The mirror in this 2-inch diagonal has undergone a high-reflectivity multi-coating process that enables it to reflect 99% of the gathered starlight for exceptional brightness and contrast (regular diagonals typically reflect 90-95% of light).

Includes 2"-1.25" adapter with non-marring compression-ring eyepiece clamp.

Tapered nosepiece for a secure fit.

Threaded for 2" filters. 

NB.  Please check out my other items as we are also selling the scope and polar mount.
