  The Multi-adaptive optics Imaging CamerA for Deep Observations (MICADO) will
image a field of view of nearly 1 arcminute at the diffraction limit of the
Extremely Large Telescope (ELT), making use of the adaptive optics correction
provided by single-conjugate adaptive optics (SCAO) and multi-conjugate
adaptive optics (MCAO). Its simple and robust design will yield an
unprecedented combination of sensitivity and resolution across the field. This
article outlines the characteristics of the observing modes offered and
illustrates each of them with an astrophysical application. Potential users can
explore their own ideas using the data simulator ScopeSim.
