The Jellyfish nebula (IC443) is the name given to a galactic supernova remnant situated in the constellation Gemini about 5000 light years from Earth. The remains of a supernova that exploded prior to the dawn of the Julian and Gregorian calendars is coincidentally bookended by two bright stars in the frame, Eta Geminorum aka Propus/Praepus/Tejat Prior on the right and Mu Geminorum aka Tejat/Calx on the left side.
The narrowfield framing shows the partial shell of supernova remnant…
