Meade - 14" ACF Advanced Coma-Free f/8 Optical Tube Assembly - (UHTC)

Meade 14" ACF Advanced Coma-Free Optical Tube Assembly

  The Meade Instruments 14" f/8 ACF Optical Tube Assembly (OTA) features a 14” aperture, f/8 optical system with Meade’s Advanced Coma Free (ACF) optics and high-contrast baffling that ensures crisp, pinpoint imaging to the very edge of the field. The OTA features an internal zero image shift 3” Crayford-style 10:1 focusing system with a 2-speed, 7:1 reduction control that rigidly holds the OTA’s primary mirror, eliminating the need for a mirror lock, and provides smooth, precise focusing. The OTA has a focal length of 2,845mm.

The OTA comes with a precision-machined Losmandy-style dovetail rail mated to the tube with wide-stance radius blocks for steady mounting and front and rear dust covers.
