Instruction Manual

12. Using the Arrow keys, scroll to „Site: Select.“ The site you have just edited

displays. Press ENTER to select the site or press MODE to exit.

Finding objects not listed in the libraries

In this procedure, you will enter coordinates of celestial objects that do not

appear in any of the handbox libraries. You will enter the object‘s name and R.A.

and Dec. coordinates (required information). You may also enter the object‘s

magnitude and size (optional information).

Although the handbox contains an extensive database of celestial objects (stars,

nebulae, planets, etc.) that you can observe, you may eventually want to view

objects that are not part of a library. The handbox 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, or bookstore for astronomy books, CD Roms, or maga-

zines (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 the handbox 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“ displays. 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 database. When you are finished, press ENTER.

6. „Right Asc.: 00.00.0“ displays. Use the Number 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 Number 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. The handbox then prompts you to enter the size of the object. This step

is optional. Use the Number 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. The handbox then prompts you to enter the magnitude of the object. This

step is also optional. Use the Number 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“ displays. 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.

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. coordi-

nates display. Press GO TO.

„Object Position“ and a set

of coordinates displays. Enter

the R.A. and Dec. coordinates

of any celestial object using

Number keys, overwriting

the coordinates currently

displayed. As soon as the

coordinates are entered, the

handbox slews the telescope

to the coordinates. Note that

the telescope must be initial-

ized (see page 16), placed in

the Home position (see page

14), and aligned (see page 18)

for this procedure to operate

properly.

However, if you wish to store

the coordinates of an object

in memory, use the method

described at the right.
