Recently I observed profiles of hydrogen Balmer lines in Sirius spectrum with spectral type A. I used LowSpec spectrograph with 1800 l/mm diffraction grating and APO APM 107/700 on HEQ5 mount. H-alpha: H-beta: H-gamma: H-delta & H-epsilon: I had some problems with stacking, so I used the best single frames in analysis.
