Today I was photographing the MAGIC when I saw a big crane beside the William Herschel Telescope. Of course I went up to look, and found the engineers were winching the dome shutter back into position after repairs.

Of course it took some time. As you can see in the last photo, the motor is pretty big and heavy. I don’t know what the shutter weighs, but the rotating part of the dome is 120 tons.
