Slew Speeds

AutoStar has nine slew speeds that are directly proportional to the sidereal rate (this is the speed at which stars move) and have been calculated to accomplish specific functions. Pressing the SPEED/? key changes the slew speed, which is then shown for about two sec- onds on AutoStar’s display.

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 12mm or a 9mm eyepiece.

Speeds 4, 5, or 6: Enables centering an object in the field of a low-to-moderate power eye- piece, such as a standard 25mm eyepiece.

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

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

DS-2000 TIPS

Which One’s the

Alignment Star?

If Autostar has chosen an alignment star with which you are unfamiliar, how can you be sure if the star in your eyepiece is really the alignment star?

The rule of thumb is that an alignment star is usually the brightest star in that area of the sky. When you view an alignment star in an eyepiece, it stands out dramatically from the rest of the stars in that portion of the sky.

If you have an obstruction, such as a tree or a building blocking your view of the alignment star, or if you have any doubts at all about the star that has been chosen, no problem. Just press the Scroll Down key and Autostar will find another star to align upon.

The combination of high-quality glass optics and a fully coated lens system ensures excellent light transmission, making it ideal for viewing planets, star clusters, and other astronomical phenomena.

One of the standout features of the DS-2102AT-TC is its AutoStar technology. This advanced computer-controlled system provides users with the ability to easily locate and track thousands of celestial objects. With a simple press of a button, the telescope automatically aligns itself to the night sky, allowing for hassle-free observation. This feature is particularly beneficial for beginners who may find it challenging to manually locate specific stars or planets.

The DS-2090AT-TC model incorporates a slightly different design, featuring a larger 90mm aperture and a similar refractor configuration. This telescope is also equipped with the AutoStar computer control system, enhancing the user experience by offering guided tours of the night sky. The DS-2090AT-TC excels in delivering bright and detailed views of deep-sky objects, making it a great option for those interested in exploring the wonders of the universe.

Both models are designed for portability, making them easy to transport to various observation sites. The sturdy mount and adjustable tripod provide stability and ease of use, ensuring that users can enjoy extended viewing sessions without fatigue. Additionally, these telescopes come with a variety of eyepieces, allowing for different magnification levels to suit the observer's preference.

In conclusion, the Meade DS-2102AT-TC and DS-2090AT-TC offer a compelling combination of advanced technology, user-friendly features, and high-quality optics. Whether you're a beginner eager to explore the night sky or a seasoned enthusiast seeking detailed celestial observations, these telescopes provide the tools you need to immerse yourself in the wonders of astronomy.
