Description

The Lumicon 1.25" Enhanced Aluminum Diagonal reflects 96 to 97 percent of the light from the telescope's primary optics directly into your eyepiece. Its single 1/8 wave precision-polished surface is superior to the three surfaces of prism diagonals. Lumicon collimates each diagonal mirror via a double-pass collimator, ensuring that the light reflected from the diagonal is perfectly perpendicular to the telescope's optical axis. The telescope-side of all of Lumicon's diagonals are threaded for filters, so you can switch eyepieces while leaving your favorite Lumicon filter in place.

The Lumicon 2" Enhanced Aluminum Diagonal reflects 96 to 97 percent of the light from the telescope's primary optics directly into your eyepiece. Its single 1/8 wave precision-polished surface is superior to the three surfaces of prism diagonals.

Lumicon collimates each diagonal mirror via a double-pass collimator, ensuring that the light reflected from the diagonal is perfectly perpendicular to the telescope's optical axis. The telescope-side of all of Lumicon's 2" Enhanced Aluminum Diagonals are threaded for 2"/48mm filters, so you can switch eyepieces while leaving your favorite Lumicon filter in place. Includes 2" to 1.25" reducer.
