Meade - 12" LX90-ACF (f/10) Advanced Coma-Free Telescope with UHTC Coatings


Discontinued Product

Manufactured by: Meade


This is a discontinued product. We recommend the Meade - 12" LX90-ACF (f/10) Advanced Coma-Free Telescope with UHTC Coatings as a replacement.


  • The Meade 10" LX90-ACF Telescope sports an advanced coma-free design that includes 254mm (10") of clear aperture, 2540mm (f/10) focal length and comes with Meade's high transmission UHTC coatings.

  • ACF gives a flatter, coma-free field of view with pinpoint images all the way to the edge of the field.

  • The Meade 10" LX90-ACF Telescope reduces astigmatism and eliminates diffraction spikes.
  • Includes rigid cast aluminum fork mount and LX200 Series tripod.


  • The Meade 10" LX90-ACF comes fully equipped with a Sony GPS receiver, an oversized primary mirror with diffraction limited optics, 

  • Perfect solution for the serious astroimager or visual astronomer looking for observatory-class optics.


Building from a classic RC design, Meade has created a new design with the same coma-free pinpoint star images and flatter field also reduces the astigmatism and eliminates diffractions spikes found in classical RCs. The LX90-ACF is the perfect platform for the demanding researcher and imaging enthusiast with telescopes available in apertures of 8 inches, 10 inches, and 12 inches. However, let's get to step one first and disect why ACF technology is so beneficial and how it functions. Using the fundamentals behind the Ritchey Chretien design, ACF just adds even more to the big picture. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. Coma is very similar to diffraction effects, in which light from a specific object cannot be focused properly and therefore results in fuzzy. undetiled, and inaccurate images. Since this is purely an optical aberration and widely understood, there is absolutely NO reason why it cannot be fixed to near perfection. With this new technology by Meade directly built into the optics, observors can now obtain a more aplanatic (coma-free) and spherical free telescopic experience. Years ago, this luxury would've costed a minimum of a few thousand dollars, but with Meade's invention, that is pure HISTORY!

Product Series

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. 

GPS - LX90 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. 

EASY ALIGN™ - 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. 

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. 

8 X 50 VIEWFINDER - Quickly and easily locate and center deep sky objects

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. 

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™ - SERIES TRIPOD - The LX90 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 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 will grow with you for years to come.
