Zagreb Observatory

The old Zeiss 130/1950 mm telescope has been mounted in parallel and will, after the acquisition of the needed equipment, be used to photograph the Sun in the Hα line.

The premises in Popov Toranj were provided by the city government, which gave the funds for the reconstruction and the installation of an astronomic dome and a telescope.

The international renown of the first observatory in the region was enhanced by August Kopff, an astronomer from Heidelberg.

[1] It has always been used primarily for popular science, which flourished in the mid-20th century, when the Esperanto editions of the Observatory spread its name around the world.

The Observatory and the Croatian Astronomic Society made their greatest cultural contribution to Zagreb when they procured the planetarium in 1963.

It traditionally holds lectures, stargazing sessions, astronomic education and other activities for the citizens.
