Smart Drive provides permanent periodic error correction (PPEC) on both axes by learning and averaging error over the course of one or more training periods, thereby minimizing guiding corrections during long-exposure photographs.Precisely defined, coma is a distortion in which the image of a star cannot be focused to a point, but takes on the shape of a comet. Coma Killer - What is coma? It's not some sort of astronomical state of unconsciousness.

Compatible with both equatorial and altazimuth mounts. Smart Mount constantly refines pointing accuracy each time an object is centered and updated.This additional 1/4" yields a wide, fully illuminated field-of-view. Oversize Primary Mirror diameters are greater than their listed aperture (e.g., the diameter of the 8" LX200-ACF is actually 8.25").Primary Mirror Lock locks the mirror in place during long-exposure astrophotography.Objects such as stars, galaxies, and nebulae will appear significantly brighter. Meade Ultra-High Transmission Coatings (UHTC) increases total light transmission and image brightness by nearly 20% over Meade's standard coatings.The LX200-ACF is the perfect platform for the demanding researcher and imaging enthusiast. Meade's Advanced Coma-Free system also reduces astigmatism and eliminates diffraction spikes found in classical RCs.

f/10 Advanced Coma-Free Optics: Building from a classic RC design, Meade has created a new design with the same coma-free pinpoint star images and flatter field that discerning astrophotographers and most professional observatories have come to expect from classic Ritchey Chretien optics.Meade 12" f/10 LX200-ACF Advanced Coma-Free Telescope Features The design even eliminates diffraction spikes and improves astigmatism, both of which are inherent in the traditional RC design. This ACF design produces a coma-free, flat field of view that rivals traditional RC telescopes at a fraction of the cost.

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. Because the mirrors in these telescopes have always been very expensive to make, few amateur astronomers could enjoy them. RC telescopes (from a variety of manufacturers) are found in most of the world's top observatories and NASA's Hubble Space Telescope.

It's the biggest news in astronomy since, well, the LX200.Ī traditional RC design is a type of reflector that delivers a coma-free, flat field of view via hyperbolic primary and secondary mirrors. The Meade LX200-ACF telescope includes all the field-proven features of the LX200 including GPS, Primary Mirror Lock, Oversized Primary Mirror, SmartDrive Smart Mount, AutoStar II and more. Now you can own similar optics to what the professionals use. 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. Meade's LX200-ACF brings Advanced Coma-Free (ACF) optics within reach of aspiring astronomers everywhere. The most widely used research telescope on earth now comes with the most advanced optical system.
