Product Description

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.

The LX200-ACF includes all the field-proven features of the LX200 including GPS, Primary Mirror Lock, Zero Image-Shift Microfocuser, 2" Diagonal Mirror, 26mm Series 5000 Plossl Eyepiece and 18v AC Adapter. Plus, the LX200-ACF comes with observatory-class optics crafted in Irvine, California. The new LX200-ACF. It’s the biggest news in astronomy since, well, the LX200. The new LX200-ACF. It’s the biggest news in astronomy since, well, the LX200.

Includes the OTA, Base, Fork, Accessories and Super Giant Field Tripod.
