The mirror star diagonal provides comfortable viewing when observing astronomically with refractors, Schmidt-Cassegrains or Maksutovs. Only Newtonian telescopes have no need of this accessory.
The particularly high-quality zenith mirror with dielectric coating offers 99% reflection. Equipped with a gentle ring clamp and T2 thread.
Test reports confirm that the new zenith mirror offers a quality of at least 92% Strehl (at least 1/10 Lambda p-v surface) over the entire surface, making it very interesting for demanding observers. The mirror coating even exceeds 99% reflection (400 - 700 nm) in many areas, so you don't have to worry about any loss of light.
All housing parts are made of solid metal to ensure optimum stability of the deflection optics and connected accessories.
