Baader Wide T-Ring for Canon EOS

The Baader Planetarium Wide T-Ring connects Canon EOS DSLR cameras to the Astro T-2 system using a Canon EOS bayonet on the camera side and an S52 dovetail clamp with internal T-2 thread on the telescope side. It is built new for astrophotographers who need a secure, wide-aperture link between their camera and telescope or accessory train.

For imagers needing maximum illumination

This ring suits Canon EOS owners who want the largest possible clear aperture to reduce vignetting on full-frame or APS-C sensors. It is not for users with non-Canon camera mounts, nor for setups that require a direct M48 or M68 thread without the optional adapters listed in the system.

41 mm clear aperture on the T-2 side

The internal T-2 thread provides a 41 mm clear aperture, while the S52 dovetail inner diameter measures 48.1 mm, allowing full-frame illumination when paired with compatible Baader accessories.
