Meade LX200-ACF overview

  • 1Description

Designed and built for near-research-grade work, the Meade Instruments LX200-ACF 305mm f/10 Catadioptric GoTo Telescope represents one of the largest apertures in the series to yield bright and clear views with the capability to reach far into deep space. Outfitted with a large 305mm (12") oversized primary mirror, the optical path is made in Meade's proprietary Advanced Coma-Free (ACF) hybrid catadioptric lens/mirror/corrector plate configuration, with their Ultra-High Transmission Coating (UHTC) system. The ACF and UHTC work together, along with the large light bucket and long focal length, to produce images with virtually zero distortion, off-axis coma, fringing, astigmatism, or other aberration across the entire field of view and with accurate high-contrast colors.

Controlling the mount and focuser is the AutoStar II controller. This full-featured GoTo system has a database of over 145,000 objects with multiple custom guided tours—including audio tours via its built-in speaker. Complete with variable slew and tracking rates, plus autoguider compatibility, the AutoStar helps to unlock the true potential of the optical tube assembly (OTA). Its dual-tine motorized fork mount is outfitted with a 16-channel GPS receiver that transmits accurate day, time, and location to the AutoStar hand controller, and True Level and True North sensors assist in accurate setup for more precise alignment as well as GoTo and tracking accuracy. Meade offers the LX200 here with just the OTA and mount, for users who already have a heavy-duty tripod or a permanent pier to support the 75-pound weight. Meade makes the LX200 ready to go out of the box by including a 1.25" 90° star diagonal, a moderate-magnification eyepiece, and a large 8x50 finder with quick release bracket.

Optical Tube Assembly
  • Large 305mm (12") aperture draws in enough light for observing deep-sky objects
  • Moderate f/10 focal ratio makes the OTA ideal for long-exposure astrophotography when mount/OTA is used with an equatorial wedge
  • Long 3048mm focal length produces a high magnification potential to perform deep-sky observations easily
  • Advanced Coma-Free catadioptric design
  • Ultra-High Transmission Coatings (UHTC) system
  • Resolution: 0.380 arcsec, Dawes' Limit
  • Internal mirror lock prevents focus adjustments for long-exposure astrophotography
  • Internal single-speed coarse focuser complements the included zero image-shift electronic focuser
  • 1.25" standard SCT visual back accepts the most common size eyepieces and accessories
Optical Technologies
Advanced Coma-Free System:
  • Reduces off-axis comas and astigmatism for sharper images
  • Eliminates diffraction spikes for better resolution
  • Aplanatic design produces flat, distortion-free images across the field of view—especially at the edges
Ultra-High Transmission Coatings (UHTC):
  • All corrector plate and mirror surfaces are fully multi-coated
  • Engineered to optimize visual, photographic, and CCD imaging
  • Improves light transmission across the entire visible spectrum through the optical path
  • Corrector plate coatings made up of multiple layers of aluminum oxide (Al2O3), titanium dioxide (TiO2), and magnesium fluoride (MgF2)
  • Mirror coatings consist of aluminum with multi-layer coatings of titanium dioxide (TiO2) and silicon dioxide (SiO2)


AutoStar II GoTo Computer Controller
  • Full GoTo capabilities
  • Intuitive menu-driven interface
  • 145,000 object database
  • Multiple guided tours available based on when and where it is set up
  • Guided audio tours via built-in speaker
  • Tracking accuracy: ±1 arcsec
  • Smart Drive system for Periodic Error Correction (PEC) and Permanent Periodic Error Correction (PPEC): Trains out tracking errors for more precision
  • Tracking rates: Sidereal, lunar, custom: Select from 2000 incremental rates
  • Multiple slew speeds: 1x, 2x, 8x, 16x, 64x sidereal, 0.25°/sec, 0.5°/sec, 1°/sec, 2°/sec (max)
  • Fast slew speeds from 1 to 8°/sec, user selected at 0.1°/sec increments; fine slewing and photographic guiding speed from .01x to 1x sidereal in one one-hundredth increments
  • Calculate future dates and times for events like sunrises and sunsets; moonrises, moonsets, and Moon phases; solar and lunar eclipses for the next 100 years; meteor showers; and equinoxes and solstices
  • Flash updatable via the Meade website
Database details:
  • Solar system: Sun, Moon, asteroids, comets
  • Moon features including landing points, mountains, craters, and lakes
  • Satellites: Including the International Space Station, the Hubble Space Telescope, GPS satellites, and geosynchronous orbit satellites

  • Mount only; heavy-duty tripod or permanent pier required for proper use; EQ wedge required for long-exposure astrophotography to avoid field rotation
  • Heavy-duty double-tine alt-azimuth fork mount
  • Dual-axis mechanical locks and slow-motion dials for manual use without power
  • Smart Mount system automatically detects, calculates, and corrects any systematic pointing errors, regardless of the cause; set through the AutoStar controller
  • 16-channel GPS receiver accurately transmits viewing day, time, and location to hand controller for faster setup and alignment
  • True Level and True North Sensors (LNT) assist in accurate setup for more precise alignment as well as GoTo and tracking accuracy
  • Integrated time chip maintains current time, even when powered down, for faster setup time
