Images taken with EIT at different wavelengths from 24 April 2014. The device is sensitive to these four wavelengths. EIT is built as a single telescope with a quadrant structure to the entrance mirrors: each quadrant reflects a different colour of EUV light, and the wavelength to be observed is selected by a shutter that blocks light from all but the desired quadrant of the main telescope.
