The Eagle nebula (M16/NGC6611) in the constellation Serpens imaged through narrowband filters using an 8" SCT (at the native 2032mm focal length), with a QHY268M camera.
The Eagle Nebula is also known as the Star Queen Nebula and The Spire. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, the area which was made famous by the 1995 Hubble Space Telescope image known as as the "Pillars of Creation".
The total exposure time of this image was 18 hours and 25 minutes.
Exposures: SII:17x1200s, Hα:17x600s, OIII:17x900s, Hβ:17x1200s @ HCG:62/OFS:25
The color channel assignments are SII, HAlpha and OIII as RGB, and the HAlpha, OIII and HBeta (as RGB) used for the star colors.
