| The NEW LX90-ACF represents the latest step in the evolution of the LX90, featuring Meade's f/10 ADVANCED COMA-FREE OPTICS: Building from a classic RC design, Meade has created a new optical design with the same coma-free pinpoint star images and flatter field that discerning astrophotographers and most professional observatories expect. The NEW LX90-ACF with Meade’s Advanced Coma-Free system also reduces the astigmatism and eliminates diffractions spikes found in classical RCs. No competing Schmidt-Cassegrain Telescope can make those claims. The LX90-ACF is the perfect platform for the demanding visual observer and imaging enthusiast with telescopes available in apertures of 8 inches, 10 inches, and 12 inches. When it comes to industry-leading optics, depth of features, and computerized operation, the LX90-ACF is the best all-around telescope value you can find. |

GPS - LX90-ACF can do more than track satellites. It talks to them as well. Turn it on and the built-in Sony® GPS sensor immediately determines your precise date, time and location. AutoAlign™ then uses this info to align your scope for a tour of the most spectacular sights in the universe. With all the features of the legendary LX90GPS, plus the additon of Advanced Coma-Free optics and the ability to communicate to satellites, the new LX90-ACF now has it all.
AUTOALIGN™ – Telescopes with Meade’s new AutoAlign come pre-aligned. They are smart scopes that know the night sky right out of the box. AutoAlign picks two fail-proof alignment stars for you and places them right in your viewfinder. Just center them to fine tune your alignment and the wonders of the universe are at your fingertips.
OVERSIZED PRIMARY MIRROR – Only Meade manufactures their primary mirrors in diameters larger than their listed aperture (e.g. the diameter of the 8" LX90’s primary mirror is actually 8.25").This additional 1/4" yields a wider, fully illuminated field-of-view, and allows you to see the light other telescopes leave behind.
SMARTFINDER™(RED DOT) & 8 X 50 VIEWFINDER – Quickly and easily locate and center deep sky objects. |
|
SLEW SPEED – The LX90-ACF slews (moves) from star to star at 7 degrees per second. That is more than twice as fast as the competition. This means that over the course of an evening, a Meade LX90-ACF will show you two to three times more objects.
RIGID CAST ALUMINUM FORK MOUNT – The Meade LX90-ACF's Optical Tube Assembly is mounted on two sturdy fork arms giving you a rock solid platform for astrophotography.
LX200™ - SERIES TRIPOD – The LX90-ACF comes standard with the same sturdy field tripod as the LX200-ACF series telescope.
SMART DRIVE™ – Meade’s AutoStar® provides Periodic Error Correction (in polar mode). Over the course of one or more training periods your LX90-ACF will minimize guiding corrections during long exposure astrophotography.
AUTOSTAR CONTROLLER – Meade’s AutoStar® can be updated after purchase. Click here to download software upgrades, guided tours and timely objects like comets, satellites and new discoveries – Free! Keep your AutoStar up-to-date, and your LX90-ACF will grow with you for years to come. |

Premier Edition |

 |
Just because a star may be millions of years old, doesn't mean it should take you that long to find it.
Until now, the stargazer's two biggest challenges to enjoying the night
sky have been aligning their telescope and finding objects. Meade’s new
ETX Premier Edition eliminates these two challenges and makes astronomy
as easy as pushing a button – right out of the box. Want to see a
hard-to-find deep space galaxy? Simply push a button. The same goes for
planets, stars, nebulae and more. Just pick an object you want to
observe, press a button, and then AutoStar® will automatically point your telescope and put it right in your eyepiece.
Don't know what you want to see this evening? Go to the “Tonight's Best™” tour in your AutoStar.
It automatically selects the best objects in the sky for that
particular time and location (from its database of over 30,000
celestial objects). All you need is a clear night, a dark sky and a
little curiosity. Whether you already know the sky by heart, or are
just beginning your journey of discovery, your Meade ETX-Premier
Edition will take you where you want to go. Astronomy has never been so
fun and rewarding. |

Automatic Alignment + SmartFinder™
Meade's new ETX-Premier Edition automatically levels your telescope,
points it to North and sets the time. You just enter your location or
zip code. After your ETX completes its patented Level North automatic
alignment procedure it will point to the first alignment star. Use the
new wide-field SmartFinder to center the red dot over the alignment
stars for ultra-precise pointing accuracy. It’s that easy. |

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, SmartDrive™, Smart Mount™,
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.
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. 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 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.” |

f/10 Advanced Coma-Free Optics: Building from a classic RC design, Meade has created a new design with
the same coma-free pinpoint star images and flatter field that
discerning astrophotographers and most professional observatories have
come to expect from classic Ritchey-Chrétien optics. Meade’s Advanced
Coma-Free system also reduces the astigmatism and eliminates
diffractions spikes found in classical RCs. The LX200-ACF is the
perfect platform for the demanding researcher and imaging enthusiast
with telescopes available in apertures of 8 inches, 10 inches, 12
inches, and 16 inches.
Meade Ultra-High Transmission Coatings (UHTC™) increases total light tran+smission and image brightness by nearly 20%
over Meade’s standard coatings. Objects such as stars, galaxies and
nebulae will appear significantly brighter.
Zero Image-Shift Microfocuser allows you to obtain precise image focus with no image movement.
Primary Mirror Lock locks the mirror in place during long-exposure astrophotography.
Oversize Primary Mirror diameters are greater than their listed aperture (e.g., the diameter of
the 8" LX200-ACF is actually 8.25"). This additional 1/4" yields a
wide, fully illuminated field-of-view.
Smart Mount™ constantly refines pointing accuracy each time an object is centered
and updated. Compatible with both equatorial and altazimuth mounts. |
|
Smart Drive™ provides permanent periodic error correction (PPEC) on both axes by
learning and averaging error over the course of one or more training
periods, thereby minimizing guiding corrections during long-exposure
photographs. PPEC is available on both axes and functions in both polar
and altazimuth modes.
Sony®GPS Receiver Sensor automatically inputs precise time, date, and geographical location to help quickly and precisely align the telescope.
AutoAlign™ – Telescopes with Meade’s new AutoAlign come pre-aligned.They are smart
scopes that know the night sky right out of the box. AutoAlign picks
two fail-proof alignment stars for you and places them right in your
view-finder. Just center to fine tune your alignment and the wonders of
the universe are at your fingertips.
AutoStar® II controller features “Hot Keys” for quick access to a 145,000 celestial
object database. AutoStar II can be updated with the latest software
upgrades, guided tours and timely objects like comets free at meade.com.
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.
