Description

Meade 14" f/8 ACF Optical Tube Assembly with the Losmandy-style dovetail. The bare essentials for an unbeatable price. We're proud to offer the f/8 OTA without the accessories for an ultra-low cost.

Building on Meade’s award-winning Advanced Coma-Free (ACF) optics, the 14" 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, and front and rear dust covers. Focal length 2845mm. OTA weight is 28.6kg.
