| Abstract: | The scientific interest in observing the 900–1200 Å spectral range is based on the fact that this spectral region contains the bulk of the accessible emission of hot objects (T ∼ 105–106 K) and the majority of the resonance lines of many astrophysically important atoms and ions. To pursue the pioneering work with Copernicus on bright objects in that spectral range, a high spectral resolution of 3 104 should be attained. In addition, to have access to extragalactic targets (i.e. increase the cosmological return of this observatory) a large collecting area is needed. A design based on the use of 1m class grazing incidence telescope is now under study. Instrumentation at its focal plane may include a 3 104 resolution spectrograph in the 900–1200 Å spectral range, a 103 resolution spectrograph in the 100–300 Å spectral region and a 104 resolution spectrograph in the 1200–2000 Å region. |
