Meade 12" ACF LX90 Telescope

The Meade 12-inch 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-field. ACF is the perfect solution for the serious astro-imager 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 LX90 also comes equipped with the AudioStar® Computer with Astronomer Inside technology, 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 built-in speaker.

Key Features of the Meade 12-inch LX90 Telescope

  • GPS- Built-in Sony GPS sensor determines your precise date, time and location for precise alignment.
  • 8x50 Viewfinder- 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, stars, constellations, clusters, nebula, galaxies and 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.
  • Oversize Primary Mirror- The primary mirror is larger in diameters than its 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 mount's two arms (sturdy fork) 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%.

Took Meade 4 tries but I have a awesome scope now!!

Opt was very helpful and patient with the issue's I was having and they only sell the product!! It took Meade 4 tries to get a perfect scope to me and this all started in May and it's the end of August now!! But it paid off in a great way!! The scope performes excellent and after I trained the drive it's pretty much spot on with tracking!! It's a 12" and I have larger aperture scopes and it's spoiled me but this is very nice and impressive to see and easy to use!! Thank you Opt for helping through this situation. Now I need a imaging camera and x wedge and the metal painted to match dew shield.

I have a ****** 12" LX90-ACF GPS. The computer freezes up. I have to reboot and realign it to get it to work again. Headache. It started after I had it for 2 months. It's still under warrantee and Meade says they will fix it if I pay $400 for shipping! I will never buy another Meade product!

Great telescope . The drive mount quit working after start-up.

Like I said , the 12" ACF LX90 is a wonderful telescope, the best I ever had !. To bad about the computer controlled ALT / AS Mount DEC> thing. I ordered a Replacement. Hope it Works!! Fingers crossed.

Having issues at this moment and have contacted Opt and Meade and hopefully this can be fixed without having to ship this new product back??

Optics seem great! But Audio star system is not working properly! Declination motor will not shut off during auto alignment and have reset and performed procedures as in the manual but still not operating properly??

Trade up to LX90 12"

It was great. I'm looking forward to wearing my OPT tshirt to our Astronomy club's meeting.
