Instruction Manual DS-2000 Series Reflecting and Refracting Telescopes AutoStar® — LNT™ — SmartFinder™ ™ MEADE.
Refracting Telescopes use a large objective lens as their primary light-collecting element. Meade refractors, in all models and apertures, include achromatic (2-element) objective lenses in order to reduce or virtually eliminate the false color (chromatic aberration) that results in the telescopic image when light passes through a lens. Reflecting Telescopes use a concave primary mirror to collect light and form an image.

AUTOSTAR FEATURES NOTE: DS-2000EC users, see APPENDIX E, page 39, for information about your supplied Electronic Controller. Autostar information does not apply. The #494 Autostar controls the DS-2000AT Series Telescopes. Nearly all telescope operations are accomplished with just a few pushes of Autostar’s buttons. Some of the major features of Autostar are: DS-2000EC users may obtain the #494 Autostar handbox as an optional accessory. See page 42 for more information.
DEFINITION: Throughout this manual, you will notice the term "Alt/Az." Alt/Az (short for altazimuth) just means that your telescope moves up and down and from side to side. Alt/Az is one of many methods used by amateur astronomers to locate celestial objects. telescope is slewing, the operation may be aborted at any time by pressing any key except GO TO. Pressing GO TO again resumes the slew to the object. The GO TO key also allows you to perform a "spiral search.
GETTING STARTED Packing List Getting the telescope ready for first observations requires only a few minutes. When first opening the packing box, note carefully the parts listed on your giftbox. How to Assemble Your Telescope The telescope attaches directly to the tripod. The telescope in this way is mounted in an “Altazimuth” (“Altitude-Azimuth,” or “vertical-horizontal”) format. The telescope in this configuration moves up and down and from side to side. Fig. 6: Attach cradle to mounting arm. 1.
b). Insert the tongue into the SmartFinder slot. Angle the tongue towards the front of the LNT module as you slide it into place. See Fig. 9. Fig. 9: Attach Smartfinder lens; slide “tongue” into slot. c) You may need to wiggle the lens/tongue a bit to slide the tongue into place. You will hear it “click” in place. for a view of the underside of the LNT. Notice that the tongue has slid in over the small plastic molded post.
4. Press the Scroll Down key. “Finder: Blink On” displays. 5. Press ENTER. A time value, in seconds, displays.

Press the Scroll Down key. “Finder: Blink Off” displays. 7. Press ENTER. Use the Number keys to enter “00.0” or press the Scroll Down key until “00.0” displays. “00.
Choosing an Eyepiece Important Note: When you look through your telescope’s eyepiece, the image might look strange at first. If you have a refracting telescope, objects will appear right-side-up, but reversed left-for-right. This will not make a difference when observing astronomical objects, and in fact, all astronomical telescopes present inverted images.
NOTE: Do not look through the telescope's eyepiece while it is rapidly moving. Children should always have adult supervision while observing. Terrestrial Observing DS-2000 refracting telescopes are excellent high-resolution, terrestrial (land) telescopes (reflecting telescopes are designed primarily for astronomical observations). Viewing terrestrial objects requires looking along the Earth's surface through heat waves. These heat waves often cause degradation of image quality.
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 a standard 25mm eyepiece. Speeds 7 or 8: Best used for rough centering of an object in the eyepiece. Speed 9: Moves the telescope quickly from one point in the sky to another.
Initializing Autostar This section describes how to initialize Autostar. Perform this procedure the first time you use Autostar or after performing a RESET (see RESET, page 28). Fig. 17: Altitude lock and setting circle. DEFINITION: Initialization is a procedure that ensures that Autostar operates correctly. When you first use Autostar, it doesn't yet know where the observation location site is . Time and Date information is set at the factory (and do not need to be entered by the observer).
IMPORTANT NOTE: Autostar requests the Zip Code or Country/State, City, and Telescope Model information only the first time Autostar is activated. If you wish to change this information, use the "Site" and "Telescope Model" options in the Setup menu. See pages 26 and 27 for more information. IMPORTANT NOTE: While performing the automatic tracking procedure, only use the Arrow keys to move the telescope.
NOTE: Autostar locates alignment stars based on the date, time, and location entered. The alignment stars may change from night to night. All that is required is for the observer to center the selected stars in the eyepiece when prompted. NOTE: The GO TO key also allows you to perform a "spiral search." A spiral search is useful when the telescope slews to an object, but that object is not visible in the eyepiece after the telescope finishes its search. (This sometimes occurs during an alignment procedure.

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 19, for an example of observing using the Object menu. Also see TAKE A GUIDED TOUR, page 19. Many Autostar menu categories contain databases. An Autostar database is a list of viewable objects, such as stars, planets, comets, nebulae, and so forth.
Event Menu The Event menu provides access to dates and times of astronomical events. The Event database includes: Sunrise and Sunset calculates the time that the Sun rises or sets on the current date. Find rise and set times for other dates by entering a new date into the “Setup: Date” menu. See DATE, page 26. Moonrise and Moonset calculates the time that the Moon rises or sets on the current date. Find rise and set times for other dates by entering a new date into the “Setup: Date” menu. See DATE, page 26.

BASIC ASTRONOMY In the early 17th century Italian Scientist Galileo, using a telescope smaller than your DS-2000 model, 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.
