Meade 20" LX400-ACF Advanced Coma-Free Telescope on MAX Robotic German Equatorial Mount Product Info

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 imagefar 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 telescope 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 telescope 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.

Meade 16 in. / 20 in. LX 400 ACF Coma Free Telescopes highlights:

  • Meade LX400ACF is The Remote Control Observatory. Control your Meade LX400 ACF Telescope from the comfort of your home, office, or even out-of-town with completely integrated Meade AutoStar II and LX400ACF software systems. Access the computer that controls your telescope via network or Web access. Work like the pros, imaging whenever the weather, your schedule, and the universe align. With Meade LX400 ACF Advanced Coma-Free Computerized Telescope, you have your own remotely controlled observatory - control your telescope from your computer. Just set-up, connect, control, and image. Meade AutoStar II makes it easy.
  • Meade Advanced Coma-Free Telescopes LX-400 ACF provide perfect star images edge-to-edge. This professional level of off-axis performance was previously unavailable without spending more than three times the cost of an LX400ACF.
  • Leveling made easy. New quick release locks are located at the top of the tripod legs (instead of the bottom). Legs can be extended or retracted with a flip of the waist-high lever. Especially helpful on uneven ground.
  • MAX Robotic German Equatorial Mounts: MAX features a unique modular design that allows a couple of individuals to assemble, either permanently or transportably, a mount twice the size of any other commercially available mount. The mount breaks down into a Portable Pier (tripod), Pedestal, RA Housing Assembly, and DEC Housing assembly. Together all of the components and an OTA assembly fit easily into a station wagon, SUV, minivan or small truck. When assembled, quick release, but rock solid, dovetail plates allow OTA and instrument packages up to 250 lbs to be quickly mounted and de-mounted.
