This is another fragment of the Veil Nebula, the large, bright, supernova remnant (SNR) located in the northern constellation Cygnus. This fragment lies south of another fragments of this SNR in this web site: the Northern Pencils, and the Fleming’s Triangular Wisp. Still, another fragment has been included, the Bat Nebula. These previous fragments contain detailed descriptions that offer insight into this fragment as well. This image has been taken with narrowband filters (Halpha and OIII) and color mapped to natural colors.
