(Up): Both domes of 120-cm (foreground) and 193-cm (background) telescopes at Observatoire de Haute Provence, with stars trailing in the western sky, during a long exposure.
(Bottom): both stars HD 80606 (right) and HD 80607 (left) observed together during the transit night, with the 120-cm telescope and camera.

The peculiar configuration of the extrasolar system HD80606; the transit observed on 14 February corresponds to the planet crossing the stellar disk, at a distance of 0.29 times the Earth-Sun distance.
