Celestron T-Ring for Canon EOS

A simple yet invaluable device. It fit my camera perfectly. I was able to use the T ring which fits with the T adapter and take photos with my canon EOS Rebel T7 converting my Celestron telescope as a lens.

T-Ring for Camera connection to Celestron telescope

T-Ring fits perfectly between my EOS camera and the telescope. For connecting an additional T-Adapter is required. The description on that t-Ring was not 100% clear to me.
