Alpine Astronomical Baader Wide T-Ring Set for Canon EOS R

A part of their modular Astro T-2 system, the Alpine Astronomical Baader Wide T-Ring Set is made up of two parts: The camera-specific bayonet mount ring and an inner adapter ring with standard T-2 female threads. The bayonet ring is designed specifically to fit Canon EOS R DSLR cameras and provides a safe and secure connection.

Out of the box, it will work like a conventional T-ring: It is compatible with all T-2 accessories on the marketincluding Baader s entire T-2 Astro modular line. But unlike conventional rings, the inner threaded ring can be unmounted from the bayonet ring, allowing the bayonet ring to be used with Baader s S52 rings and accessories. Removing the inner T-2 adapter presents a larger clear aperture than a normal T-ring, which is good for full-frame cameras.

The bayonet ring can also be directly mounted to Baader s Universal Filter Changer (UFC) System without the need for additional adapters. This direct-connection capability provides a solid connection without adding any optical distance. Additionally, a more conventional 2" nosepiece can be installed on the bayonet ring in place of the T-2 ring for mounting your camera body directly into 2" eyepiece holders or accessories.
