Aerial view of the surroundings of the solar magnetograph. There is a dome of the 2-meter telescope at the bottom left of the picture, a dome of the 0.65-meter telescope in the middle, the building with the HSFA-1 horizontal telescope and the solar magnetograph to the left and up from the centre, the building with HSFA-2 and a spectrograph to the right and up from the centre. |
 |
Aerial view from a different angle. The building with the solar magnetograph is close to the upper left corner of the picture. |
 |
The actual building of the solar magnetograph (view from the east). You can see the dome of the coelostat on the left; the building with the control section is hidden behind the trees on the right. Both buildings are connected by a lightconducting tunnel. |
 |
A view from the west. Dome of the coelostat is removed.

A view through the tunnel from the coelostat to the control room. The objective mirror of the horizontal telescope can be clearly seen on the left side. There is an occulter with a slit on the right. You can see a reflection of the primary and secondary mirror in the objective.
