The <color blue>blue</color> and <color red>red</color> spectra were taken with the grating exhibiting 900 lines/mm and 200 lines/mm, respectively. The spectral resolution in the <color red>red</color> spectrum should be higher by a factor of seven. ==== Alkaid ==== {{ost:spektrograph:spectra:alkaid_comp.png}} ==== Betelgeuse ==== {{ost:spektrograph:spectra:beteigeuze_comp.png}} ==== Delta Orionis ==== {{ost:spektrograph:spectra:delta_ori_comp.png}} en/ost/spektrograph/aufnahmen.txt Last modified: 2019/01/08 13:58by maxpri
