Meade LX600 16" F/8 ACF Optical Tube Assembly


Meade's LX850 16-inch Advanced Coma-Free (ACF) optical tube features a fast f/8 design making it an optimal choice for astrophotographers needing a large aperture system. Specialized baffling provides high-contrast images that are crisp from edge to edge. 

Meade's proprietary ACF optical design goes a step beyond traditional Schmidt-Cassegrain telescopes by shortening the focal length and improving image clarity, color and contrast. Advanced Coma-Free optics display stars crisp and clear throughout the image circle.

Meade LX850 16-inch ACF OTA Features

  • 3251 mm focal length gives you a focal ratio of f/8 making this a fast Cassegrain-style design, reducing exposure times without sacrificing image quality.
  • Carefully designed internal baffling maximizes light transmission for optimal contrast and brightness.
  • An internal Crayford-style focusing system moves the primary mirror with zero backlash or image shift and has a 7:1 focusing speed ratio which smooth and precise.
  • Signature blue matte pebble finish on the optical tube is both durable and beautiful.


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%.
