I have been trying to attach my DSLR to my telescope via a T-Ring. The T-Ring appears to be made up of a wider ring which clips into the camera and an inner ring which screws into the telescope focuser.
The problem I’ve found is that the inner ring just spins with absolutely no resistance, so when I attach it to the telescope, the camera swings with the adapter. The inner ring also has a bad habit of falling out of the outer ring, risking the camera falling to the floor and suffering damage!
Am I doing something wrong? Have I been unlucky enough to buy a faulty T-Ring? Thanks for your help!
