AZ800 placed in a nature park
Look at the stars in Zeutschach, Austria’s largest private observatory in 2017 is located in the Zirbitzkogel-Grebenzen Nature Park – in “dirt-free” air: In Zeutschach, at 1.050 meters above sea level, our Customer from vienna has made his dream of astronomy come true. The observatory is also open to the public.
