Extract
During the flight of the spaceship ‘Salyut’, manned by the spacemen G. T. Dobrovolsky, V. N. Volkov, and V. I. Patsaev, nine spectrograms of α Lyra and six spectrograms of β Cen were obtained with the help of the ‘Orion’ system, in the range of wavelengths 2000–3800 Å and with a spectral resolution of about 5 Å near 2600 Å.
The ‘Orion’ system is a telescope of the Mersenn system, with a large mirror of 280 mm diameter, and a slitless spectrograph of the Wadsworth system with a diffraction grating (Figure 1). The dispersion is 32 Å mm-1. The spectrograms were recorded on a perforated photographic film, 16 mm wide, covered with emulsion of the UFSH-4 type.
