Without rings, you have to refocus after each eyepiece change, which takes time and disrupts the image. With the rings, you set these differences once.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The set includes three 5mm thick aluminum rings. You place them between the eyepiece or camera and the focus adapter, and secure them with two set screws at 120 degrees.
