This 23 mm Stellarvue Crosshair Reticle Finder Eyepiece has a 50-degree field of view, is fully multi-coated, and includes a crosshair reticle that will accept an optional illuminator. This crosshair eyepiece is very high in contrast and has 18 mm of eye relief.

The Stellarvue Crosshair Reticle Finder Eyepiece will work with all Stellarvue finders made to accept 1.25" eyepieces, but it will not work with the older F5 finderscopes without rotating backs.
