While astronomers get ready to observe with ESO s Very Large Telescope, Nature prepares for her own grand display. As night falls over the desert, the southern sky reveals its nocturnal beauty, leaving the spectator in silent amazement. Some people, however, don t just stare at the spectacle. With great skill, they record these unique moments for everyone to see they are the photographers of the night. Anyone who has been up at night in a remote, high place such as at one of ESO s observatories in Chile may have been lucky enough to experience the splendid view of the myriad of stars shining brightly from the heavens. It is a both a dream and a challenge for a photographer to capture an image of this incredible view. Yuri Beletsky is an ESO Fellow and astronomer at the Paranal Observatory. When not observing with the world s most advanced telescope, the VLT, he actively lives out his passion for taking pictures of the southern sky. Over time, Yuri has produced many spectacular images of Paranal against the wonderful backdrop of the night sky. A laser beam shooting out of one of the VLT s Unit Telescopes. The bright constellation of the Southern Cross. The Pipe Nebula with its picturesque dust lane crossing the Milky Way. Sunlight reflected by small particles of dust lying in between the planets causes the faint zodiacal light. Paranal is an ideal site for astrophotographers as it offers crystal-clear, extremely dark skies with perfect weather conditions on about 320 nights per year. Gerhard H depohl, an electronic engineer at Paranal, knows about the photographic benefits of the VLT s site. My favourite type of photography is landscape photography and in particular images of the landscape at night, showing the Milky Way in the night sky here in the Atacama desert. And here at Paranal I can have the telescopes as a nice foreground and the stars and the night sky as a background The bright plane of our Milky Way as it arches above the VLT. An image like this can only be obtained under top-notch stargazing conditions, such as those offered at Paranal. Astrophotography is very demanding. The photographer has to stay out in the dark and in the chill of the night for many hours. Sometimes it can take several nights of painstaking work in these tough conditions to obtain just one image and the equipment must always function flawlessly. phane Guisard is the head of the optical group at Paranal. His astrophotography benefits from his professional expertise as an optical engineer specialising in telescopes. I take pictures of galaxies and nebulae with a telescope, but I also like to take wide-field images of the sky with a terrestrial foreground. I like to share the beauty of the sky and the Universe. This photographic mosaic of the central parts of our galactic home is just one example of St phane s work. Taken with an amateur telescope coupled to a CCD camera, the image combines about 1200 photos for a total exposure time of around 250 hours. phane has also produced a spectacular series of timelapse sequences at the Paranal site. Producing such sequences is quite a challenge as the images must be taken at regular intervals, and all the parameters must match perfectly to obtain the sensation of the moving firmament. There is no doubt that Yuri, Gerhard and St phane will continue to produce stunning images of the starry skies above Paranal. The wonderful quality of the images is a testament to the splendour of the night sky at ESO s Paranal Observatory. By sharing their work, these three astrophotographers have brought their magnificent view of the southern sky to a wider audience. This is Dr J signing off for the ESOcast.
