iOptron 1.25-Inch Dielectric Coated Mirror Diagonal

iOptron’s 90-degree dielectric star diagonal helps to keep your head in a comfortable viewing position when your OTA is aimed at or near the zenith. Fitted with a dieletric hard-coated BK-7 glass mirror, the diagonal transmits more than 99% of the incoming light to provide you bright, high-contrast, clear images while maintaining extremely high resolution.

This diagonal’s 1.25″ barrel and eyepiece holder are compatible with the most popular size focusers, drawtubes, and accessories. An internal, integrated safety stop in the eyepiece holder protects the mirror, ensuring a long life. The diagonal is machined from an aluminum housing with black anodized finish, making it super durable and lightweight.
