6: Control room of NOT

Stars above NOT

NOT with the North Star behind. NOT was pretty far ahead with innovation in the technology. Do you see the gaps under the dome? They were there to get a better thermal stability in the local atmosphere. The entire building rotates when the telescope is rotated into various positions. This is to optimize the length of the cable between the telescope and control room and avoid sliding contacts.

Control room NOT

Computers already existed in the 1990s and many such were needed to control all measurement systems. Telescope control was done by a program developed in Pascal, ANSI C. The operating system used in the academical world is UNIX. He who developed the program came down a couple of days and I had time to talk a lot with him. He traveled around the world in different observatories, most exciting seemed to be at the visits on Spetsbergen, rifle (polar bears) in one hand and instruments in the other!

Hale Boop data

The French people inspect the data of Hale Bopp, they was able to see the comet core's rotation, or let say the trace of it in the dust.
