Reverse galilean telescope

  1. Jun 26, 2003 #1
    This is not a homework question but I am posting it here because I think it may be too basic for the other forums. I am looking for a ray diagram for a reverse galilean telescope (ie. + eyepiece, - objective, so image is minified). Can anyone describe what the ray diagram would look like or direct me to a textbook or webpage which might have a good explanation/diagram? I know the ray diagram for a regular galilean (- eyepiece, + objective) but can't seem to draw it for the lenses being reversed. THank you!

    Hi reverse,
    I don't see what's so difficult about this. Can't you just use the same drawing, with light direction reversed?
