This ring allows you to mount a Canon EOS digital camera directly to instruments like the Shelyak LISA, Lhires III, Alpy, or UVEX spectroscope. It transforms your DSLR from a photographic tool into a component of a scientific instrument, enabling you to capture stellar and nebular spectra.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eSecure Mechanical Link for Canon EOS Astrophotography\u003c\/h3\u003e\n      \u003cp\u003eThis adapter provides a rigid, non-rotating connection between the Canon EOS bayonet mount and the universal T-thread standard (M42x0.75). The all-metal construction ensures that your camera is held securely without flexure, which is critical for maintaining focus and alignment throughout an imaging session. Its low-profile design adds minimal length to the optical path, helping you reach focus with a variety of telescopes and accessories.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n  \n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eDesigned for Shelyak Spectroscopes: LISA, Lhires III, Alpy \u0026amp; UVEX\u003c\/h3\u003e\n      \u003cp\u003eWhile this T-ring works with any T-threaded accessory, it is the specific adapter recommended for attaching a Canon DSLR to Shelyak's line of high-resolution spectroscopes. Whether you are using a LISA, Lhires III, Alpy, or UVEX model, this ring provides the correct interface for a direct and stable attachment. This enables you to leverage your existing camera sensor for astrophysical research, such as classifying stars or analyzing the composition of nebulae.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the primary function of this T-Mount to Canon EOS adapter?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eThis adapter's primary function is to connect a \u003cstrong\u003eCanon EOS DSLR camera body\u003c\/strong\u003e to an accessory that has male \u003cstrong\u003eT-threads (M42x0.75)\u003c\/strong\u003e.

This is the correct adapter for connecting any Canon EOS camera body, including a full-frame model like the 5D Mark IV, to a Shelyak Lhires III spectroscope. The ring mates the camera's EF bayonet mount to the T-threads on the spectroscope for a secure fit.\u003c\/p\u003e\n  \u003c\/div\u003e\n    \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eI have a Canon EOS Rebel T7i.

This means it has a 42mm diameter with a 0.75mm thread pitch. This is a common standard in astronomy but should not be confused with the M42x1 \"Pentax screw mount\" used in older photography lenses.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I attach the T-ring to my Canon EOS camera?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eAttaching the T-ring is just like attaching a lens.
