How do you draw ray diagram of compound microscope?

To draw an image formed by compound microscope first draw a straight horizontal line (principle axis) now make a lens, take its focal length about 1.5cm at both sides, now at one side draw an object (arrow facing up) but smaller than the lens. make two rays from the tip of the object (arrow head), make one ray strike the lens straight and refract it through that focal length of the lens which is opposite the object, make second ray passing straight through the optical center of the lens and extend both rays, the point at which both rays cut each other make an image arrow vertically straight but up side down from principle axis, an consider this image as an object an make another lens bigger and opposite side of the first lens, now from the arrow head of the image (considered as object) make two rays towards the second lens, first striking straight the lens and again refracting from focal length of other side, second rays passes straight through optical center of lens, extend these rays but from back side, the point at which they coincide make the final image pointing down from the principle axis.
