Meade 12" f/8 ACF Optical Tube Assembly #1208-80-00.

Building on Meade’s award-winning Advanced Coma-Free™ (ACF™) optics, the 12" 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, and diffraction-limited optics.

Includes precision machined Losmandy-style dovetail rail mated to the tube with wide-stance radius blocks for rock-steady mounting, Series 5000 enhanced 99 percent reflectivity diagonal, 8x50 finderscope with quick release mounting bracket, Series 5000 HD60 25mm eyepiece, and front and rear dust covers.
