English: An experiment on Gemini X to obtain spectra of bright stars in the southern Milky Way required this ultraviolet lens. The use of a special lens, prism, grating, and film type allowed only ultraviolet light to be recorded. The experiment resulted in only a few usable frames. Picture taken at the National Air and Space Museum's Steven F. Udvar-Hazy Center in Chantilly, Virginia, USA.
