Web11. jún 2024 · In a refractor or a reflecting telescope, the focal length start at the aperture (primary mirror or objective lens) and ends at the focuser where the light rays come together. Generally, when looking at a telescope, it’s safe to assume that a long tube means a long focal length and a short tube means a shorter focal length. WebGlue the lenses to the center of the frame. The shorter focal length lens will be the eyepiece. Glue that framed lens to the end of the smaller tube. Glue the other framed lens to the end of the larger tube. 3.

WebBrief recap and conclusion. As we’ve covered, the most basic telescopes contain two lenses, and the reason for that is simple — due to the basic laws of optics, one lens serves to focus the object that is being viewed, and the other one magnifies it and straightens the picture.
