Limits of Spectroscopy
What is the faintest "source" that can be spectroscopically analysed
via a telescope for fraunhofer lines and elemental composition? I know bright galaxies and quasars produce ample quantities of light for spectroscopy, but surely the multiple stellar make-up of these objects produces meaningless 'noise' at that level... Ta. Abdul Ahad
