Product description Engineered with a large aperture and fast focal ratio to pierce far into deep space, Meade Instruments' LX600-ACF 12" f/8 Cassegrain GoTo Telescope combines multiple technologies to produce distortion-free high-contrast images with true-color rendition across the entire flat field of view. The scope's performance begins with the aplanatic Advanced Coma-Free (ACF) optical system, which produces a flat field of view with reduced astigmatism and zero diffraction. A low-expansion borosilicate primary mirror further reduces distortion due to temperature fluctuation, and the SCHOTT BOROFLOAT glass corrector plate aligns the light waves to correct spherical and chromatic aberrations. Meade then fully multi-coats all optical surfaces with their proprietary Ultra-High Transmission Coatings (UTHC), which increase light transmission, further improve color fidelity, and boost contrast. For long-exposure astrophotography or long-duration observation sessions, the LX600 boasts a primary mirror lock to completely cancel any residual image shift due to mirror movement.At the core of the LX600 Series' tracking and alignment system is Meade's StarLock technology. StarLock uses both a wide-field and a narrow-field digital camera to identify guide stars as faint as 11th magnitude. Unlike standard autoguidance systems that are controlled by computers, StarLock directly transmits specific real-time commands to each of the servo motors, resulting in maximum accuracy and faster guide corrections to within 1 arcsecond. The optical tube assembly (OTA) is attached to the dual-fork alt-az mount, which uses dual-axis micro motors to find and track objects with virtually zero vibrations. Meade outfitted it with a built-in 16-channel GPS receiver and time chip, so the mount can automatically determine the current date, time, and location within minutes of being turned on. The information is sent to the AutoStar II controller, which uses an electromagnetic sensor to determine True North and can automatically align the scope with minimal user interface. During long observation or exposure imaging sessions, the controller interfaces with the StarLock system to continuously check its orientation and tracking and adjust as needed, sending the data to the Smart Mount and Smart Drive systems. The system learns the tracking errors and adjusts itself for the future.The brain of the mount is Meade's iconic AutoStar II computer controller. This handheld unit has an internal database of over 145,000 objects, from the Moon and planets, to galaxies, nebulae, and constellations. It can calculate future events like sunrises and meteor showers, and predict solar and lunar eclipses for the next 100 years. Once set up and running, the AutoStar II can take you on guided tours of the best objects visible above, including audio tours that can be heard from the internal speaker.The mount and OTA are supported by a sturdy adjustable-height stainless steel tripod that is designed to absorb vibrations for even clearer views. To get you started, Meade includes a 1.25" visual back for the OTA and a 26mm eyepiece that yields 94x magnification. For alignment and manual star-hopping navigation, an 8x50 finderscope and mounting bracket are also included. This finderscope has an illuminated aiming reticle with variable intensity to protect night-adjusted vision. - Optical Tube
