This spectrum (taken using the C11 and  ALPY600 spectrograph) is of magnitude 15 star IRAS 00500+6713 in Cassiopeia. It is believed to be the result of a merger between two white dwarfs, kept from complete collapse by a powerful magnetic field and may be the stellar remnant of the supernova seen by Chinese astronomers in 1181.  It is a star of extremes with a temperature of 200,000 K and 16,000 km/s winds. More about this star and references on my BAA page here
