Western Veil Nebula - details in description
NGC 6960 a.k.a. Western Veil Nebula a.k.a. The Witch's Broom
………………………………………
10,000 years ago, long before the first records in human history, a bright light appeared in the sky and lasted for weeks until it faded and disappeared. Now we know that the phenomenon was caused by the explosion of a supernova, a huge star, 20 times larger than the Sun. What is seen in the attached image is a part of the remnants of that star, remnants that created a cloud consisting mainly of hydrogen (red) and oxygen (blue) and which expands with a speed of about 1 milion miles per hour.
This nebula is found in the constellation Cygnus, at a distance of about 2400 light-years from Earth, and is one of the best known summer targets for astrophotography enthusiasts, but due to the large number of stars in that area, it cannot be considered a easy target.
Besides Witch's Broom, other names under which this nebula is known are: Finger of God, Filamentary Nebula or Lacework Nebula.
Equipment and settings:
Mount: SW EQ6R
Telescope: SW Newtonian 150PDS
Camera: ASI 533MC Pro
Filter: Optolong Lextreme
Integration: 6h
88 light frames x 4 min + calibration frames
Stacking with DSS. Edit in Pixinsight si Lightroom.
