Comet Wirtanen and Pleiades above the tree
Finally comet 46P/Wirtanen is large and bright enough to show up in a nightscape style image. It is also visible to the naked eye form a dark sky location and looks like a diffuse star cluster. Hope you can catch it before the Moon becomes too bright this month.

The Observatories

in June 2011 I was very lucky to attend the inaugural STARMUS festival on Tenerife and observe with the largest single-mirror optical telescope on the planet – 10-metre GranTeCan. After spending five days at STARMUS listening to and chatting with the great astrophysicists and space legends I decided to dedicate more time to astronomy science and film the observatories around the world.

Liquid Light Show

During our camping holiday at Wilsons Promontory National Park (Victoria, Australia) in December I noticed a glimpse of bioluminescence in the surf. However, the weather was not favourable for night sky photography and I knew I had to return at the earliest opportunity and photograph this phenomenon under the stars. I waited for the next New Moon in January 2013 and ventured out to Squeaky Beach at night. The blue surf started to appear when it became dark and it was amazing to see the blue sparkle as I walked in the water.

Persistent Meteor Trains
