We've heard your requests, and we listened. That's why 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 12" OTA employs a fast f/8 optical system with high-contrast baffling that ensures 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.
The ACF primary, secondary and corrector plate glass blanks are manufactured in the USA exclusively for Meade.
