The Meade Instruments 16" f/8 ACF Optical Tube (OTA) features a 16” 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 3,251mm.

An optional 2” diameter, 3-element f/5 focal reducer/field flattener (sold separately) lets you gain even wider, flatter fields with faster exposures, even on larger sensors.

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.
