Why do comets always look green in photos?
«

Just been watching the BBC's monthly 'Sky at Night' programme on iPlayer and they were talking about a comet that is now visible with a low-powered telescope or even binoculars. One of the show's presenters helpfully gave us some tips on how to take photographic images of the comet, but also stated that the photos showed the comet's trailing gasses to have a green tint, whereas the naked eye looking through a telescope can't pick that up.
