![]() Turn the lock knob located just above the telescope's main focus knob and the progressive-tension primary lock completely cancels any residual image shift due to mirror movement during visual or imaging applications. First is the inclusion of a focus lock system, which prevents the mirror from moving while observing or during long exposure astrophotography as the telescope tracks across the sky. The Meade LX200 series differs from the LX90 offerings in several key ways. ![]() The optical path and components of the ACF telescope design Key Features and Upgrades in the LX200 Series ![]() Meade ACF telescopes, including the mounts, are manufactured and assembled in North America. The ACF primary, secondary and corrector plate glass blanks are manufactured in the USA exclusively for Meade. The ACF system also reduces astigmatism and eliminates diffraction spikes.ĭesigned and Manufactured in North America. The Ultra-High Transmission Coatings (UHTC) are included as with all Meade ACF optics, yielding maximum image brightness and contrast at the eyepiece or camera sensor. This makes the ACF system ideal for visual observers and astro-imagers alike. The patented Advanced Coma Free (ACF) optics produce impressively flat fields of view with no coma, even out to the edges of larger format cameras or extreme wide angle eyepieces. Push button controls, automatic locating and tracking of celestial objects, and a wealth of object data at your fingertips in the AutoStar II hand controller make the LX200 a joy to use. Strong and stable fork arms hold the optical tube rock solid to dampen any vibrations, which is critical for high power planetary observation or long exposure deep-sky imaging. When disassembled, the LX200 8" is easily manageable by one person and can be set up quickly with a minimum of effort. Incredibly compact for its aperture, the 8" f/10 ACF is ideally suited for setting up in the backyard, both small/medium sized observatories, and taking in the car to a dark sky site on the weekend. The Meade 8" f/10 LX200 ACF Telescope has long been a classic fixture among Meade's LX series of Alt/Az fork mounted telescopes. ![]()
