Prisms, 90 Degree Diagonal Mirrors, Erecting Eyepieces
Telescopes and eyepieces display a mirror image. This phenomenon is present in every telescope. As a result, left and right are reversed and the image is turned upside down. You can use a prism, a 90 degree erecting prism as well as an erecting eyepiece to restore the image to its original condition. This way, you will be able to observe more comfortably!
