Right, thank you.
I know that i can calculate the radius with the lensemakers formula, but like you said - not important :p
But what is it that provides the sharp image? Why is it that when i look at on object close by (2 m) i need to increase the distance between the lenses (more than 35...
Wauv, thanks for quick answer and the welcome ;)
Sorry about that - Both lenses are double-convex. (the radius of the sphere is not known)
About the ray tracing - My question was more reagarding the theoretical explanation of the lights path through my spyglass. Actualy my assignment is to "1)...

This is my first time posting here, so bare with me. I am from Denmark and I am at my final year of what corresponds to Senior High School. I am currently working on a project about "optical instruments" in physics (I was told that our A level corresponded to your applied physics level)...
