There are many commercial solutions to fit a camera to a microscope, they are expensive, and therefore rarely used by students. Yet the educational impact of a picture they made themselves from their own cells is very different from a picture in a book. However, current digital cameras - preferably the cheap equipped with small goals - and those integrated into their phones often well suited for photos through the microscope or a binocular: just press down the camera lens on the eye and the center. Sharpness at infinity is no other in general.

The main difficulty is to find - And maintain - a position that aligns the optical axes of the microscope and camera. With a little patience we finally see a bright circle in the center.
