Sandqvist and Lindroos 17 (SL 17) - the Wolf Nebula
This is an image of SL 17 (Sandqvist and Lindroos 17), also known as the Wolf or Fenrir nebula. Although there is emission nebula present in this image, SL 17 actually refers to the dark nebula that looks somewhat like a wolg. The name Fenrir comes from Norse mythology, meaning “the father of the wolves”.
Comments and suggestions appreciated.
