The mirror inside this 1.25" diagonal has undergone a special high-reflectivity multi-coating process, allowing them to reflect 99% of the precious gathered starlight, providing exceptional brightness and contrast. (Standard diagonals typically reflect 90-95% of light). Housed in high quality aluminium bodies these superb diagonals are a significant improvement over the standard ones supplied with many Telescopes.
