Learning about colours in astro photography

In astrophotography, colours are treated in different ways – telescopes generally do not take colour pictures, but use special filters to capture light in particular parts of the optical spectrum (e.g. red light only). This interactive app from the Faulkes Telescope project will show you how colour images are made using different filters, combining them to make various types of “colour image”.
