A DSLR serves as my dedicated camera for astrophotography, which may be mounted onto a telescope for closeup shots of galaxies and nebulas. The DSLR is attached onto a telescope by means of a special type of adapter.
A T-ring is simply a metal adapter with one end that fits nicely to your lens mount (each brand has it’s own T-ring design) and with the other end that attaches to a T-adapter. The T-adapter is the one that attaches any T-ring to a telescope.
Each camera brand has a specific T-ring design and varies from one brand to another. This is usually supplied by the manufacturer or a third party-supplier. The Canon EOS T-ring shown in this setup is produced by Celestron. Some telescopes however, have threaded focusers that may accept a T-ring directly, thus, eliminating the need for a T-adapter.
