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. In the Newtonian type of reflector, light is reflected by a small, flat secondary mirror to the side of the main tube for observation of the image.
Refracting Telescope
In the refracting telescope, light is collected by a 2-element objective lens and brought to a focus at F.
Reflecting Telescope
In contrast, the reflecting telescope uses a concave mirror for this purpose.
WARNING!
Never use a Meade®Telescope to look at the Sun! Looking at or near the Sun will
cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope or its viewfinder at or near the Sun. Do not look through the telescope or its viewfinder as it is moving. Children should always have adult super­vision while observing.
CAUTION:
Use care to install batteries as indicated by the battery compartment. Follow battery manufactur­er's precautions. Do not install batteries backward or mix new and used batteries. Do not mix battery types. If these precautions are not followed, bat­teries may explode, catch fire, or leak. Improperly installed batteries void your Meade warranty.
If you are anxious to use your DS Astro Telescope for the first time, before a thorough reading of this instruction manual, see the QUICK-START GUIDE on page 4.
IMPORTANT NOTE: DS-2000EC users
for information about your supplied Electronic Controller. Autostar information does not apply.
DS-2000EC users may obtain the #494 Autostar handbox as an optional accessory. See page 42 for more information.

AUTOSTAR FEATURES
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:
N Automatically move the telescope to any of the 1400 objects stored in the database or man-
ually enter the astronomical coordinates of any celestial object.
N Take a guided tour of the best celestial objects to view on any given night of the year.
N Access a glossary of astronomical terms.
N Calculate which eyepiece to use for optimum viewing of a celestial object.
The Autostar Computer Controller provides control of virtually every telescope operation.
utostar has soft-touch keys designed to have a positive feel. The LCD (Liquid Crystal Display)
A is backlit with a red LED (Light Emitting Diode) for easy viewing in the dark. The backlit display, key arrangement, and sequential database make Autostar extremely user friendly.
NOTE: Autostar does not require batteries; the telescope’s batteries supply power to Autostar.

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 tr “Altazimuth” (“Altitude-Azimuth,” or “vertical-horizontal”) format. The telescope in this configuration moves up and down and from side to side.
1. Open the tripod: After removing the field tripod from its shipping carton, stand the tripod vertically, with the tripod feet down and with the tripod still fully collapsed. Gently pull the legs apart to a fully open position.
Attach the tray to the tripod: Place the tray (19, Fig. 1) over the inner support strut that
2. contains two bolt holes. Line up the bolts holes on the tray with the bolt holes on the strut. Slide the two included bolts through the top of bolt holes ( with the included wing nuts on the bottom side of the tray (Fig. 3). Tighten to a firm feel only.
Note: The tray does not have to be removed when you collapse the tripod at the end of a viewing session— just loosen the tray’s center lock knob.
3. Secure the tripod: Turn the center tripod lock knob (Fig. 4) to help stabilize and secure the tripod.
Caution: Make sure that you loosen the tripod lock knob before collapsing the tripod.
4. Attach the mounting arm assembly to the tripod base: There are three pads in the tri- pod base ( allow the mounting arm assembly to move more easily inside the base.
Place the mounting arm assembly into the tripod base and continue to hold onto the arm assembly. With your other hand, reach underneath the base and thread the mounting lock knob ( to a firm feel only; do not overtighten. While observing, you may wish to loosen this knob and rotate the mounting arm assembly and optical tube ( axis.
Remove the optical tube assembly from the cradle rings: The optical tube assembly is
5. shipped with the cradle rings attached. The rings need to be removed before they can be attached to the mounting arm. Loosen the cradle lock knob (14, Fig. 1) until you can open the cradle rings. Remove the optical tube assembly (
6. Remove 4 screws from the mounting arm shaft: Locate the four screws on the mount- ing shaft. Remove the screws using a "+" (Phillips head) screwdriver. Set the screws aside.
7. Attach the cradle to the mounting arm: Line up the cradle with the mounting arm shaft. The cradle contains a molded "key" that fits into a slot on the shaft. Line up the key and the slot, and slide the cr the cradle with the ones on the shaft. Replace the four screws into the mating threads using the Phillips head screwdriver ( telescope so that it doesn't strike the base or pass beyond approximately 90° upright when you use the Autostar handbox.

