OBJECT DESCRIPTION AND IMAGE SESSION
More than 2
degrees east from the well known Eta Carina Nebula lies a small and
probably more distant nebula: NGC 3503. A small emission nebula with
a dim reflection halo probably ionized by the central group of stars.
It lies in a rich star field crossed by large areas of
HII. There are not much photographs over this object. It is clear
overwhelmed by its closer neighbour the Eta Carina Nebula.
