleaned routinely with a soft rag and alcohol to prevent corrosion. The cast metal surfaces and the individual exposed screws can also be kept looking new and corrosion free by wiping them down with a water displacement solution (such as WD-40).
Page 89 To reduce the chance of interior contamination, the Meade Skylight 1 A Dust Seal is very effective. If the Dust Seal is not used, it helps to have the rear cell pointed downward when replacing the rear dust cover or attaching accessories.
Page 90 Fig. 26: Coillimation of the Optical System (1), (2), (3) Set screws for adjusting collimation. To check the collimation of your LX200, center a bright star that is overhead, or use a reflected "hot spot" of reflected sunlight from a chrome car bumper or a telephone pole insulator, with the supplied 26mm eyepiece.
Page 91 (1, Fig. 27), place your index finger in front of the telescope so that it touches one of the collimation set screws. You will see the shadow of your finger in the ring of light.
Page 92 3. Adjusting the Right Ascension Lock After a period of time, it is possible that the R.A. lock (7, Fig. 3) of the LX200 will not tighten sufficiently due to internal wear of the clutch mechanism. In such an event, remove the R.A. lock lever using one of the hex wrenches supplied with the telescope.
