Stars of Cassiopeia rise above Teide Observatory of Tenerife, Canary Islands. Note the prominent deep sky object known as the Double Cluster right above dome. The large towers are GREGOR and VTT (partly visible) solar observatories. GREGOR (with the red illuminated dome) is a new type of a solar telescope with an aperture of 1.5m and VTT is another major solar instrument with the primary mirror of 70cm in diameter. The light dome behind the tower is made by the towns on the northern cost of Tenerife island.

    Again, the illuminated dome is GREGOR (a solar telescope with a 1,5 primary mirror). VTT is visible in the background, half covered by the GREGOR building.
