The DIRN Observatory ist located in the Austrian Alps at a sea level of about 1000 meters. The whole observatory including telescope, main mirror, fork mount, drives, cupola and building as well as the complete observatory software are self-planned and do-it-yourself. As the location is directly neighbouring the Kalkalpen National Park it offers an extraordinary night sky that is nearly absolutely free of any light pollution. There are only very few places all over Europe that have comparable dark nights! The observatory is run privately.
