The Baader EOS Protective Wide T-Ring with 7nm H-Alpha Filter is a precision Canon EOS DSLR adapter system featuring a pre-installed 50.4mm narrowband H-Alpha filter optimized for hydrogen-alpha deep-sky astrophotography. This system solves common T-ring limitations through optimized design and tight manufacturing tolerances that minimize focal plane tilt, wobble, and vignetting while providing dust protection for high-resolution imaging sensors. The included 7nm bandpass H-Alpha filter delivers excellent contrast for nebular imaging with high transmission and minimal reflections, halos, or ghosting thanks to Baader's premium hard-coated optics.
