Recently, I stumbled upon a film from 1977/1987 created by Dick Hoogenraad (who worked at ASTRON, then Stichting Radiostraling van Zon en Melkweg) and Peter Veen. It contains some nice views of the Dwingeloo Telescope, the Westerbork Synthesis Radio Telescope and the ASTRON building in 1977.
The film was digitized by Drents Audio Visueel Archief, part of Drents Archief.
Bonus points for anyone who can recognize current or past ASTRON employees.
