Product description

A high grade star diagonal mirror with a very precise mirror surface (approx. 1/12 lambda) for demanding users.

99% reflectivity means more light and thus a brighter image. At the same time the dielectric coating is very strong and protects the mirror surface.

2″ Star Diagonals offer a larger possible field of view compared with 1.25″ diagonals. This is particularly important for deep sky observing through Schmidt-Cassegrains and Maksutovs with their rather long focal length.

The diagonal screws directly onto the SC thread at the rear of the telescope.

Suitable for all telescopes with an SC thread.

TS Optics is a brand of Teleskop-Service.
