SZ Mon: very low resolution spectroscopy (experiment) [Observed: 16, 30 Oct, 24, 28 Dec 2006, 12, 13 Jan 2007]
I observed this pulsating supergiant with a slitless 100groves/mm transmission grating, trying to see the variations of the spectra as a function of the pulsational phase.

SS433 was observed with a 20cm telescope, a 100 groves/mm slitless transmission grating and a CCD camera. The famous Doppler shifted Halpha lines did not show up clearly with this amateur setup.
