Merate Astronomical Observatory is an old observatory in Merate, Italy. It has housed a 1-meter Zeiss telescope since 1926.
This Zeiss di Merate is a reflecting telescope on an equatorial mount and is one of the largest telescopes funded by the Regno d'Italia before Italy became republic in 1946.
The same type of Zeiss telescope was also installed at the Hamburg-Bergedorf Observatory and the Royal Observatory of Belgium.
