Coma-Free Telescopes 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-Chrétien (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, Zero
Image-Shift Microfocuser, Oversized Primary Mirror, SmartDriveT, Smart MountT,
AutoStar® II and more. Plus, the LX200-ACF comes with observatory-class optics
and a Series 5000 26mm 5-Element Plössl eyepiece. The new LX200-ACF. It's the
biggest news in astronomy since, well, the LX200. |
Advanced Coma-Free Telescope with UHTC 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. 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. |
