iOptron 2" Dielectric Coated Mirror Star Diagonal W/1.25" Adapter
This is an iOptron 2" Dielectric Coated Mirror Star Diagonal. This diagonal uses a mirror to fold the beam from your telescope. This mirror is extremely flat and is coated with a dielectric material for high transmission of light. The diagonal eyepiece barrel is made to accept 2" standard astronomical eyepieces, and it has an adapter to permit the use of 1.25" eyepieces as well.
NOTE: The photo shows a generic iOptron star diagonal; your product may look slightly different due to continuing upgrades and improved designs from iOptron.
