Teleiconograph, a combination of the telescope and camera. The principle is that of allowing the image transmitted by the object glass of a telescope to pass through a prism connected with the eye piece. The rays of light that would in the ordinary use of the telescope be transmitted direct to the eye are refracted by the prism, and thrown down on a table placed below the eye piece.
