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)...
