Claims

[Claims for Utility Model Registration] 1. In a guide eyepiece to be attached to the eyepiece of an astronomical telescope, the cladding portion at a predetermined location on one side of at least one optical fiber along the long axis is removed to expose the core portion. In this optical fiber for display, a vertical light leakage part to form a vertical pattern and a lateral light leakage part to form a horizontal pattern are respectively formed, and both the light leakage parts are combined orthogonally to each other to form a cross-shaped pattern. A guide eyepiece using an optical fiber, comprising: a light transmitting plate bonded to face the light leakage portion of the optical fiber; and a light source close to one end of the display optical fiber. 2. The guide eyepiece according to claim 1, wherein the water leakage portion of the optical fiber is formed in an intermittent manner. 3. The guide eyepiece according to claim 1, wherein the water leakage portion of the optical fiber is formed continuously.
