12'' f/8 ACF Optic with tube with UHTCAdvanced Coma Free Optics with UHTC
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, and front
and rear dust covers.
