This nebula was just in the right place this morning for the two hours of darkness I had left. This narrowband H-alpha image shows the emission part of the nebula. Though the image is monochrome, this part of the spectrum is visible as red light. In full spectrum images, reflected starlight also shows in blue on the dust and gas of this stellar nursery.
