LX90-ACF
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.

LX90-SC
Meade's Schmidt-Cassegrain (SC) optics give you high performance for the best possible price. For the person looking to get the most from their astronomical dollar, look no further. Meade uses water-white glass with superior light transmission across the entire visible spectrum, unlike inferior standard plate glass used by other telescope manufacturers. Combined with our industry-leading Ultra-High Transmission Coatings (UHTC) -- with 15% better light transmission than standard coatings -- and oversized, thermally-stable Pyrex? primary mirrors for optimum light collection, you get a spectacular viewing experience not available on comparable competitors' telesscopes.

LX90-ACF
For the truly discerning astronomer who will not tolerate anything but the very best, there is Meade's Advanced Coma-Free (ACF) optical system. ACF takes all of the features of our SC models and then ups the ante. With it's technologically superior optical design, ACF gives a flatter, coma-free field of view with pinpoint images all the way to the edge of the field, rivaling Ritchey-Cre'tien performance at a fraction of the cost. ACF is the perfect solution for the serious astroimager or visual astronomer looking for observatory-class optics.

GPS - LX90 can do more than track satellites. It talks to them as well. Turn it on and the built-in Sony(R) GPS sensor immediately determines your precise date, time and location. AutoAlign(TM) then uses this info to align your scope for a tour of the most spectacular sights in the universe.	SLEW SPEED – The LX90 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 will show you two to three times more objects.
EASY ALIGN(TM) –LX90s are smart scopes that know the night sky right out of the box. Easy Align picks two 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.	RIGID CAST ALUMINUM FORK MOUNT – The Meade LX90's Optical Tube Assembly is mounted on two sturdy fork arms giving you a rock solid platform for astrophotography. LX200(TM) - SERIES TRIPOD – The LX90 comes standard with the same sturdy field tripod as the LX200-ACF series telescope.
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.	SMART DRIVE(TM) – Meade’s AutoStar? provides Periodic Error Correction (in polar mode). Over the course of one or more training periods your LX90 will minimize guiding corrections during long exposure astrophotography.
8 X 50 VIEWFINDER – Quickly and easily locate and center deep sky objects.	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 will grow with you for years to come.
