A T2 ring is used to attach your Canon DSLR to telescope instead of camera lens. I had two T2 rings, and this one was not used often, so condition is as new. Made of aluminium alloyIf you have any questions, please feel free to ask. Decided to sell all equipment I have, because of lack of time, changed life-style, lack of place to store. So you are welcome to check other my listings for a bargain.
