These superb large aperture instruments are capable of serious research and education and are widely in use all over the world in some of the world's leading learning establishments. We have years of extensive experience in the supply and installation of these fine 16" systems, highly recommended.
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 Meades 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.
Meade UHTC is a series of exotic optical coatings precisely tuned to optimize the optical performance of your LX telescope. Image brightness is increased by nearly 15% over standard coatings. Objects such as stars, galaxies and nebulae as observed through your LX will be dramatically brighter. Even observations of the Moon and planets will benefit in increased image brightness from the full spectrum of light transmission.
