♦ High-quality CNC body

♦ Compression ring for 2" accessories

♦ Adapter for 1.25" accessories also with compression ring

♦ Very precise mirror surface with 1/12 lambda

♦ Fused quartz mirror substrate - comparable to Zerodur or Sital

♦ Maximale illumination of 2" eyepieces

♦ Thread for 2" filters at the 2" barrel and at the 1.25" adapter


 

TS Optics 2" Star Diagonal Mirror with 99% reflection and CNC body.

The 2" star diagonal is coated with the same aluminium layers as high-quality telescope mirrors. We achieve a maximum reflection of 99%, and like a telescope mirror, the coating is protected from ageing by a quartz layer. The quality of the mirror is maintained even after many years.
 

The mirrors substrate is fused quartz, comparable to Zerodur or Sital

If you want an absolut high-end star diagonal, with excellent planarity and reflectivity, then the star diagonal with the quartz substrate is the right one. Fused silica mirrors offer a higher thermal stability and have no bothersome expansion effects through temperature differences.
 

Further advantages and features of this TS star diagonal mirror:

♦ High-quality CNC body completely made of metal
♦ 2" barrel without safety notch - no jamming possible - the mirror harmonizes perfectly with compression rings
♦ 2" and 1.25" accessories are gently and precisely clamped by compression rings
♦ Thread for 2" filters at the 2" barrel and at the reduction adapter for 1.25" accessories
♦ Maximal illumination - even extreme 2" wide angle eyepieces can be used to the full
♦ High-quality mirror with precise surface and 99% reflection - when observing, you will not notice any difference in brightness and sharpness, compared to direct vision
