Prisms & Star Diagonals for Telescopes
A prism or star diagonal makes observing more comfortable by changing the viewing angle and, depending on the design, the orientation of the image. In this category you will find 1.25-inch and 2-inch star diagonals, Amici prisms and practical solutions for visual observing and nature viewing. Pay attention to the connection size, the required image orientation and the optical quality. A well-made diagonal with a secure ring clamp keeps the eyepiece firmly in place and provides a bright, high-contrast image.
