In the southern hemisphere sky we are treated to the stunning sight of the centre of the Galaxy rising each night, as the starfields of Scorpius and Sagittarius come up over the eastern horizon. In this shot, taken last night (May 2/3), we see the Milky Way’s heart rising behind some of the robotic, remotely-controlled domes and telescopes at the Atacama Lodge in Chile. Only the centre dome is operating, taking images or data under the command of someone half a world away.

Amazing technology to be sure, but … that robotic observer misses the experience of standing under the Milky Way, watching its heart rise over the Andes and swing overhead through the night. The Milky Way is so bright it lights the ground, as you can see here.

Last night our little group of 7 Canadian observers had a fantastic time exploring the southern sky with several telescopes, including an 18-inch reflector set up for us by lodge owner Alain Maury. With the help of a couple of wide-angle eyepieces we saw wonderful views of the Vela Supernova Remnant, dark nebulas in the Milky Way, and showpiece targets like Omega Centauri and the Tarantula Nebula – the list goes on! And will again tonight, as we compile another “hit-list” of targets to find tonight.

For this shot, I used the Canon 7D camera, a 15mm lens, and ISO 2500 for a 40 second exposure at f/2.8. This is one of about 500 frames taken for a time-lapse movie of “Galaxyrise.”
