An automatic system for simple astronomical measurements is proposed. It consists of a CCD based webcam, standard photo-lenses and rotating mount with a computer driven step motor. The system is controlled by dedicated user friendly software with an intuitive graphical user interface. It is demonstrated how it can be used to measure light curves of variable stars. The cost of the system is below $200 and it is well suitable for education or for hobby.
