Meade 8 Inch LX200-ACF Advanced Coma-Free Telescope with UHTC The most widely used research telescope on earth now comes with the most advanced optical system. 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-Chrtien (RC) including NASA's Hubble Space Telescope. Now you can own optics similar 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 Super Plssl eyepiece. The new LX200-ACF: It's the biggest news in astronomy since well the LX200. The advanced in Advanced Coma-Free.A traditional Ritchey-Chrtien (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 ACF design. When reviewing Meade's LX200-ACF Advanced Coma Free Sky and Telescope magazine said It does indeed perform like a Ritchey-Chrtien. The difference between the off-axis images (compared to a Schm
