M16 Eagle Nebula
Featured in the Sky At Night October Edition
This is M16 captured from ICAstronomy in Oria, Spain.
The image was captured using narrowband filters (Ha, OII, SII).
Also in the image is the famous Pillars of Creation.
Ha 10x1800 Secs
OIII 7x1800 Secs
SII 9x1800 Secs
13 Hours in total.
The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is cataloged as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula in the northeastern part is approximately 9.5 light-years or about 90 trillion kilometers long.
The cluster associated with the nebula has approximately 8100 stars, which are mostly concentrated in a gap in the molecular cloud to the north-west of the Pillars. The brightest star (HD 168076) has an apparent magnitude of +8.24, easily visible with good binoculars. It is actually a binary star formed of an O3.5V star plus an O7.5V companion. This star has a mass of roughly 80 solar masses and a luminosity up to 1 million times that of the Sun. The cluster's age has been estimated to be 1–2 million years.
The descriptive names reflect impressions of the shape of the central pillar rising from the southeast into the central luminous area. The name "Star Queen Nebula" was introduced by Robert Burnham, Jr., reflecting his characterization of the central pillar as the Star Queen shown in silhouette.