8. Use these menus to set other blink rates. For example, If you select “00.1” in the Blink Off menu, and “00.2” in the Blink On menu, the red dot will blink on for .2 seconds and then blink off for .1 second, and then repeat the cycle until
you change the values again.

Aligning Smartfinder
Because the main telescope has a fairly narrow field of view, locating objects directly in the main telescope can sometimes be difficult. Smartfinder (7, Fig. 1) projects a small red dot that permits you to more easily locate objects. When Smartfinder and optical tube are aligned to each other, both point to the same position in the sky. An object located in the viewfind­er is therefore in the eyepiece of the main telescope.
To align Smartfinder:
It is recommended that you perform steps 1 through 4 of this procedure during the day­time and step 5 at night.
1. Loosen the tripod base lock knob (
26,
Fig. 1) and the Altitude lock (10, Fig. 1),
so that the telescope can move freely.
2. If you have not already done so, place a low-power (
e.g., 25mm) eyepiece in the diagonal prism of the main tele­scope (
3, Fig. 1) and point the tele-
scope at an easy-to-find land object
.g.,
e
the top of a telephone pole or
( sign). Turn the focuser knob (
1, Fig. 1) to focus the image in the eyepiece. Center the object precisely
3. Re-tighten the tripod base lock knob (

Too Much Power?
Can you ever have too much power? If you’re referring to eyepiece power (magnification), yes, you can! The most common beginner’s mistake is to “overpower” a telescope by using too high of a magnification, which the tele­scope’s aperture and atmospheric conditions cannot reasonably support. Keep in mind that a smaller, but bright and well-resolved image is far superior to one that is larger, but dim and poorly resolved (see below). Powers above 200X should be emplo steadiest atmospheric conditions.
Autostar can calculate the best eyepiece for you to use.Try out the “Eyepiece Calc” feature in the Utilities men
Most observers should have three or four additional e of reasonable magnifications possible with the DS-2000 telescopes. See “OPTIONAL

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. an eyepiece with a focal length of 25mm.
Your telescope comes supplied with a low-powered 25mm or 26mm eyepiece which gives a wide, comfortable field of view with high image resolution. Always begin your observations with this eyepiece.
Low power eyepieces offer a wide field of view, bright, high-contrast images, and eye relief dur­ing long observing sessions. After an object is located and centered in the eyepiece, try switch­ing to a higher po
The power, or magnification of a telescope is determined by the focal length of the telescope and the focal length of the eyepiece being used. To calculate eyepiece power, divide the tele­scope's focal length by the eyepiece's focal length. For example, you may wish to use a 25mm eyepiece with the DS-2000 model DS-2114S. Look up the focal length of the DS-2114S under
SPECIFICATIONS: DS-2114S, page 33. The focal length is listed as 1000mm.
Telescope focal length divided by Eyepiece focal length = Eyepiece power
The eyepiece power, or magnification is therefore 40X (approximately).
For example, an eyepiece with a focal length of 9mm has a higher magnification than
wer eyepiece to enlarge the image.
NOTE: Viewing conditions vary from night-to-night and from site-to-site. Turbulence in
the air, even on an apparently clear night, can distort images. If an image appears fuzzy and ill-defined, return to a lower power eyepiece for a more well-resolved image.
1000 v 25 = 40
The Barlow Lens
Some Meade telescopes include a power multiplier called a Barlow lens. Consisting of a lens mounted in a 4"-long (10cm) tube, the Barlow doubles or triples the power obtained when an eyepiece is used alone. In the example above, a 25mm eyepiece results in 40X magnification with the DS-2114S telescope; when this same eyepiece is used in conjunction with a 2x Barlow lens, power is doubled to 80X. To use the Barlow, insert it into the diagonal prism (
models only) or eyepiece holder, followed by the eyepiece.

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. Lower power eyepieces, such as a 25mm eyepiece, mag­nify these heat waves less than higher power eyepieces. Therefore, lower power eyepieces pro­vide a steadier, higher quality image. If the image is fuzzy or ill-defined, reduce to a lower power
yepiece, where the heat waves do not have such an effect on image quality. Observing in early
e morning hours, before the ground has built up internal heat, produces better viewing conditions than dur
ing late afternoon hours.
