Wide T-Adapter for Canon EOS

The Wide T-Adapter for Canon EOS is a specialized astrophotography accessory that lets you directly mount a Canon EOS DSLR camera to a telescope’s focuser for prime focus imaging, without using a lens. Unlike standard T-adapters, this wide 2″ T-adapter provides an expanded, clear aperture of approximately 47.5 mm to minimize vignetting and fully utilize APS-C and full-frame sensors for wide-field captures. Its integrated Canon EOS bayonet securely connects with Canon camera bodies while the 2″ barrel fits standard 2″ telescope focusers, giving a stable and secure connection. The adapter is machined from black anodized aluminum for rigidity and durability, and features internally blacken threads to reduce stray reflections and improve contrast, key attributes for effective deep-sky imaging. With only about 10 mm of added optical length and compatibility with 2″ telescope filters, it’s a practical tool for astrophotographers looking to get sharp, wide-field images of the night sky.
