Brightness Adj: Adjusts the brightness of the display using the Scroll keys. When complete, press

ENTER.

Contrast Adj: Adjusts the contrast of the display using the Scroll keys. When complete, press

ENTER.

NOTE: This feature is usually only required in very cold weather.

Landmark Survey automatically slews the telescope to all user-defined landmarks with a short pause at each location. Press ENTER to start the survey. While a slew is in progress, press any key to skip that object and go to the next landmark on the list. To observe a landmark for a longer period, press MODE when paused on the object to stop the survey. Press ENTER to restart the survey at the first object on the list. See "Landmark," page 16.

Sleep Scope is a power saving option that shuts down Autostar and the telescope without for- getting its alignment. With "Sleep Scope" selected, press ENTER to activate the Sleep func- tion. Autostar goes dark, but the internal clock keeps running. Press any key, except ENTER, to re-activate Autostar and the telescope.

Park Scope is designed for a telescope that is not moved between observing sessions. Align the telescope one time, then use this function to park the telescope. Next time it is powered up, enter the correct date and time - no alignment is required. Pressing ENTER causes the tele- scope to move to its pre-determined Park position. Once parked, the screen prompts to turn off power.

IMPORTANT NOTE: When the "Park Scope" option is chosen and the display prompts you to turn off the telescope's power, Autostar is unable to be returned to operation without turning the power off and then back on.

Setup Menu

The Setup menu’s primary function is to align the telescope (see pages 14 and 21). However, there are numerous other features available within the Setup menu, including:

Date changes the date used by Autostar. This function is useful to check events in the past or future. For example, set the Date menu for a day three months in the future. Then check the

"Select Item: Event" menu for the Sunset

 

time on that date. See “EVENT MENU,”

TIPS FOR BEGINNERS

page 17.

Time changes the time entered into Autostar. Setting the correct time is criti- cal for Autostar to properly calculate locations and events. Time may be set to 24-hour mode (military time) by selecting the "blank" option which follows the "AM" and "PM" options.

Daylight Saving is used to enable or disable Daylight Savings time.

NOTE: Daylight Savings Time may be referred to by different names in various areas of the world. Check local time to verify.

Telescope accesses the several options, including:

Telescope Model: Selects the model of telescope connected to Autostar.

Focal Length: Displays the focal length of the selected telescope.

Az Ratio and Alt Ratio: The Az (Azimuth) ratio and Alt (Altitude) ratio refers to the gears of the tele- scope's motors. Do not alter these numbers.

Mount: Choose between Alt/Az mount or Polar Mount. Mount requires that the telescope be physically aligned to the mount selected in this menu. The default setting is "Alt/Az."

Surf the Web

One of the most exciting resources for astronomy is the internet. The internet is full of websites with new images, discoveries, and the latest astronomical information. For example, when comet Hale-Bopp made its approach to our Sun in 1998, astronomers around the world posted new photos daily.

You can find websites for almost any topic relating to astronomy on the internet. Try the following key word searches: NASA, Hubble, HST, astronomy, Messier, satellite, nebula, black hole, variable stars, etc.

Check out Meade’s website for the latest product and technical information. You can download the latest software revisions, links to other astronomi- cal sites, coordinates of celestial objects and the latest satellite tracking information for your #494 Autostar handset.

ETX-70AT specifications

The Meade ETX-70AT is a compact, portable telescope that caters to both amateur astronomers and educational purposes. This telescope is part of the renowned ETX series, known for its innovative features and user-friendly design. With an aperture of 70mm, the ETX-70AT is designed to provide clear, bright images of celestial objects, making it an ideal choice for novice astronomers eager to explore the night sky.

One of the standout features of the ETX-70AT is its Maksutov-Cassegrain optical design. This design combines a Maksutov corrector plate with a compact cassegrain layout, allowing for a shorter tube length while still providing excellent optical performance. As a result, users can easily transport the telescope to various observing locations without compromising on image quality.

The telescope boasts a focal length of 350mm, which offers a wide field of view, allowing observers to comfortably locate and track celestial phenomena. The ETX-70AT comes equipped with a built-in electronic control system known as the Audio Star, featuring a database of over 30,000 celestial objects. This system not only makes it easier for users to locate specific targets but also enhances the overall observing experience by providing informative audio commentary about different astronomical objects.

Another notable characteristic is its lightweight design, weighing in at just around 5 lbs. This portability factor makes it an excellent choice for stargazers who prefer to travel or hike to optimal viewing locations. The telescope is mounted on an adjustable and stable aluminum tripods, providing a solid foundation for viewing.

The Meade ETX-70AT also includes a variety of accessories, including two eyepieces (26mm and 9.7mm), a finder scope to help users aim accurately, and a variety of optional filters to enhance viewing contrast and clarity. Furthermore, the telescope supports direct connection to a computer for astrophotography, enabling enthusiasts to capture their astronomical observations digitally.

In summary, the Meade ETX-70AT is an exceptional entry-level telescope that combines portability, advanced technology, and ease of use. With its powerful optics, automated features, and impressive accessory offerings, it serves as an excellent tool for any individual or educational institution looking to delve into the wonders of astronomy.
