The Baader 2" BBHS Sitall Mirror Adjustable Star Diagonal features a Sitall ceramic mirror coated with proprietary Broadband Hard Silver (BBHS) technology sealed with dielectric layers to achieve 99% reflectivity across the 390-2000nm spectral range. The ClickLock eyepiece holder uses 3-point clamping with a simple 20° twist for secure, non-marking retention of 2" eyepieces, making it ideal for high-power planetary viewing and deep-sky observation. The diagonal body integrates directly with 2" telescope connections and can be threaded to SCTs with an optional Baader lock ring, while the removable ClickLock holder and nosepiece expose 2"x24tpi threads for full modular T-2 system compatibility.
