Terrestrial Observing

The LS is an excellent high-resolution, terrestrial (land) telescopes. Viewing terrestrial objects requires looking along the Earth’s surface through heat waves. These heat waves often cause degradation of image quality. Lower power eyepieces, like the Super Plössl 26mm eyepiece, magnify these heat waves less than higher power eyepieces. Therefore, lower power eyepieces provide a steadier, higher quality image. If the image is fuzzy or ill-defined, reduce to a lower power eyepiece, where the heat waves do not have such an effect on image quality. Observing in early morning hours, before the ground has built up internal heat, produces better viewing conditions than during late afternoon hours.

If you wish to observe a distant land object, such as a mountain top or a bird, you want to use your telescope in its Terrestrial Observing mode. To start up the telescope in Terrestrial mode:

1.Turn on the telescope.

2.When you hear the introductory audio, press the “MODE” key. The telescope will move to the home position, and when it has stopped “Select Item” will show on the Handbox screen. Use the SCROLL keys to move through the menu to “Align”. Press the “ENTER” key again to set- up the “Align” menu. Use the SCROLL keys to move to “Terrestrial” and hit “ENTER”.

3.Move your telescope using the direction arrows on the handbox while looking through the Red- Dot Finder to put your target in the eyepiece.

4.Focus on the target with the focus knob (pg. 12,

Fig. 2, 9).

LS TIPS

Too Much Power?

Can you ever have too much power? If the type of power you’re referring to is eyepiece magnification, yes, you can! The most common mistake of the beginning observer is to “overpower” a telescope by using high magnifications which the telescope’s aperture and atmospheric conditions cannot reasonably support. Keep in mind that a smaller, but bright and well-resolved image is far superior to one that is larger, but dim and poorly resolved (see Figs. 7a and 7b to the left). Powers above 400X should be employed only under the steadiest atmospheric conditions.

Most observers should have three or four additional eyepieces to achieve the full range of reasonable magnifications possible with the LS telescopes. See OPTIONAL ACCESSORIES, page 16.

6" LS-6 SC, 8" LS-8 ACF, 6" LS-6 ACF, 8" LS-8 SC specifications

The Meade 8" LS-8 SC, 6" LS-6 ACF, 8" LS-8 ACF, and 6" LS-6 SC telescopes represent cutting-edge advancements in amateur astronomy, catering to both novice stargazers and seasoned astronomers alike. Each model incorporates innovative technologies, making it easier than ever to explore the cosmos.

The Meade 8" LS-8 SC (Schmidt-Cassegrain) features a compact design with an 8-inch aperture that provides exceptional light-gathering capabilities. This telescope utilizes an advanced computer-controlled system known as the AutoStar II. This technology allows for hassle-free navigation across the night sky. The LS-8 SC comes equipped with a built-in observatory, ensuring a user-friendly experience, allowing beginners to locate and track celestial objects with ease. The telescope's premium optics guarantee sharp, high-contrast images, making it an ideal choice for planetary and deep-sky observation.

Next, the Meade 6" LS-6 ACF (Advanced Coma-Free) delivers superior optical performance with minimal distortion. This design eliminates spherical aberrations, providing exceptionally sharp images across the entire field of view. Featuring a 6-inch aperture, the LS-6 ACF is highly portable and perfect for both visual observations and astrophotography. It includes the AutoStar computer system for easy alignment and tracking, as well as a robust, sturdy mount that enhances stability during viewing sessions.

The 8" LS-8 ACF builds on the strengths of its predecessors with an even larger aperture, ensuring maximum light-gathering potential for serious observers. The improved ACF optics yield crisp images without the common off-axis distortions seen in traditional designs. This telescope is also equipped with hassle-free setup features, allowing users to spend more time observing and less time setting up. The OTA design and mount are tailored for easy transport, making it a favorite for astrophotographers seeking high-quality celestial imagery.

Finally, the Meade 6" LS-6 SC offers a balanced option for those seeking portability without sacrificing optical quality. Like its larger counterpart, the LS-6 SC is designed for ease of use and includes the AutoStar technology for automated tracking. Its compact design and lightweight build make it convenient for travel, while still providing an impressive 6-inch aperture for celestial viewing.

In summary, the Meade 8" LS-8 SC, 6" LS-6 ACF, 8" LS-8 ACF, and 6" LS-6 SC telescopes exemplify the intersection of portability, usability, and advanced optics. Each telescope supports astronomers of all skill levels, making the wonders of the universe accessible to everyone. Whether you're observing planets, nebulae, or star clusters, Meade’s innovative technologies enhance the overall experience, ensuring that the night sky is within reach.
