Thanks everyone. I will return the product then. How can I ensure that it will fit, is there any diameter I can check before buying.

Here is the YouTube link: Can you also let me know how can I fix the adapter firmly in the eyepiece of telescope as there is no thread/ only two screws are there.

Dear All, I am a complete newbie. I have a Celestron 130eq. I have a canon EOS1100D. I recently bought a Gosky T ring with adapter https://www.amazon.ae/dp/B013DID11A/ref=cm_sw_r_cp_apa_i_y9AmFb8TR66W0 that said it's compatible with all canon EOS. However the t ring doesn't fit my camera. How do I purchase the correct t ring. Also I just tried the adapter inside my telescope eyepiece. As there are no threads but just two side screw, I didn't feel it sturdy enough. So am I going about this whole thing wrong?
