Many recently looked up at the stars to get a glimpse of the spectacular Perseid meteor shower that fell across the night sky on Wednesday evening. Austrian astrophotographer Gerald Rhemann has been gazing up and photographing stunning sky vistas for decades.
“From the beginning I was interested to image distant galaxies, nebula and comets,” Rhemann tells In Sight. “I very quickly noticed that imaging under the light-polluted skies of my backyard in Vienna didn’t lead to photographic success, because those objects are very faint.”
So he began observing places in the Austrian Voralpen (the foothills of the Alps), which has no light pollution and very dark skies.

Rhemann later began frequenting Namibia in southwest Africa to photograph the far southern heavens from the Kalahari Desert, and he built a fully remote-controlled observatory in Eichgraben near his home in Vienna.
Today, cooled CCD-cameras with various filters are used for astrophoto imaging. Long exposure times can last up to several hours, so a precise motorized mount that compensates for the rotation of earth is required.
“My passion over the past three years shifted towards imaging of comets which is one of the biggest challenges in astrophotography,” Rhemann said.
