I found the witch’s broom! The nebula NGC6960 is named Western Veil Nebula but goes also by the name of Witch’s Broom Nebula. Can you see the broom?
Located in the Cygnus loop, approx 2.400 light-years from Earth, it is a remnant of a supernova from a star with the mass 20 times our Sun! That star exploded some 10.000 to 20.000 years ago.
You can find my astrophoto here.
It is the result of 4.5 hours of total integration (136 x 120sec frames stacked together).
