Designed specifically for Canon EOS cameras, the Wide T-Adapter from Tele Vue is used to connect your DSLR to any of their astroimaging accessories, like the 0.8x Reducer/Flattener. Standard T-rings/telescope setups do not take advantage of the wide aperture of a bayonet mount and can cause significant vignetting because of the small diameter of their T-ring openings. This 2.4" Canon EOS Wide T-Adapter's bayonet mount connects to your camera in place of the T-ring and provides 50% greater aperture to minimize vignetting.

Works fine

I also noticed some excessive play but I was able to fix that by tightening the small screws. It's been working fine for me for over 3 years now.
Canon T Adapter has excessive play

The Tele Vue Canon Wide T Adapter was delivered on time from B&H. The Tele Vue 127is/101is fitting part works fine. But, the attached Canon T Adapter, like many Canon T Adpaters, suffers from excessive play. It does not fit tightly on any of my Canon EOS cameras, and it's not suitable for long exposure astro-photography. I had to replace the Canon T-adapter on the Televue 127is/101is fitting with another Canon T-adapter that I had been using for another purpose.

Will this fit Canon EOS R series?
Will this fit Canon EOS R series?
No, the Tele Vue Wide T-Adapter (Canon EOS) [BH #TEACWT] is only compatible with the older EOS Canon mount.
For the newer RF mount you can use this adapter; Vello T-Mount Lens to Canon RF-Mount Camera Lens Adapter [BH #VELACRFT • MFR #LA-CRF-T].

question
Would this adaptor work on for a Canon 5DM3 ?
Yes, it would physically work, however with the full frame sensor of the 5DM3, you would likely still get vignetting if you are using it with a 2 focuser or paracorr.

question
Will this adapter work with the Tele Vue T-Ring Adapter for the 4x Powermate?
Yes. Worked for me. But to reach focus with my 101mm refractor I also required an extension tube.
