Description: 27mm Kellner Single X Reticle Eyepiece This reticle eyepiece has a single cross hair that can be focused. The single cross hair is useful when collimating Schmidt-Cassegrain Telescopes (SCT) and for visual guiding during astrophotography. When collimating a SCT using the star method, it is imperative that the alignment star remains centered in the eyepiece field. The single cross hair makes it easy to determine the position of the star and helps to ensure a perfect collimation. Upgrade the eyepiece in your finder scope with this reticle eyepiece!
