Meade 10" ACF LX90 Telescope

The Meade 10”ACF LX90 Telescope’s technologically superior optical design gives a flatter, and advanced coma-free field of view with pinpoint images all the way to the edge of the field. ACF is the perfect solution for the serious Astroimager or visual astronomer looking for reasonably priced observatory-class optics.

The LX90’s Advanced Coma-Free (ACF) optical system creates a flatter field, reduces astigmatism and eliminates diffraction spikes, bringing the highest level of optical performance at an affordable price to both advanced and amateur astronomers. In addition to top-of-the-line optics, the LX-90 also comes equipped with the AudioStar® Computer with Astronomer Inside, allowing you to not only find and track over 30,000 celestial objects, but to also experience a guided tour as you listen to audio content through its build-in speaker.



  • GPS- Built-in Sony GPS sensor determines your prices date, time and location for precise alignment.
  • 8X50 Viewfiner- quickly and easily locate and center deep sky objects.
  • AudioStar Controller- controls the telescope to find and track any of over 30,000 celestial objects and gives you an audio guide of astronomical objects including planets, starts, constellations, clusters, nebula, galaxies and much more!
  • Meade Ultra-High Transmission Coatings- increases total light transmission and image brightness by nearly 20% over Meade's standard coatings. Objects such as stars, galaxies and nebulae will appear significantly brighter.
  • Oversized Primary Mirror - primary mirror is larger in diameters than its listed aperture listed aperture This additional 1/4-inch yields a wider, fully illuminated field-of-view, and allows you to see the light other telescopes leave behind.
  • Smart Drive -Meade AudioStar 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.
  • Auto-Align- picks two alignment stars for you and places directly in your telescope’s viewfinder, which then allows you to center them and fine-tune your alignment.
  • Rigid Cast Aluminum Fork Mount- the mounts two, sturdy fork arms give the LX90’s Optical Tube Assembly a solid platform for Astrophotography.

Included Technology

Advanced Coma-Free Optics (ACF)

Building from a classic RC design, Meade created a new design with coma-free pinpoint star images and flatter field. The ACF design reduces astigmatism and eliminates dffraction spikes found in classical RCs. TheACF is the perfect plattfor for the demanding researcher and imaging enthusiast with telescopes available in aperture of 6-inches, 8-inches,10-inches, 12-inches, 14-inches, and 16-inches

Ultra-High Transmission Coatings (UHTC)

Specialized Multi-layered coating that are preciesely designed to improve the performance of your telescopes optics. You'll see brighter star clusters, more fine details in nebulas, and more surface features on planets with UHTC than without. Averaged over the entire visible spectrum, total light transmission to the focus increases by 15%.

Ask a Question
  • Will the 10" LX90 accommodate 2" diagonals/eyepieces or is the OTA only designed to accept 1.25" diagonals/eyepieces?

    Hi Dennis, Despite the 10" LX90 including a 1.25" visual-back and diagonal, the optical-tube is fully compatible with 2" accessories/eyepieces. It is simply a matter of adapting to 2"... If you are looking to use 2" eyepieces, the most straight-forward

  • If the tripod included here a folding tripod? I short can it be dissembled / folded for ease transportation?

    The used Losmandy G11 Gemini 1 has the older non-folding tripod. The legs, however, can be removed from the central tripod hub by loosening the top clamps and can then be put into a large telescope tripod bag for easier transport.

  • Would this be compatible for another OTA, ex., an ETX-125 and what mounting attachments would be required?

    You can use other light OTA's as long as you can mount a Vixen style dovetail on the side. Note that the radius on the clamp housing on this mount is smaller (made originally for a 90mm scope) so you may need a spacer between the dovetail and the scope t

  • How stable is this scope for visual observing ? There is a 20 lbs difference between the LX200 and the LX 90 10 inch versions which must have some ramifications for observing. Put another way, if the LX 90 is up on a hill with a 10MPH wind is it going to

    Thank you for your question. This telescope is actually quite stable for visual observing even if you were going to be using this in a little wind. Now of course if it was a very windy night where the wind was 30+ MPH, then no telescope would be good to

  • 1. What are the major differences from LX200 series 2. Can I polar align using a Wedge ? 3. What is the total weight including mount ?

    1. The LX90 is lighter than the LX200 scopes with thinner fork arms, smaller gears, a smaller object database, and unlike the LX200 it has no motion hard stops. 2. The LX90 can use the same wedge as the LX200, but you must add the LX90 Wedge Adapter plat
