1 2. Other way round – we know the chemical composition (and also rotation curves and distance) of galaxies because we have very, very accurate colour images. And the telescopes don’t have to be particularly powerful for nearby galaxies, you can get a good shot of Andromeda with a basic SLR camera. The Geoff.
