SKYWATCHER DIAGONALS

SkyWatcher 45° & 90° Star diagonals are incredibly useful accessories for refractors and Schmidt-Cassegrain telescopes allowing for comfortable positioning when viewing objects towards zenith.

The SkyWatcher 2" 90° Dielectric Star Diagonal is a high performance diagonal for high-end telescopes. The high reflectivity of the mirror (99%) offer a bright image without losing luminosity. The high optical correction of the mirror (1/10 lambda) does not compromise the resolution or the contrast of the image.
