Description

Note: This OTA does not come in its original box. This is a new item with full UK warranty.

Building on Meade’s award-winning Advanced Coma-Free™ (ACF™) optics, the 14" optical tube assembly (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.

Meade 14" f/8 ACF Optical Tube Assembly #1408-80-01 includes a 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 29 kg (63 lbs).

Mirror lock

All ACF f/8 models feature a primary mirror locking mechanism, which effectively prevents movement of the primary mirror during long exposure astrophotography or observing. Turn the lock knob located just above the telescope’s main focus knob and the progressive-tension primary lock completely cancels any residual image shift due to mirror movement during visual, photographic, or imaging applications.
