Inspecting the Optics

A Note About the “Flashlight Test”: If a flashlight or other high-intensity light source is pointed down the main telescope tube, the view (depending upon the observer’s line of sight and the angle of the light) may reveal what appears to be scratches, dark or bright spots, or just generally uneven coatings, giving the appearance of poor quality optics. These effects are only seen when a high intensity light is transmitted through lenses or reflected off the mirrors, and can be seen on any high quality optical system, including giant research telescopes.

The optical quality of a telescope cannot be judged by the “flashlight test;” the true test of optical quality can only be conducted through careful star testing.

Gauging the Movement of the Telescope

A common complaint of many first-time telescope owners is that they cannot see the telescope “move” when the motor drive is engaged. If fact, when the batteries are installed, the power is on, the telescope is moving. However, the movement is at the same speed as the hour hand of a 24-hour clock; as such, the movement is difficult to discern visually.

To check the movement of your telescope, look at an astronomical object through the telescope’s eyepiece with the telescope polar aligned and with the motor drive on. If the object remains stationary in the field of view, your telescope is operating properly. If not, check to ensure that “Astronomical” is selected in the “Targets” option of the setup menu.

Updating Your LT Series Firmware

Meade is constantly refining and improving the operating firmware that controls our computerized telescopes and we even add new features and capabilities from time to time. Your new LT Series shipped with the most current firmware at the time of manufacture, but there may well be a new version available through the AutoStar Updated program supplied on the AutoStar Suite DVD supplied with your telescope. The Updater goes online to the Meade web site and checks to see if there is a newer version available and can download it directly to the telescope using the #505 Cable Connector Kit. See the instruction sheet included with the kit for more information.

CUSTOMER

SERVICE

If you have a question concerning your LT Series telescope, call the Meade Instruments Customer Service Department at (800) 626-3233. Customer Service hours are 7:00 AM to 5:00 PM, Pacific Time, Monday through Friday. In the unlikely event that the LT Series requires factory servicing or repairs, before returning the telescope to the factory, write or call the Meade Customer Service Department to provide an explanation of the problem, as well as your name, address and daytime telephone number. The great majority of servicing issues can be resolved by telephone, avoiding return of the telescope to the factory.

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.

In summary, the Meade LT SC Series, LT ACF Series, and LT Series deliver exceptional optical performance and user-friendly features, making them suitable for a wide range of astronomy enthusiasts. Whether you are a seasoned astrophotographer or a novice sky-watcher, Meade's telescopes provide the technology and capabilities needed to explore the universe.
