Description

I was always fascinated by this object that looks like the head of a hammerhead shark. :-) With my 10 inch Newtonian I now have a sufficient focal length to start an attempt to capture this so called Herbig-Haro object.

Some general informations to this kind of objects:
Herbig–Haro (HH) objects are turbulent looking patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionized gas ejected by said stars collide with nearby clouds of gas and dust at speeds of several hundred kilometres per second. Herbig–Haro objects are ubiquitous in star-forming regions, and several are often seen around a single star, aligned with its rotational axis. HH objects are transient phenomena that last around a few tens of thousand years. They can change visibly over quite short timescales of a few years as they move rapidly away from their parent star into the gas clouds of interstellar space.
