摘要
A finder or sighting scope for use with an astronomical telescope, the finder scope having a target member or reticle located at the common focus of the scope objective and the eyepiece. The target member or reticle may be seen as a magnified telescope view when viewed through the eyepiece and as a target or star image against the backdrop of the sky as viewed by a naked eye, the target or star image being projected into the viewer's line of sight by the objective and a mirror and beamsplitter.
