“Per aspera ad astra – through hardships to the stars”
Exhibition at Hangar-7: Astrophotography by the Astronomy working group of the “Haus der Natur Salzburg” natural history museum
FROM 14 SEPTEMBER TO 04 December 2016, PHOTOGRAPHERS FROM THE ASTRONOMY WORKING GROUP OF THE “HAUS DER NATUR SALZBURG” NATURE MUSEUM WILL BE EXHIBITING THEIR BEST PICTURES. THE UNUSUAL SHOTS SHOW THE NIGHT SKY IN ALL ITS GLORY AND REVEAL CELESTIAL OBJECTS THAT ARE INVISIBLE TO THE NAKED EYE.
The exhibition covers the entire spectrum of astrophotography. Alongside pictures of the moon, the sun, planets, comets, nebula and galaxies, there will also be some unusual night-time shots that have been taken without a telescope. The result: impressive, colourful pictures of the highest quality that show the observer the beauty and infinite nature of our universe. Some of the objects are so far away from Earth that reaching them in an aeroplane would take 100 times longer than the universe has existed.
The title of the exhibition acknowledges the hard work of the participating photographers. On clear winter nights, temperatures can fall as low as −17 °C – this calls for a great deal of dedication when trying to capture the starlight in spots with as little light pollution as possible.
One of the main differences between an astrophotographer and a “normal” photographer is that, for the former, each photo only represents a small mosaic stone in the overall picture. Many individual pictures with exposure times of up to 20 hours are joined together using software in order to make the fine details of galaxies and nebular structures visible. When attempting to achieve high-quality results, the image noise (and reducing it) is just as important as the darkness of the shots.
Due to the complexity of the process – from choosing the object through to the final picture – astrophotographers can improve continuously and produce better results over the years. The shots created with affordable amateur equipment demonstrate that rookie astronomers can now take pictures which would only have been achievable by observatories up until a few years ago.
As part of the broadcaster ORF’s “Long Night of Museums 2016” (01 October 2016 from 6.00 p.m to 1.00 a.m.), the photographers and their equipment will be available at Hangar-7 to answer questions and demonstrate their passion for astrophotography in person.
About the Astronomy working group
The Astronomy working group of the “Haus der Natur Salzburg” natural history museum was founded in 1979. Since 1988, it has been operating the Salzburg observatory, which has become the gateway to outer space for thousands of people in the city.
Many members of the working group are enthusiastic astrophotographers who will now have the chance to present the results of their passion to a broad audience for the first time.
About the photographers
The exhibition’s organiser, Wolfgang Krispler, is a member of the Astronomy working group of the “Haus der Natur Salzburg”, Astroteam Mariazellerland and PixInsight Austria. He is currently studying astronomy at the University of Lancashire. Wolfgang has been practising astrophotography since 2014 and is especially interested in deep sky photography, which involves taking pictures of objects outside our solar system.
The other photographers, most of whom are also members of the Astronomy working group, are: Rochus Hess, Bernd Wallner, Helmut Kahr, Andreas Max Böckle, Albert Junger, Robert Reischl, Lothar Kurtze and Alexander Krombacher.
From 14 September to 04 December 2016.
