Meade's LX200-ACF brings Advanced Coma-Free (ACF) optics within reach of aspiring astronomers everywhere. Nearly every observatory reflector in the world uses an aplanatic (coma-free) optical system like the Ritchey-Chretien (RC), including NASA's Hubble Space Telescope. Now you can own similar optics to what the professionals use.
The LX200-ACF includes all the field-proven features of the LX200 including GPS, Primary Mirror Lock, Oversized Primary Mirror, SmartDrive, Smart Mount, AutoStar II and more. Plus, the LX200-ACF comes with observatory-class optics and a Series 4000 26mm Plössl eyepiece. The LX200-ACF. It's the biggest news in astronomy since, well, the LX200.
This 14" LX200-ACF has 14" diameter f/10 ACF optics (focal length 3556mm) and Ultra-High Transmission Coatings (UHTC) for maximum image brightness and contrast. Features the advanced LX200 AutoStar II computer system with 145,000 object library, multiple guided tours, High Precision Pointing capability with sub arc-minute pointing accuracy, and Meade SmartDrive with Permanent Periodic Error Correction.
The "advanced" in Advanced Coma-Free.
A traditional Ritchey-Chretien (RC) is a type of reflector that delivers a coma-free, flat field of view via hyperbolic primary and secondary mirrors. RC telescopes (from a variety of manufacturers) are found in most of the world's top observatories and NASA's Hubble Space Telescope. Because the mirrors in these telescopes have always been very expensive to make, few amateur astronomers could enjoy them. Fortunately, Meade engineers developed a radical new Advanced Coma Free design by combining a hyperbolic secondary mirror with a corrector-lens-and-spherical-primary-mirror combination that performs as one hyperbolic element. This ACF design produces a coma-free, flat field of view that rivals traditional RC telescopes at a fraction of the cost. The design even eliminates diffraction spikes and improves astigmatism, both of which are inherent in the traditional RC design. When reviewing Meade's LX400-ACF Advanced Coma Free, Sky and Telescope magazine said, " It does indeed perform like a Ritchey-Chretien. The difference between the off-axis images (compared to a Schmidt-Cassegrain) was dramatic to say the least."
Meade UHTC is a series of exotic optical coatings precisely tuned to optimize the optical performance of your LX telescope. Image brightness is increased by nearly 15% over standard coatings. Objects such as stars, galaxies and nebulae as observed through your LX will be dramatically brighter. Even observations of the Moon and planets will benefit in increased image brightness from the full spectrum of light transmission.
AutoStar II controller features "Hot Keys" for quick access to a 145,000 celestial object database. AutoStar II can be updated with the latest software upgrades, guided tours and timely objects like comets free at meade.com.
