D. spectroscope
A spectroscope (or spectrograph) disperses starlight into its component wavelengths, showing the bands of colors and the emission/absorption lines used to determine composition, temperature, velocity, etc. A reflecting telescope collects light but a spectroscope analyzes its spectral bands.
