Milky Way over Roan Jase

Milky Way over Roan Jase

I went to Roan Jase for a night to do some astrophotography with Julien and Jorge. Conditions were really good, though pretty savagely cold in late autumn, 1000m above sea level.

Trying to get an equatorial mount aligned is tricky. It would be easy enough in the northern hemisphere, where there’s a nice bright star near the celestial pole to target, but in the south there’s no bright pole star and we struggled to get the telescope well aligned. Shining the laser through the guide scope to see where we were pointing was our best technique.

The finest sight of the southern skies. Us poor natives of the northern hemisphere are seriously deprived, restricted to seeing some crappy outer spiral arm of the galaxy while the lucky folk of the south get to look towards the centre.

The Milky Way is at the right, and the Milky Way’s two satellite galaxies, the Magellanic Clouds, are in the middle of this photograph. There was a lot of airglow to the south west, and just to the right of the Large Magellanic Cloud you can see the distant glow from the town of Taltal.

The beautiful southern Milky Way, shining brightly over the four telescopes of the VLT, and the VST in the distance.

The Milky Way crosses the sky over two of the Auxiliary Telescopes. The sky looked pretty dark to the naked eye but in the long exposure it turned out to be full of strong red airglow. Around sunset, there are usually lots of satellites visible crossing the sky, and a few can be seen in this photo.

In the late evening twilight just before the start of proper darkness, the centre of the galaxy rises behind UT4.


Turn the lights out!

The centre of the galaxy passes right over Paranal. We take great care to avoid stray light that could affect our observations, but this photo contains damning evidence – someone left the lights on in the VLTI control room.
