                  The TS Optics Diagonal Mirror 90° 1.25" is a premium star diagonal designed for astronomers who demand high image quality and reliable mechanical performance. Unlike many standard diagonals with lower reflectivity and plastic construction, this model features a 99% dielectric-coated mirror, precision 1/12 Lambda optical surface, and a robust CNC-machined metal body. The design ensures full 1.25" field illumination without vignetting and includes a brass compression ring for secure and gentle eyepiece holding.
