Currently Playing: Foucault movie of a parabolic mirror F/4.2 (200 micron movement steps, very short video)

This is a video that consists of the Foucault images of the first telescope mirror that I made. It has a diameter of 10" (255mm). The mirror is an F/4.2 and the distance steps between the image frames are 0.2mm.
