TS Optics 1.25" star diagonal mirror with 90° angle A star diagonal mirror is used for a comfortable viewing position. It offers an upright but mirror reversed image with a high contrast.
The mirror is used on refractors, Schmidt-Cassegrains, Maksutov-Cassegrains and other telescopes with a viewing position at the rear. The diagonal is not suitable for Newtonian telescopes because they do not have enough back focus.
