Slew Speeds

Autostar has nine slew speeds that move the optical tube at rates that are directly

proportional to the sidereal rate and have been calculated to accomplish specific

functions. Press the Number key to change the slew speed.

The nine available speeds are:

Number Key 1 = 1x = 1 x sidereal (0.25 arc-min/sec or 0.004°/sec)

Number Key 2 = 2x = 2 x sidereal (0.5 arc-min/sec or 0.008°/sec)

Number Key 3 = 8x = 8 x sidereal (2 arc-min/sec or 0.033°/sec)

Number Key 4 = 16x = 16 x sidereal (4 arc-min/sec or 0.067°/sec)

Number Key 5 = 64x = 64 x sidereal (16 arc-min/sec or 0.27°/sec)

Number Key 6 = 128x = 30 arc-min/sec or 0.5°/sec

Number Key 7 = 1.0° = 60 arc-min/sec or 1.0°/sec

Number Key 8 = 1.5° = 90 arc-min/sec or 1.5°/sec

Number Key 9 = Max = approx. 4.5°/sec

Speeds 1, 2 or 3: Best used for fine centering of an object in the field of view of a

higher power eyepiece, such as a 9mm eyepiece.

Speeds 4, 5 or 6: Enable centering of an object in the field of a low-to-moderate

power eyepiece, such as a 26mm.

Speeds 7 or 8: Best used for rough centering of an object in the viewfinder.

Speed 9: Moves the telescope quickly from one point in the sky to another.

Astronomical Observing

Used as an astronomical instrument, your telescope has many optical and electro-

mechanical capabilities. It is in astronomical applications where the high level of

optical performance is readily visible. The range of observable astronomical objects

is limited only by the observer’s motivation.

Observe the Moon

Point your telescope at the Moon (note that the Moon is not visible every night) and

practice using the Arrow keys and the slew speeds to view different features. The

Moon contains many interesting features, including craters, mountain ranges and fault

lines. The best time to view the Moon is during its crescent or half phase. Sunlight

strikes the Moon at an angle during these periods and adds a depth to the view. No

shadows are seen during a full Moon, making the overly bright surface appear flat and

rather uninteresting. Try using a neutral density Moon filter when observing the Moon

(see

OPTIONAL ACCESSORIES, page 43). Not only does it cut down the Moon's bright

glare, but it also enhances contrast, providing a more dramatic image.

To Track an Object Automatically

As the Earth rotates beneath the night sky, the stars appear to move from East to

West. The speed at which the stars move is called the sidereal rate. You can setup

your telescope to move at the sidereal rate so that it automatically tracks (follows) the

stars and other objects in the night sky. If the telescope is not tracking an

astronomical object, the object will drift out of the eyepiece field of view. The tracking

function automatically keeps an object centered in the telescope’s eyepiece.

To automatically track objects, you need to learn how the Autostar keypad operates

in order to move through its menus. You'll need to initialize and align your telescope.

Moving Through Autostar’s Menus

The Autostar database is organized in levels for quick and easy navigation.

• Press ENTER to go deeper into Autostar's menu levels.

• Press MODE to move back toward the top menu level.

• Press the Scroll keys to move up and down through the options

available for each level.

• Press the Arrow keys to enter characters and digits. The Arrow keys

are also used to move the telescope.
