Skylab ultraviolet stellar astronomy experiment S019.
An objective-prism stellar spectrograph of 15-cm aperture was flown on all three Skylab missions. The wavelength region from 1300 A to 5000 A was covered by a special optical system containing a combination of reflecting telescope optics, a CaF(2) objective prism, and an achromatized field corrector lens system of CaF(2) and LiF. Observations of 188 star fields, each covering 4.0 degrees 5.0 degrees , were conducted at the Skylab antisolar airlock with the aid of an articulated mirror system (AMS) which allowed acquisition within 30 degrees degrees 360 degrees band of the sky.
