Instruction Manual DS-114A T Reflecting T elescope Meade Instruments Corporation.
Reflecting T elescopes use a concave primary mirror to collect light and form an image. In the Newtonian type of reflector , light is reflect- ed by a small, flat secondary mirror to the side of the main tube for observation of the image. Light is collected by a concave mirror and brought to a focus at F .

4 QUICK-ST AR T GUIDE 1. Remove the optical tube and tripod fr om the gift- bo x. Perform this setup on a flat, stable surface. It is rec- ommended that you perform this operation in the day- time or in bright light the first time you assemble the tel- escope.
5 6. Adjust tripod. Adjust the height of the tripod by lifting the clip on each leg and extending the sliding inner section of each tri- pod leg to the desired length. Then press the clip back against the leg to lock in place. 4. Attach and balance the optical tube.

7 The DS-1 14A T telescope has a variety of useful features. Be sure to become acquainted with all of these controls bef ore you begin making observations through the telescope. Focus Knobs : Move the telescope’s focus drawtube in a finely-controlled motion to achieve precise image focus.
8 Control of the DS-1 14A T Series T elescopes is through the operation of the #494 Autostar handbox. Nearly all functions of the telescope can be operated with just a few pushes of Autostar ’s buttons.
9 Arro w Keys : Move the telescope in a specific direction (up, down, left, and right), at any one of nine different slew speeds. The Arrow Keys can also be used to scroll through the letters of the alphabet and numeri- cal digits. The Down Arrow key starts with the letter "A" and the Up Arrow key starts with the digit "9.
10 P acking List Assembling the telescope for the first time requires only a few minutes. When first opening the packing box, note carefully the parts listed on your giftbox. How to Assemb le Y our T elescope The telescope attaches directly to the tripod.
11 12. Connect Autostar: Plug the coil cord of the Autostar Controller into the HBX port ( C, Fig.1b ) of the computer control panel. W ARNING: Make sure you plug in Autostar before you plug in the battery pack. NO TE: A utostar does not require batteries; the telescope’ s batter ies supply power to A utostar .
DEFINITION: A capital "X" is used to denote an ey epiece's (or a Barlow's) power or magnification. For e xam- ple, "40X" is read as "40-power ." 12 Aligning the Viewfinder: It is recommended that you perform steps 1 through 4 of this procedure during the daytime and step 5 at night.
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 Az lock ( 19, Fig.
Fig. 18: Alt/Az Home Position. North Level the opti- cal tube 14 5. The Arrow keys are now activated. Press the Arrow keys ( 5, Fig. 2 ) to slew (move) the tel- escope up, down, right, or left. 6. Press the SPEED/? key ( 8, Fig. 2 ) to change the telescope ’ s slew speed.
DEFINITION: Initialization is a procedure that ensures A utostar operates correctly . When you first use A utostar , it doesn't yet kno w where the obser vation site is or the time or date of the obser vation ses- sion. During the procedure, you will enter inf or- mation, such as the current time and date, and observa- tion location.
16 10. Select City : The next screen asks for the city closest to the observing site. Use the Scroll keys to cycle through the database of cities (listed alphabetically). Press ENTER when the correct city appears on screen. 11 . Select Model Number : The next screen asks for the telescope model.
17 Observe a Star using the Automatic T rac king Feature In this example, the Autostar Arrow keys are used to find a star , and then Autostar's tracking capability automatically keeps the star centered in your telescope's eyepiece. 1. Set in Home P osition: Level the optical tube and point it North.
18 5. Daylight Sa vings - Select “ Ye s ” or “ No, ” then press ENTER. 6. Alignment Option Screen - “ Setup: Align ” displays. Press ENTER. 7. Select Alignment - “ Align: Easy ” displays. Press ENTER. 8. Set Alt/Az Home P osition - Autostar then prompts you to set the telescope in the Alt/Az Alignment home position.
19 Go T o Saturn After performing the Easy Align procedure, the motor drive begins operating and the telescope is aligned for a night of viewing. Objects in the eyepiece should maintain their position even though the Earth is rotating beneath the stars.
20 It is important to understand that menu selections are set in a loop ( Fig. 23 ). 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.
21 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.
22 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 Landmar k Surve y . ) See GO T O SA TURN , page 19, for an example of observing using the Object menu.
23 Landmarks stores the location of terrestrial points of interest in the permanent Autostar data- base. IMPORT ANT NO TE: T o use the Landmark function, the telescope must be located and aligned e xactly as when the landmark was added to the database.
24 Solar Eclipse lists upcoming Solar Eclipses, including the date and type (total, annular , or par- tial) of eclipse, and the location and time of the first and last contacts of the Moon's shadow . Use the Scroll Up and Down keys to display the available data.
25 Display Options enables or disables Autostar ’ s two initial displays. If both displays are dis- abled, Autostar begins with the Date display . ■ Sun W arning: Turns the “ Sun W arning ” message on or off. ■ Getting Started: Turns the “ Getting Started ” message on or of f.
26 T elescope accesses the several options, including: ■ Model: Allows you to select the telescope model connected to Autostar . ■ Focal Length: Displays the focal length of the selected telescope. ■ Az Ratio and Alt Ratio : The Az (Azimuth) ratio and Alt (Altitude) ratio refers to the gears of the telescope's motors.
27 ■ Edit : Edits a selected site, including: the name, latitude, longitude, and time zone. T ime Zone refers to the Greenwich Mean T ime (GMT) time zone shift. Users W est of Greenwich, England use “ - ” hours, East of Greenwich use “ + ” hours.
28 CARING FOR Y OUR TELESCOPE Y our DS-1 14A T telescope is a precision optical instrument designed to yield a lifetime of rewarding observations. Given the care and respect due any precision instrument, your tele- scope will rarely , if ever , require factory servicing.

31 OPTIONAL A CCESSORIES A wide assortment of professional Meade accessories is available for the DS-1 14A T T elescopes. The premium quality of these accessories is well-suited to the quality of the instru- ment itself. Consult the Meade General Catalog for complete details on these and other accessories.
32 Locating the Celestial P ole T o get basic bearings at an observing location, take note of where the Sun rises (East) and sets (West) each day . After the site is dark, face North by pointing your left shoulder toward where the Sun set. T o precisely point at the pole, find the North Star (Polaris) by using the Big Dipper as a guide ( Fig.
APPENDIX B 33 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.
34 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.
35 In the early 17th century Italian Scientist Galileo, using a telescope smaller than your DS-1 14A T 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.
