Tele Vue 1.25" 90 Degree Everbrite Mirror Star Diagonal - DPC-1250

The Tele Vue 1.25" 90° Everbrite Mirror Star Diagonal is one of the best additions to your telescope equipment you will make! This Star Diagonal will fit into any standard 1.25" eyepiece barrel. It will allow you to view through your scope at a comfortable 90° angle to the pointing axis, a very important feature when you are looking at objects close to the Zenith. Save neck and back strain.

Whiter and brighter images. Simply put, that is the benefit of the Tele Vue Everbrite mirror coating. This exotic, dielectric, nonmetallic coating is 99% reflective across the full visual spectrum, resulting in the "whitest," and most natural image available. The coating is painstakingly applied to Pyrex, with a surface accuracy of 1/10 wave flatness. A superior flat mirror is what you want when you need to obtain the best optical image performance from your telescope system!

The diagonal body is machined from a solid block of aluminum. In this way you can be sure of getting permanent alignment. The one piece body construction also assures heavy accessories can't force the diagonal body to "unscrew" from the barrel as with other brands. Features brass compression clamp, anti-reflection threads, and 1.25" filter threads.
