Thomas Ruff's "Sterne: 1h 55m/–30º" from 1989 is a C-type color photograph that captures a celestial subject, with its coordinates embedded in the title indicating specific astronomical coordinates. The work demonstrates Ruff's systematic approach to photography, treating the night sky with the same documentary precision he applies to his other subjects, presenting the cosmos as a neutral, observable phenomenon rather than a romanticized vision. Printed on glossy Fujicolour paper, the photograph's modest dimensions and straightforward presentation emphasize the conceptual framework underlying the work, where cataloging and scientific description become as important as visual representation.
