Merate Astronomical Observatory is an old observatory in Merate (Lecco), Italy. It is the location of a 1 meter Zeiss telescope since 1926. The same type of Zeiss telescope had been installed at Hamburg-Bergedorf Observatory, and the Royal Observatory of Belgium. [1] The Zeiss di Merate was a reflecting telescope on a equatorial mount, and was one of the largest telescope funded by the Regno d'Italia ("Kingdom of Italy") before Italy became republic in 1946.
