Instruction Manual DS-2000 Series Reflecting and Refracting Telescopes 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 40 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.
11. Insert the eyepiece: Remove the supplied eyepiece (3, Fig. 9) from its container and place it in the diagonal prism (refractor models only; 1, Fig. 9) or directly into the eyepiece holder (2, Fig. 10, reflector models only). Tighten the thumbscrews (2 and 4, Fig. 9, refractor models only) to a firm feel only. Tighten the thumbscrew (3 , Fig. 10, reflector models only) to a firm feel only. 3 2 12. Insert batteries: The telescope’s battery compartment (1, Fig. 11) is located on top of the drive base.
5. Intensity Slider Check this alignment on a celestial object, such as the Moon or a bright star, and make any necessary refinements. Choosing an Eyepiece A telescope’s eyepiece magnifies the light gathered by the optical tube. Each eyepiece has a focal length, expressed in millimeters, or “mm.” The smaller the focal length, the higher the magnification. For example, an eyepiece with a focal length of 9mm has a higher magnification than an eyepiece with a focal length of 25mm. Fig.
OBSERVING 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. During terrestrial observing, when a corrected image (rightside up and correct leftfor-right) is desirable, an optional Meade 45° Erecting Prism is available.
NOTE: Do not look through the telescope's eyepiece or viewfinder while it is rapidly moving. Children should always have adult supervision while observing. TIP: When a message is scrolling across the display, press and hold the Up Arrow key to increase the scrolling speed or press and hold the Down Arrow key to decrease the scrolling speed.

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.
