Meade 16" F/8 ACF Optical Tube Assembly
Meade's 16" 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. 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.
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 are exactly that, coma free. Stars are crisp and clear throughout the image circle. This revolutionary design provides the kind of image quality that was previously only seen in Ritchie-Chretien and similar astrograph designs which typically carry a might higher price tag at this aperture. By employing the ACF design, Meade has been able to offer professional grade optical quality at a never-before-seen price.
