Meade LX850-ACF overview

  • 1Description

With the smallest aperture in the series for a combination of power and portability, the Meade Instruments LX850-ACF UHTC 10" f/8 Catadioptric Telescope utilizes their Advanced Coma-Free (ACF) catadioptric light path to reduce color fringing and off-axis comas, enabling it to clearly resolve dim deep-sky objects and easily split binary stars with tack-sharp clarity. Complementing the ACF system is their Ultra-High Transmission Coatings (UHTC) system that improves light transmission through the entire light path across the whole visible spectrum. A combination of high-transmittance lens coatings and highly reflective mirror coatings boost image brightness, while minimizing external light loss and internal diffraction.

Meade built this series for users who have a reliable mount and support system with all their favorite eyepieces and accessories, so this LX-850 is offered here as just the optical tube assembly (OTA)—other required accessories such as visual backs, finders, eyepieces, and diagonals are also not included. Meade only includes a large Losmandy-style dovetail plate, with sturdy and stable radius blocks for added strength, to make it easier to install on a mount out of the box, and a factory-installed dovetail finder saddle that will accept most Meade finder brackets.

Optical Tube Assembly
  • Large 10" (254mm) aperture allows for detailed lunar and planetary viewing with the ability to resolve deep-sky objects
  • Moderate f/8 focal ratio makes it a competent optic for astrophotography and imaging
  • Long 2032mm focal length, despite compact form factor, provides a high magnification potential
  • Advanced Coma-Free (ACF) catadioptric design
  • Ultra-High Transmission Coatings (UHTC) system
  • Resolution: 0.456 arcsec, Dawes' Limit
  • 7:1 dual-speed internal Crayford focuser enables fast coarse and precise fine focusing with zero backlash—especially useful for viewing deep-sky objects and splitting binary stars or clusters
  • Standard Schmidt-Cassegrain visual back threads accept most screw-on backs and accessories
  • Factory-installed finderscope dovetail saddle accepts compatible finders
Optical Technologies
Advanced Coma-Free System:
  • Reduces off-axis comas and astigmatism for sharper images
  • Eliminates diffraction spikes for better resolution
  • Aplanatic design produces flat, distortion-free images across the field of view—especially at the edges
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)

 

Mounting
  • Optical tube assembly only—mount and tripod required for proper use
  • Large Losmandy-style dovetail plate for use on compatible saddles
  • Radius blocks help provide strength and stability to rail
  • Weight: 33 pounds
