Also the observatory has a LHIRES III spectrograph. Its spectral resolution can be modified. The standard version uses a grating of 2400 lines/mm, giving a resolution of R=17,000. In combination with the CCD camera SBIG ST7-E, the spectral range is approximately 80A with a scattering of ~ 0.12A/pixel. Included in the spectrograph, is a neon comparison lamp for wavelength calibration of spectra. |
