Vacuum Tower Telescope (VTT), Teide Observatory (Tenerife, Spain)

This Wednesday I had a chance to assist an observation at the famous VTT (with E.Khomenko and M.Collados). The telescope is one of the most productive instruments in solar physics. The diameter of the primary mirror is 700 mm. The left picture shows the heliostat - it follows the Sun during the day and directs the light into the telescope. The right one shows the tower from the ground. It's an 11-storeys building!

It was a lot of fun to be there. Can't wait the next opportunity!
