OPTIONAL ACCESSORIES

Meade makes a complete line of accessories to enable you to get the most fun and performance from your LT Series telescope. No matter what you want to accomplish, we have the equipment to help you get there.

Choosing Eyepieces

A telescope’s eyepiece magnifies the image formed by the telescope’s main optics. Each eyepiece has a focal length, expressed in millimeters, or “mm.” The smaller the focal length, the higher the magnification. For example, an eyepiece with a focal length of 9mm has a higher magnification than an eyepiece with a focal length of 26mm. Experienced users know that higher powers are, in general, not as useful as lower powers. Many of the objects in the night sky are relatively large and faint and look best at low magnifications.

The power or magnification of a telescope is determined by the focal length of the telescope and the focal length of the eyepiece being used. To calculate magnification, divide the telescope’s focal length by the eyepiece’s focal length. For example, a 26mm eyepiece is supplied with the LT Series. The focal length of the 6" LT Series is 1524mm (see SPECIFICATIONS, page 47).

Telescope Focal Length 1524mm

Eyepiece Focal Length 26mm

1524 ÷ 26 = 58.6x

The magnification is therefore 58.6x.

Low power eyepieces offer a wider field of view, bright, high-contrast images, and long eye relief. To find an object with a telescope, always start with a lower power eyepiece such as the Super Plössl 26mm or longer focal length. When the object is located and centered in the eyepiece, you may wish to switch to a higher power eyepiece to enlarge the image as much as practical for prevailing seeing conditions or, for many objects, the view is best with a high quality low-power wide-field eyepiece.

NOTE: Seeing conditions vary widely from night-to- night and site-to-site. Turbulence in the air, even on an apparently clear night, can distort images. If an image appears fuzzy and ill-defined, reduce to a lower power eyepiece.

Your telescope comes supplied with a Super Plössl

26mm eyepiece, which gives a wide 53 ARC Minute (just a little less than 1 degree) field of view with 59x magnification. This is a very good all purpose eyepiece for your telescope, but you should consider buying additional eyepieces in longer and shorter focal lengths to fully realize the potential of the excellent 6" optical system in your LT Series telescope.

The Series 4000 Super Plössl Eyepieces are excellent well corrected 4 element optics at popular prices. They come in a wide range of focal lengths to give you the right magnification for any type of celestial object you are viewing. You can also use one of the Series 4000 Barlows to double or triple the magnification of a Super Plössl eyepiece. These eyepieces have been the standard for over 30 years.

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.
