This is Sharpless 119 (Sh2-119), a nice an often forgotten emission nebula sitting right next to the North America Nebula – somewhere in the Pacific Ocean. Probably, this is why are there not many images of it. In addition to the dominant H-alpha emission there are some prominent dark dust lanes. In the center of […]
