Meade 406mm (16 inch) F/8 Advanced Coma-Free Telescope Optical Tube Assembly
Building on Meade’s award-winning Advanced Coma-Free™ (ACF™) optics, the 16" OTA employs a fast f/8 optical system with high-contrast baffling that insures crisp, pinpoint imaging to the very edge of the field. Features an internal zero image shift Crayford-style focusing system with a two-speed 7:1 reduction control that provides smooth, precise focusing at any magnification. Also features Meade's Ultra-High Transmission Coatings (UHTC) for maximum brightness and contrast, an oversized low-expansion primary mirror for extra aperture and to prevent thermal expansion of the mirror, primary mirror lock for increased image stability, and diffraction-limited optics.
Includes precision machined Losmandy-style dovetail rail mated to the tube with wide-stance radius blocks for rock-steady mounting, and front and rear dust covers.
