Description

An HII emission nebula in Cassiopeia with a confused identity crisis. It was in Stewart Sharpless's 1953 catalog as an emission nebula, but dropped from his second catalog as it was then believed to be a planetary nebula.  More recently it has been confirmed that it is NOT a planetary nebula.  It is 164 arc seconds in diameter.  It is estimated to be around 4,000 light years away, and around 3 light years across.
