     Diagonal Mirror Omegon 90° 1.25″ 45.15 €

The 2“ Omegon star diagonal's mirror is coated with a very thin layer of vacuum deposited aluminium in order to guarantee a maximum reflection of 99% with the highest contrast and optimal sharpness. The residual stress in the plane mirror which can occur with the dielectric vapour deposition process is ruled out here.


Beside eyepieces, a star diagonal is one of the most important accessories. What is the use of a good objective or the best eyepiece if the star diagonal is inferior? We recommend the Omegon 2“ star diagonal without reservation to everyone, including those working with high end instruments. The star diagonal permits full illumination of 2” wide field eyepieces.


Included in delivery:

  • 2“ star diagonal with 99% reflection
  • reducing adapter, from 2“ to 1.25”
This star diagonal gives 99% reflection, and so provides a much brighter image than with an ordinary star diagonal.
