thread inward one of the adjustment/lock knobs (1, Fig. 24) while unthreading another of these knobs. Only make adjustments to two knobs at a time until the secondary mirror appears as in Fig. 28.

3.Secondary mirror-holder adjustments: If the secondary mirror (1, Fig. 28) is centered in the focuser drawtube (2, Fig. 28), but the primary mirror is only partially visible in the reflection (3, Fig. 28), the three “+” (Phillips head) secondary mirror-tilt screws (2, Fig. 24) should be slight- ly unthreaded to the point where the secondary mirror-holder (3, Fig. 24) can rotate about its axis parallel to the main tube. Grasp the secondary mirror-holder (avoid touching the mirror sur- face!) with your hand and rotate it until, looking through the drawtube, you can see the primary mirror centered as well as possible in the reflection of the secondary mirror. With the rotation of the secondary mirror-holder at this best-possible position, thread in the three Phillips head screws (2, Fig. 24) to lock the rotational position. Then, if necessary, make adjustments to these three Phillips head screws to refine the tilt-angle of the secondary mirror, until the entire primary mirror can be seen centered within the secondary mirror’s reflection. With the second- ary mirror thus aligned the image through the drawtube appears as in Fig. 29.

4.Primary mirror adjustments: If the secondary mirror (1, Fig. 29) and the reflection of the pri- mary mirror (2, Fig. 29) appear centered within the drawtube (3, Fig. 29), but the reflection of your eye and the reflection of the secondary mirror (4, Fig. 29) appear off-center, then the pri- mary mirror tilt requires adjusting, using the Phillips head screws of the primary mirror cell (3, Fig. 25). These primary mirror-tilt screws are located behind the primary mirror, at the lower end of the main tube. See Fig. 25. Before adjusting the primary mirror-tilt screws, first unscrew by several turns (use either a hex wrench or pliers) the three hex-head primary mirror lock screws (2, Fig. 25) which are also located on the rear surface of the primary mirror cell and which alter- nate around the cell’s circumference with the three Phillips head screws. Then by trial and error turn the primary mirror Phillips head tilt screws (3, Fig. 25) until you develop a feel for which way to turn each screw to center the reflection of your eye in the drawtube. (An assistant is helpful in this operation.) With your eye centered as shown in Fig. 26, turn the three hex head primary mirror lock screws (2, Fig. 25) to re-lock the tilt-angle of the primary mirror.

The telescope’s optical system is now aligned, or collimated. This collimation should be re- checked from time to time, with small adjustments (per steps 1, 2, and/or 3, above) effected as required to keep the optics well-aligned.

Customer Service hours are 8:30 AM to 4:30 PM, Pacific Time, Monday through Friday. In the unlikely event that your DS-2000 telescope requires factory servicing or repairs, write or call the Meade Customer Service Department first, before returning the telescope to the factory, giving full particulars as to the nature of the problem, as well as your name, address, and day- time telephone number. The great majority of servicing issues can be resolved by telephone, avoiding return of the telescope to the factory.

DS-2000 specifications

The Meade DS-2000 is a versatile and user-friendly telescope that caters to both beginners and seasoned astronomers alike. Known for its exceptional performance and ease of use, the DS-2000 series has become a popular choice among amateur stargazers. This telescope features a robust design coupled with advanced technologies that enhance the overall observing experience.

One of the standout features of the Meade DS-2000 is its sturdy mount, which provides stability during observations. This stability is crucial for clearer and more detailed views of celestial objects, as it minimizes vibrations and shakes that can occur while tracking objects across the night sky. The telescope typically comes with an adjustable aluminum tripod to further enhance stability and can handle varying weights and instruments.

The DS-2000 series utilizes an electronically controlled altazimuth mount, allowing users to easily navigate the sky with its automatic tracking capabilities. This intuitive design ensures that even novice astronomers can locate and follow astronomical objects with minimal effort. The built-in computer control allows users to access a database of thousands of celestial bodies, making it easy to select targets for viewing.

In terms of optics, the Meade DS-2000 features high-quality glass optics with multi-coated lenses. This ensures superior light transmission and contrast, resulting in bright, clear images of the Moon, planets, and deep-sky objects. The telescope typically offers a range of apertures, making it suitable for various observing preferences and conditions.

Furthermore, the Meade DS-2000 is often equipped with a 9mm or 25mm eyepiece, enabling users to achieve magnifications adequate for observing different types of celestial phenomena. The addition of a built-in red-dot finder makes it easier to aim and locate objects in the night sky.

Portability is another significant characteristic of the DS-2000 series. Its lightweight design allows astronomers to transport it easily to different observing locations, making spontaneous stargazing adventures possible, whether in the backyard or at a dark-sky site.

In summary, the Meade DS-2000 combines solid construction, user-friendly features, and advanced technology, making it an excellent choice for anyone interested in exploring the night sky. With its impressive optics, reliable tracking capabilities, and enhanced portability, the DS-2000 series provides an enjoyable and rewarding astronomical experience.
