EOS Protective Wide T-Ring with UV/IR Blocking Filter - DSLRT-UVIR

This Baader Canon EOS T-ring system combines a protective wide T-ring with a pre-installed 50.4mm UV/IR blocking filter optimized for DSLR astrophotography. The 2-inch wide-aperture design accepts three interchangeable attachment adapters (T-thread 42mm, 2-inch nosepiece, and 48mm astro filter thread) to maximize compatibility with various telescope optical systems. The included UV/IR filter passes visible light between 420-685nm at 98% transmission while blocking harmful ultraviolet and infrared wavelengths, protecting the camera sensor and improving image quality. Precision manufacturing ensures minimal focal plane tilt and dust intrusion compared to standard T-rings, making this an essential accessory for serious astrophotographers using Canon EOS cameras.
