Sharpless 2-54 is an often overlooked nebula complex just 2° north of the far more famous Eagle Nebula M16. It is actually part of the same nebula complex the stretches from M17 through M16 to Sh2-54 and beyond. The nebula is much fainter, with not much appreciable without a camera attached to the telescope, thus the complex is not as well known.
The star cluster NGC6604 is found within the nebula, a collection of young stars recently formed from these clouds of gas and dust. In the photo here the cluster is seen just down and right of image center.
Again this image is taken through a hydrogen alpha filter to best show the wisps of glowing gas among the stars.
One thought on “Sh2-54 in Hydrogen Alpha”
Nice monochrome shots
