SUMMARY
The discussion centers on creating a ray diagram for a Galilean telescope, which utilizes a convex lens as the objective and a concave lens as the eyepiece. The user is confused about how the concave lens affects the image size, noting that it appears smaller. It is established that the image produced by the objective lens is positioned closer to the eyepiece than its focal length, which is crucial for correctly illustrating the enlargement effect in the ray diagram. Properly drawing the ray diagram will demonstrate how the combination of these lenses results in magnification.
