What's stopping you diffracting the light?
Surely you could use a diffraction grating (& camera/CCD) to get a spectrograph?
I'm guessing that this is to run on the AstroPi units on the International Space Station so adding a diffraction grating probably isn't that simple.
Could you try to measure light pollution instead? If the ISS flies over an area at night perhaps you can detect the light from cities etc.
