A T-adapter connects your camera body to the telescope so the scope acts as a large telephoto lens for prime-focus imaging. The system has two halves: a T-ring specific to your camera's lens mount, and an adapter tube that fits the telescope's focuser or thread. Confirm the tube matches your focuser, whether 1.25 inch, 2 inch, or an SCT thread, and that the T-ring uses the universal T2 thread so the two pieces join reliably. Some adapters also allow eyepiece projection for higher magnification.

These adapters suit DSLR and mirrorless owners taking their first step into astrophotography of the Moon, Sun with a proper filter, or bright deep-sky objects. A practical tip: buy the T-ring made for your exact camera mount, since it is the only camera-specific part, then a standard T2 adapter tube handles the telescope side and can be reused if you later change scopes.
