This tutorial features a set of 105 science images of the High Amplitude Delta Scuti (HADS) star FS CMi. HADS stars belong to the Delta Scuti class of variable stars. They are characterized by high amplitude brightness variations caused by pulsations in the star. Brightness variations typically occur on timescales of a few hours.
