T-2 BBHS Star Diagonal

The T-2 BBHS Star Diagonal offers superior optical performance with its Broadband Hardsilver (BBHS) coating, delivering the highest reflectance over a wide spectral range from 390 to 2000nm. Unlike cheaper dielectric coatings, BBHS provides exceptional brilliance and light transmission. This star diagonal is equipped with Sitall zenith mirrors on both sides and features T-2 Photo threads for optimal compatibility with various telescope systems.
