The Cassini Erecting Prism Diagonal increases the viewing comfort and usability of refractor telescopes. True astronomical telescopes will produce an upside down image and with the Cassini Erecting Prism Diagonal the image in your telescope will turn right side up. No erecting lenses, mirrors, or prisms are added and having these elements in the telescope can cause images to be dim and or distorted making terrestrial viewing (land viewing) difficult. The Cassini Erecting Prism Diagonal will turn the image in your telescope right side up to enable easy, comfortable terrestrial viewing. Cassini Prism diagonals consist of a 45-degree prism and are available in 1.25-inch format.
