... On the coude focus of 1-m (Zeiss-1000) telescope have installed two echelle spectrometers: CEGS and HELEN. Both spectrometers have been designed by Musaev F.A. and oriented for spectroscopy of relatively bright stars with different spectral resolution. ... spectral resolution R~40000, range 3200 - 10100 Angstroms - registered simultaneously with 1242x1152 CCD (see example of CCD image of Solar spectrum, obtained with 1252x1152 CCD - about 100 spectral orders are seen (151Kb jpeg file ). ...
