The Meade Instruments LX85 6" f/12 Maksutov-Cassegrain Telescope has a large aperture and long focal length, despite its short optical tube length, to allow you to make detailed observations of near and deep-sky objects.

Utilizing a convex meniscus lens, a large primary mirror, and a smaller secondary mirror, the Maksutov-Cassegrain optical configuration limits obstruction and increases contrast and sharpness versus the more popular Schmidt-Cassegrain configuration. Performance is further improved with Meade's proprietary Ultra-High Transmission Coatings (UHTC) system, which improves light transmission through the light path across the entire visible spectrum. A combination of high-transmittance lens coatings and highly reflective mirror coatings boosts image brightness, while minimizing external light loss and internal diffraction.

This LX85 is offered here without a mount or tripod for users who already have a reliable support system and are looking to upgrade their optical tube assembly (OTA) or add another to their astronomy kit. It comes outfitted with a Vixen-style dovetail rail to make it compatible with a wide variety of alt-azimuth, equatorial, and GoTo mounts available from most manufacturers. To help get you started, Meade includes two eyepieces that produce low and high magnifications, a 90° star diagonal, and an 8x50 finderscope.

Optical Tube Assembly

  • Large 150mm (6") aperture is ideal for viewing inside the solar system and far outside it
  • f/12 focal ratio
  • Long 1800mm focal length enables high magnifications for detailed lunar and planetary viewing
  • Front convex meniscus lens corrects spherical and chromatic aberrations and comas (off-axis aberrations) across the entire field of view
  • Small secondary mirror attached to rear of lens reduces obstructions and increases contrast
  • Ultra-High Transmission Coatings (UHTC) system
  • Single-speed internal focusing mechanism moves the primary mirror forward and back to achieve tack-sharp images with virtually zero backlash
  • 2" visual back allows the use of larger eyepieces and accessories, and a 1.25" reducer adapter further expands compatibility

Ultra-High Transmission Coatings (UHTC)

  • All corrector plate and mirror surfaces are fully multi-coated
  • Engineered to optimize visual, photographic, and CCD imaging
  • Improve light transmission across the entire visible spectrum through the optical path
  • Corrector plate coatings made up of multiple layers of aluminum oxide (Al2O3), titanium dioxide (TiO2), and magnesium fluoride (MgF2)
  • Mirror coatings consist of aluminum with multi-layer coatings of titanium dioxide (TiO2) and silicon dioxide (SiO2)


  • Optical tube assembly (OTA) only. Mount and tripod required for proper use
  • Vixen-style dovetail plate is compatible with a wide variety of mounts
  • OTA weight: 12.4 pounds

Included Accessories

  • 1.25"-diameter nosepiece accepts most astronomical filters
  • 9mm eyepiece produces a high 200x power
  • 26mm eyepiece yields a low 69x magnification
  • 2" nosepiece and holder allow the use of larger eyepieces and accessories like Barlow lenses
  • 90° angle places user's head in a more comfortable position when the scope is pointed directly overhead
  • Star configuration corrects viewing horizontally, but not vertically
  • Use included reducer for the included eyepieces or other 1.25" accessories
  • Low 8x power ensures a wide field of view for faster alignment and easier star-hopping navigation
  • Large 50mm aperture produces bright images to more easily find alignment stars
  • Crosshair reticle enables precision centering, requiring less fine-tuning in eyepiece
  • Includes mounting bracket
