Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun.

Do not look through the telescope as it is moving.

OBSERVING

Observing by Moving the Telescope 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 tripod base lock knob (26, Fig. 1) and Altitude lock (10F, Fig. 1b),

so that the telescope can move freely.

2. Point your telescope at distant street signs, mountains, trees, and other structures. Use

your red dot viewfinder to help site-in on an object.

3. Centre the object using the red dot viewfinder and then in the telescope eyepiece. When

the object is centred in your eyepiece, re-tighten the base and Altitude locks.

4. Practice focusing objects with the focus knob (1, Fig. 1).

5. Once you get a feel for how your telescope moves and focuses, try to view something more

challenging, like a bird or a distant moving train.

You can also observe stars and objects in the night sky using this method, but note that objects

begin to slowly drift across the eyepiece field. This motion is caused by the rotation of the Earth.

As you become familiar with the Audiostar handbox operation, you can counteract the drift

using the automatic tracking feature in the Audiostar Setup menu (see

TO TRACK AN OBJECT

AUTOMATICALLY, page 16), or by using Audiostar's GO TO capabilities (see GO TO SATURN,

page 19).

Terrestrial Observing

StarNavigator 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 25 mm 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 eyepiece, where the heat waves do not have such an effect on image quality. Observing

in early morning hours, before the ground has built up internal heat, produces better viewing

conditions than during late afternoon hours.

Observing Using Audiostar's Arrow Keys

You may observe land and astronomical objects using Audiostar's Arrow keys to move the

telescope.

1. Tighten the Altitude lock (10F, Fig. 1b) and tripod base lock knob (26, Fig. 1).

2. Make sure the telescope power switch is in the OFF position. Plug Audiostar into the HBX

port of the Control Panel.

3. Flip the telescope power switch to the ON position.

Audiostar is activated and a copyright message displays briefly, followed by a short beep.

Then Audiostar takes a few moments to start up the system.

4. AudioStar displays “Press 0 to align or Mode for Menu.” The telescope motors are now

activated and can be used to move the telescope using the arrow keys.

5. Press the Arrow keys (5, Fig. 2) to slew (move) the telescope up, down, right, or left.

6. Press a NUMBER key (6, Fig. 2) to change the telescope’s slew speed. Each time you

press a number from 1 through 9, the speed will change. See

SLEW SPEEDS, page 15, for

more information.

7. Use the red dot viewfinder (7, Fig. 1 or 1e) to locate an object and practice using the

Audiostar’s Arrow keys to centre the object in the telescope eyepiece's field of view.

8. Use the telescope’s focus knob (1, Fig. 1) to bring the object into focus.

Important Note: When

you look through your

telescope’s eyepiece,

the image might look

strange at first.

If you have a refracting

telescope, objects will

appear right-side-up, but

reversed left-for-right.

This will not make a

difference when

observing astronomical

objects and, in fact, all

astronomical telescopes

present inverted images.

During terrestrial

observing, when a

corrected image (right-

side up and correct left-

for-right) is desirable, an

optional Meade 45°

Erecting Prism is

available. See

OPTIONAL

ACCESSORIES, page 32,

or consult the Meade

Telescope Catalog.

No means of correcting

the image is available for

reflecting telescopes—

the image will appear

upside down and

reversed left-for-right.
