Instruction Manual DS-2000 Series Reflecting and Refracting T elescopes Meade Instruments Corporation.
Refracting T elescopes 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.

Certain features of your telescope ma y look different than, or be positioned slightly different than the one pictured here, but the functionality of the features is the same.
7 An important array of features and manual controls facilitates operation of a DS-2000 tele- scope. Be sure to become acquainted with all of these controls before attempting observations through the telescope. Focus Knob - Moves the telescope’s focus drawtube in a finely-controlled motion to achieve precise image focus.
8 Accessory T ray Attachment Bolts - Attach to wing nuts (not shown) to fasten tray to the tripod. See page 1 1 for more information. Note : It is not necessar y to remove the tr ay each time y ou collapse the tripod. The tra y is designed to be collapsed with the legs.
9 Control of the DS-2000A T Series T elescopes is through the operation of the #494 Autostar handbox. Nearly all functions of the telescope are accomplished with just a few pushes of Autostar ’s buttons.
10 DEFINITION: Throughout this manu- al, you will notice the term "Alt/Az." Alt/Az is frequently used to ref er to Altitude (vertical) and Azimuth (horizon- tal). Alt/Az is just one of many methods used b y amateur astronomers to help locate stars in the night sky .
11 P acking List Getting the telescope ready for first observations requires only a few minutes. When first open- ing the packing box, note carefully the parts listed on your packing list or giftbox. How to Assemb le Y our T elescope The telescope attaches directly to the tripod.
12 10. Attach the viewfinder: Carefully remove the rubber eyecup from the viewfinder before sliding the viewfinder into the bracket. Slide the viewfinder , eyepiece-end first, into the viewfinder bracket (see Figs. 8a and 8b ). Replace the rubber eyecup after the viewfinder is positioned in the bracket.
13 Focusing the 6 x 30mm Viewfinder: The 6 x 30mm viewfinder is locked into permanent focus at infinity . Look through the viewfinder at a distant land object. If the focus is not sharp, follow this procedure: 1. Loosen the focus lock ring ( 3, Fig. 12 ) a few turns, permitting the lens cell ( 2, Fig.
14 image) has been aligned to the main telescope. Fig. 13B shows these same images after the viewfinder and main telescope are aligned. 5. Check this alignment on a celestial object, such as the Moon or a bright star , and make any necessary refinements.
15 OBSER VING Observing by Mo ving the T elescope Manually If you wish to observe a distant land object, such as a mountain top or a bird, you can observe by merely pointing the telescope and looking through the eyepiece. 1. Loosen the telescope ’ s tripod base lock knob ( 26, Fig.
16 Slew Speeds Autostar has nine slew speeds that are directly proportional to the sidereal rate (see TO TR AC K AN OBJECT A UT OMA TICALL Y below for a definition of "sidereal rate") and have been calculat- ed to accomplish specific functions.
DEFINITION: Initialization is a proce- dure that ensures that A utostar operates cor- rectly . When you first use A utostar , it doesn't yet kno w where the obser vation location site is or the time or date of the obser vation session.
18 10. Select City - The next screen asks for the city (listed alphabetically) closest to the observ- ing site. Use the Scroll keys to cycle through the database of cities. Press ENTER when the correct city appears on screen. 11 . Select Model Number - The next screen asks for the telescope model.
19 How to Easy Align Y our T elescope If you have just applied power to Autostar , perform steps 1 through 5. If you have already per- formed the initialization procedure, go to step 6. 1. Sun W arning - Press the key prompted by Autostar to accept. 2.
20 T wo-Star Alt/Az Alignment T wo-Star Alignment requires some knowledge of the night sky . T wo-Star Alignment is identical to Easy: Align (see EASY (TWO-ST AR) ALIGN , above), except Autostar displays a database of bright stars and two stars are chosen b y the observer from this database for alignment.
21 It is important to understand that menu selections are set in a loop ( Fig. 20 ). This means that pressing the Scroll Down key ( 7, Fig. 2 ) cycles down through all the available options within a given category , then returns to the first option. The Scroll Up key ( 6, Fig.
22 T o Calculate Sunset time: 1. Press the MODE key several times, until “ Select Item: Object ” is displayed. 2. Press the Scroll Down key once to display the “ Event ” option in the “ Select Item ” menu. 3. Press the ENTER key to choose the "Event" option and move down a level.
23 MENUS AND MENU OPTIONS Object Menu Almost all observing with Autostar is performed using the Object menu category . ( NOTE: Exceptions include Guided T our and Landmark Sur ve y . ) See GO TO SA TURN , page 20, for an example of observing using the Object menu.
24 Landmarks stores the location of terrestrial points of interest in the permanent Autostar data- base. IMPORT ANT NOTE: T o use the Landmark function, the telescope must be located and aligned e xactly as when the landmark was added to the database.
25 A utumn and V ernal Equino x calculates the time and date of the fall or spring equinox of the current year . Winter and Summer Solstice calculates the time and date of the winter or summer solstice of the current year .
26 ■ Suggest: Autostar calculates and suggests the best eyepiece for viewing, based on the telescope and the object being viewed. Display Options enables or disables Autostar ’ s two initial displays. If both displays are dis- abled, Autostar begins with the Date display .

35 Celestial Coordinates It is helpful to understand how to locate celestial objects as they move across the sky . 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.
APPENDIX B 36 Using A utostar to Find Objects Not in the Database Although Autostar contains a database of more than 1400 celestial objects (stars, nebulae, planets, etc.) that you can observe, you may eventually want to view objects that are not part of the database.
37 Observing Satellites In this procedure, you will prepare your telescope to observe a satellite pass. 1. Go 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.
38 T raining the Drive T rain the telescope motors using Autostar . Perform this procedure if you are experiencing any pointing accuracy prob- lems. Fig. 32 depicts the complete Drive T raining procedure. NO TE: Use a terrestrial object, such as a telephone pole or lamp post, to train the drive.

40 Slew Speeds The Electronic Controller has four slew speeds that are directly proportional to the sidereal rate (see page 16 for more information). Press the Speed key to change the slew speed. Note each slew speed corresponds to one of the four LED's of the Electronic Controller .
41 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.
42 Planets Planets change positions in the sky as they orbit around the Sun. T o locate the planets on a given day or month, consult a monthly astronomy magazine, such as Sky and T elescope or Astronomy . Y ou can also consult Autostar for information about planets.
