TIP:

Entering R.A. and Dec. Coordinates of an object without using the menus:

If you do not wish to navigate through the menus, a more direct way to enter coordi- nates is to press and hold MODE for two seconds or more. R.A. and Dec. coordinates display. Press GO TO. "Object Position" and a set of coordinates displays. Enter the R.A. and Dec. coordi- nates of any celestial object using the Up and Down Arrow keys, overwriting the coordi- nates currently dis- played. As soon as the coordinates are entered, Autostar slews the telescope to the coordinates. Note that the telescope must be initialized and placed in the Alt/Az home position (see page 17) for this procedure to operate properly.

However, if you wish to store the coordi- nates of an object in memory, use the method described at the right.

APPENDIX B

Using Autostar 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. Autostar provides a feature that allows you to enter an object's R.A and Dec. coordinates in the "User: Objects" option of the Object menu and allows automatic slewing of the telescope to the user-entered coordinates.

In order to use this menu option, you first need to look up the R.A and Dec. coordinates of the object or objects you wish to observe. Check out your local library, computer store, bookstore, CD Roms, Internet, or magazines (such as Sky & Telescope or Astronomy), to find coordinates of celestial objects. The objects/coordinates you enter become part of your own permanent database, called "User Objects."

To enter coordinates of an object into the "User: Objects" option of the Object menu:

1.Make sure Autostar has been initialized and the telescope has been aligned.

2.After the telescope is aligned, "Select Item: Object" displays. (If necessary, use the Scroll keys to scroll through the menus, as previously described, to find this option.) Press

ENTER.

3."Object: Solar System" displays. Keep pressing the Scroll Up key until "Object: User Object" displays and press ENTER.

4."User Object: Select" displays. Press the Scroll Down key once. "User Object: Add" dis- plays. Press ENTER.

5."Name" displays on the top line and a blinking cursor on the second line. Use the Arrow keys, as previously described, to enter the name of the object you wish to add to the data- base. When you are finished, press ENTER.

6."Right Asc.: 00.00.0" displays. Use the Up and Down Arrow keys to enter the digits for the Right Ascension coordinate of your object. When you are finished, press ENTER.

7."Declination: +00°.00'" displays. Use the Up and Down Arrow keys to enter the digits for the Declination coordinate of your object. If necessary, use the Scroll Keys to change "+" to "-." When you are finished, press ENTER.

8.Autostar then prompts you to enter the size of the object. This step is optional. Use the Up and Down Arrow keys to enter the size (in arc-minutes), if so desired, and press ENTER to go to the next display. If you do not wish to enter this information, simply press ENTER.

9.Autostar then prompts you to enter the magnitude of the object. This step is also optional. Use the Up and Down Arrow keys to enter this information, if so desired, and press ENTER to go to the next display. "User Object: Add" displays again.

To GO TO a user-entered object:

In this procedure, you will choose an object from the User Object list and GO TO the object.

1.With "User Object: Add" displayed, press the Scroll Up key once. "User Object: Select" dis- plays. Press ENTER.

2.Use the Scroll keys (if necessary) to scroll to the desired object. Press ENTER.

3.The name of the object and the Right Ascension and Declination coordinates display.

4.Press GO TO and the telescope slews to the object.

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.
