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 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 Schmidt Cassegrain) was dramatic to say the least.     f/10 Advanced Coma Free Optics: Building from a c Rokform Lanyard Movavi launches Video Editor 9
