SL 17 is the designation of this faint dark nebula in Scorpius.  It’s unofficially dubbed the Fenrir Nebula for the monstrous wolf of Norse mythology.  Mentioned in Norse literature back to the 13th Century, Fenrir, a son of Loki, was a vicious beast who killed the great Norse deity Odin.  In this image one can certainly visualize a leaping wolf with mouth agape and front legs poised to attack.

This two-pane panorama is the culmination of 27 hours of data collection in the H-alpha bandpass and is a collaborative effort between Howard Hedlund of Astro-Physics Inc. and Dave Jurasevich.
