Meade 16" / 20" LX400 ACF Advanced Coma-Free Telescopes on MAX Robotic German Equatorial Mount are a huge jump over the traditional Schmidt-Cassegrain as far as sharpness of image, flatness of field, and color. Meade Advanced Coma Free Telescopes deliver the same sharp, flat, coma-free field from edge to edge as a typical Ritchey-Chretien. The use of the corrector plate in the ACF system creates a closed and protected optical tube, reduces astigmatism and eliminates the diffraction spikes inherent in the traditional RC design. ACF optical system perform at the same high level as comparable RC systems costing thousands more. Imagine you're a seasoned astrophotographer saving up for the fast f-ratio, wide-field, comafree, custom telescope of a lifetime. The Telescopes that can handle the largest CCD chips. The telescope with state-of-the-art optics and mechanics. The <>telescope that is praised as "approaching perfection" by industry critics and astronomers alike. Suddenly you find out such Telescopes is available for one-fifth of what you thought - and you won't have to wait six months for it to be built. What would you do? You'd buy one.![]()
In the hands of the serious astronomer or astrophotographer the Meade 16in / 20in LX400ACF Advanced Coma Free Telescope is an instrument that will produce razor sharp star images across the entire field of view on par with the best professional observatories. Meade Advanced Comafree optical design produces a coma-free, flat field of view that rivals traditional RC telescopes at a fraction of the cost. Meade ACF design even eliminates diffraction spikes and improves astigmatism, both of which are inherent in the traditional RC design.
