1.25" Eyepiece Holder

Thumb Screw

Eyepiece: Place the Super Plössl 26mm eyepiece into the 90° diagonal prism (Pg. 13, Fig. 1, 2) and tighten in place with the thumbscrews. The eyepiece magnifies the image collected in the optical tube.

Diagonal Thumbscrew: Tightens the eyepiece in place. Tighten to a firm feel only.

Optical Tube Assembly (OTA): The main optical component that gathers the light from distant objects and brings this light to a focus for examination through the eyepiece.

Single Fork Arm Mount: Holds the optical tube in place and moves it to find and track objects.

Focus Knob: Moves the telescope’s primary mirror in a finely-controlled motion to achieve precise image focus. The LT Series telescope can be focused on objects from a distance of about 25 ft. to infinity. Rotate the focus knob counterclockwise to focus on distant objects, and clockwise to focus on nearby objects.

Computer Control Panel

A. Handbox (HBX) Port: Plug the AutoStar coil cord (Pg 19, Fig. 5, 10) into this port.

B.LED: The red power indicator light illuminates when power is applied to the telescope.

C.ON/OFF Switch: Turns the Computer Control Panel and AutoStar ON or OFF

D.Auxiliary (AUX) Port (2): Provides connection for Meade accessories. See OPTIONAL ACCESSORIES, page 16.

E.12v Power Connector: Provides connection so that the telescope assembly may be powered from either a 12v DC auto cigarette light plug or from a standard 115v AC home outlet.

Dust Cover: Gently lift out the dust cover from the front lens of the telescope. The dust cover should be replaced after each observing session and the power turned off to the telescope. Verify that any dew that might have collected during the observing session has evaporated prior to replacing the dust cover.

Battery Compartment: Insert eight ANSI 14A (IEC LR14) Alkaline “C-Cell” (user-supplied) batteries in compartment. Be sure batteries are aligned correctly as shown in the battery compartment.

Red Dot Finder: Provides an easy way to sight on objects and put them in the telescope’s eyepiece.

Red Dot Finder Alignment Screws: Adjust these screws to align the Red Dot Finder with the telescope’s main optics. See page 8 for more information.

Handbox Storage Cradle: Holds the AutoStar handbox in a convenient position on the telescope.

AutoStar Suite Software: Contains the LT Series Instruction Manual and a collection of useful software including a planetarium program, the AutoStar Updater for downloading and upgrading the firmware in the telescope, software to control the telescope from a computer and other programs all designed to enhance your use of the LT Series system.

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.
