The light of the stars carries information to us from unimaginably great distances. Spectroscopy, i.e. the qualitative evaluation of this light, is the key that opens the door to the composition, temperature, speed, and other state variables of the distant light sources.

Even as amateurs, we can analyze starlight with relatively simple means. On a modest scale, it is even possible to collect and evaluate data that can be used by professionals.

Here we want to present our spectroscopic activities.
