Outline
The new Meade LX200-ACF catadioptric telescope has Advanced Coma-Free optics to bring the astronomical image quality of a professional observatory to you at an amazing price. It has a flat, coma-free field similar to that of the Ritchey-Chrétien reflector optics used in most professional observatory telescopes and the Hubble Space Telescope, but at a fraction the cost!

Astronomy Now says "the optics are superior to traditional Schmidt Cassegrains and the new instrument excels and is a clear winner" Meade LX200ACF Advanced Optical Tubes offer superb optics in a portable package and are available to attach to your choice of mounting.

The LX200ACF includes all the field-proven features of the LX200 including Primary Mirror Lock, Oversized primary mirror, Plus the LX200ACF comes with observatory-class optics crafted in Irvine California, Tubes are supplied without accessories but the 8" and 10" versions do have a universal flat mounting bar running along the base of the tube as standard. We can supply mounting hardware for the 12" and 14" models to suit most equatorial mounts including Losmandy.

Reviewed recently in Astronomy Now Magazine concluding that "the optics are superior to traditional Schmidt Cassegrains and the new instrument excels and is a clear winner".

Advanced Coma-Free optics
Meade’s (Advanced Coma-Free™) optics deliver stunning Ritchey-Chretien performance at a Schmidt Cassegrain price.

The "advanced" in Advanced Coma-Free
A traditional Ritchey-Chrétien (RC) is a type of reflector that delivers a coma-free, flat field of view via hyperbolic primary and secondary mirrors. 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-Chrétien]. The difference between the off-axis images (compared to a Schmidt-Cassegrain) was dramatic to say the least.”

Coma Killer
What is coma? It’s not some sort of astronomical state of unconsciousness. It’s an optical aberration. 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.

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 also reduces the astigmatism and eliminates diffractions spikes found in classical RCs. The LX200-ACF is the perfect platform for the demanding researcher and imaging enthusiast with telescopes available in apertures of 8 inches, 10 inches, 12 inches, 14 inches, and 16 inches.

Meade Ultra-High Transmission Coatings (UHTC™)
Increases total light transmission and image brightness by nearly 20% over Meade’s standard coatings. Objects such as stars, galaxies and nebulae will appear significantly brighter.

Zero Image-Shift Microfocuser
Optional for the 8”, 10”, 12”,14” and standard with the 16” models, allows you to obtain precise image focus with no image movement. Perfect for astroimaging or during planetary observation. Focus is controlled thru the Autostar II handbox.

Oversize Primary Mirror
Diameters are greater than their listed aperture (e.g., the diameter of the 8” LX200-ACF is actually 8.25”). This additional 1/4” yields a wide, fully illuminated field-of-view. Primary Mirror Lock locks the mirror in place preventing movement during long-exposure astrophotography.
