## Description

The Baader HDT54 28 mm Hyperion Digital T-Ring enables you to couple practically any digital camera, camcorder, or CCD Camera directly to the 54 mm thread of the Baader Hyperion fixed focal length eyepieces and Mark II Clickstop Zoom. Hyperion makes the ideal projection eyepiece for afocal projection imaging, delivering a very sharp projected image without any vignetting.The direct threaded coupling permitted by the Digital T-ring results in the most accurate and rigid attachment possible even with large and heavy cameras and video cameras. This system also allows the camera's lens to be located immediately above the large eyelens for eliminating the vignetting common in other systems (afocal projection).

## Features

- For attaching cameras with 28 mm filter thread, you will need the appropriate HDT ring as well as a 54 mm extension ring (sold separately)
