LDN 1235: Dark Shark Nebula

LDN 1235 is one of the least bright nebulae you can photograph in the night sky, that's because it is only made up of interstellar dust that acts as a shield for the light coming from the stars behind the nebula; it's visibility is provided by the reflection of nearby stars. The name Dark Shark comes from the very distinct shape of this nebula that really reminds of a shark.
This picture was taken under a particularly dark sky near Sien, in a night without moon: conditions needed to get such a good result.
