The 77 cm Schmidt telescope from 1966 at Brorfelde Observatory was originally equipped with photographic film, and an engineer is here showing the film-box, which was then placed behind the locker at the center of the telescope (at the telescope's prime focus)
The Hungaria main-belt asteroid 3309 Brorfelde was discovered at, and named for the observatory. It was its first minor planet discovery. Naming citation was published on 7 September 1987 (M.P.C. 12210).
