Notes

NGC 2174 is a faint emission nebula in Orion, lying north of the Hunter’s club and only about 2.5 arc-minutes from the third magnitude star Eta Geminorum. Embedded within the nebula is the open cluster NGC 2175, an association of approximately 60 stars lying at a distance of 6350 light years from Earth. The brightest star in the open cluster, O-type SAO 78049 at Vm=7.55 is responsible for exciting the gas in the nebula and giving us our view of this beautiful celestial object. This star can be seen at a 7 o'clock position just below the bright "knot" near the center of the nebula.
