Improvement of the low-dispersion spectroscopy at Rozhen NAO
Abstract
The paper presents the ideas for improvement of the equipment for the low-dispersion spectroscopy at Rozhen NAO (National Astronomical Observatory) and their realizations. The design and tests of the new slit unit revealed that it allows increasing 2.2 times the observed spectral range, substantially shortens the time for positioning, increases the quality of the spectra, allows for automatic change of observed spectral range. On the other hand the new grism for the red channel of the 2-channel focal reducer FoReRo2 would give considerable increase of the spectral resolution. The higher time efficiency as well as the higher quality of the spectra are sure prerequisites for the successful solution of more astronomical tasks based on observations in this mode.
