Because i have to start with something, for my first spectrum i chose a very bright star, Vega (Alpha Lyrae), the brightest star in the Lyra constellation.

Even if the resolution is not very high, we can see the Balmer series spectral lines for the hydrogen atom (Hꭤ à Hε). Theses lines corresponding to the transitions from quantum states to the state of level n = 2.
