To Add a landmark to the database:

In this procedure, you will store the location of terrestrial landmarks in AutoStar’s memory.

1.Set the telescope in the home position, if necessary. Note for future reference where the telescope is located and if you have aligned the telescope, which alignment method is used.

IMPORTANT NOTE: To use the Landmark function, the telescope must be located and aligned exactly as when the landmark(s) was added to the database.

2.Display the “Setup: Targets” menu option. Choose “Terrestrial” and press ENTER – “Setup: Targets” displays again. Choosing this option turns off tracking for astronomical objects and is not useful for the viewing of terrestrial objects such as those in the Landmark database. Be sure to change this option back to “Astronomical” when you wish to view celestial objects again.

3.Press MODE once. “Select Item: Setup” displays.

4.Press the Scroll Down key once and “Select Item: Object” displays. Press Enter. “Object: Solar System” displays.

5.Press the Scroll Up key twice and “Object: Landmarks” displays. Press ENTER. “Landmark: Select” displays.

6.Press the Scroll Down key once. “Landmark: Add” displays. Press ENTER.

7.“Landmark Name” displays. Using Arrow keys, enter a name for the landmark you wish to add to the database. When finished, press ENTER.

8.“Center Landmark. Press Enter” displays. Using only the Arrow keys (do not manually move the telescope), move the telescope to the desired landmark and center the object in the eyepiece. Press Enter. The object is now stored in memory.

9.“Landmark: Add” displays. If you wish to add more landmarks, repeat steps 5 through 7.

To Select a landmark from the database:

1.Make sure the telescope is located and aligned exactly as when the desired landmark was entered into memory.

2.Display the “Landmark: Select” menu option. Press ENTER.

3.Use the Scroll keys to scroll through the list of objects you have previously entered. When the desired object displays, press ENTER to select the object. Use the Scroll keys to scroll through location information about the object, if desired. Press GO TO to slew the telescope to the landmark.

4.Press MODE to exit.

To perform a Landmark Survey

This procedure allows you to perform a tour of the objects entered in the “Object: Landmark” menu option – note that the Landmark Survey will function only if you have previously entered objects in the Landmark menu.

1.Navigate to “Utilities: Landmark Survey” menu and press ENTER.

2.“Landmark Survey: Slewing...” displays. The telescope moves to the first object on the Survey list and displays the name of the object.

3.Press MODE to pause the Survey. Press Enter to restart the survey at the first object of the survey.

To check on the available amount of memory in AutoStar.

AutoStar has a limited amount of memory. Once you begin to store Landmarks, User Objects and other bits of information in AutoStar, you will begin to use up memory. This procedure allows you to check on how much memory is still available.

1.Navigate to the “Setup: Statistics” menu option and press ENTER.

2.“Statistics: 97.4K Char. Free” displays. This is the amount of memory that is still available to the user.

LT Series, LT ACF Series, LT SC Series specifications

The Meade LT SC Series, LT ACF Series, and LT Series telescopes are designed to meet the diverse needs of amateur astronomers and astrophotographers alike. Each of these series caters to various levels of experience while incorporating advanced features and technologies that enhance observational stability and image quality.

The Meade LT SC Series, featuring the advanced Schmidt-Cassegrain design, excels in versatility. This series includes different aperture sizes, allowing users to view celestial objects ranging from the moon to distant galaxies. The telescopes come equipped with an AudioStar hand controller that provides a database of over 30,000 celestial objects, enabling users to easily locate and track their subjects. The built-in GPS feature facilitates effortless alignment by automatically determining the user’s location and time.

In contrast, the LT ACF Series showcases Meade's innovative Advanced Coma-Free (ACF) optics. This design minimizes coma and field curvature, providing sharp, crisp images across a wider field of view. Ideal for astrophotography, this series is enhanced by features like a fast focal ratio for better imaging of dim objects and a robust construction that ensures stability during use. The LT ACF telescopes also support advanced imaging techniques, allowing users to capture stunning images of deep-sky objects while minimizing aberrations.

The classic LT Series remains a favorite among beginners. Known for its straightforward setup and usability, this series is designed with a lightweight and portable frame. The LT Series telescope is equipped with an altazimuth mount, making it user-friendly for quick observations. The simplicity allows new astronomers to start observing with minimal technical knowledge. Additionally, these telescopes support a variety of accessories such as smartphone adapters, making it easy for users to capture their observations.

All three series incorporate Meade's proprietary StarLock technology in certain models, which facilitates automated tracking. This feature frees astronomers from the complexities of manual tracking, allowing them to focus more on the experience of observing celestial wonders.
