Cima Ekar Observing Station, Astronomical observatory in Asiago, Italy.

Cima Ekar Observing Station is an astronomical observatory on Mount Ekar that operates multiple telescopes for studying the night sky and distant celestial objects. The facility provides equipment and infrastructure for researchers to conduct detailed observations and gather astronomical data.

The station was established in 1973 as an extension of the Padua Observatory, bringing advanced research capabilities to the mountain location. Over the decades, it became a center for discovery and contributed to finding numerous celestial objects.

The 182-cm reflector was named Copernico because its completion fell in the 500th anniversary year of Nicolaus Copernicus's birth, a tribute chosen by the University of Padua. Since 15 November 1997 the station has been dedicated to the memory of Leonida Rosino, the astronomer who proposed building a second observatory at Asiago.

The station stands on the crest of Cima Ekar at 1,366 m, about 4 km southeast of Asiago and roughly 350 m above the town. The road climbs from Asiago to the ridge; the site is an annex of the Asiago Astrophysical Observatory and carries observation code 098. Weather at this altitude can affect observations, so check forecasts before setting out.

The 182-cm Copernicus telescope's parabolic primary mirror was figured over about two years by Grubb Parsons of Newcastle, then shipped to the Royal Observatory at Herstmonceux Castle for aluminising before travelling by sea to Asiago. Its first photograph, of the Orion Nebula (M42), was taken on the night of 8 March 1973, three months before the official inauguration.
