Observatoires Christoph Keller

Message to the Extraterrestrials, 2007 (floor, left) Dobsonian Telescope with pedestal, slide projection with telescope mounting, slide carrousel with timer A slide projector, attached to a Dobsonian telescope, projects images on the telescope's concave mirror, which in turn reflects them on two further mirrors installed on the ceiling and on the floor, until the light beam leaves the space through a window. The 80 slides show images which have been part on the legendary "Golden Record" produced for the Voyager 1 and Voyager 2 missions.

Formally, use is made of solarised negatives. This technique reverses light and shade values and gives the prints a surrealistic look. The resultant reality shift conveys the impression of an extraterrestrial vision of our scientific "monuments". Photo © Carsten Eisfeld
