Sharpless 103 & LDN846, Cygnus Loop wide field (NGC6979 and others)
The Cygnus Loop, also known as the Veil Nebula, is a large supernova remnant located in the constellation Cygnus, the Swan.
It is a stunning and expansive structure resulting from the explosion of a massive star that occurred thousands of years ago. The remnant is situated approximately 1,500 light-years away from Earth.The explosion of the massive star created shock waves that expanded into space, giving rise to the intricate and filamentary patterns observed in the Cygnus Loop.
These intricate filaments are composed of ionized gas and dust, and they glow in various colors when observed in different wavelengths of light.
The Cygnus Loop, also known as Sharpless 103 has an apparent size that spans about three degrees across the night sky. To put its size into perspective, the apparent diameter of the Moon in the night sky is about half a degree. In comparison, the Cygnus Loop covers a much larger portion of the celestial sphere, making it several times larger in apparent size than the Moon.
The Cygnus Loop is a captivating celestial object that showcases the dynamic and transformative nature of the universe, serving as a testament to the powerful forces at play in the life cycle of stars. Astronomers study the Cygnus Loop to gain insights into the processes of stellar evolution and the impact of supernova explosions on the surrounding interstellar medium.
The intricate nature of the process was compounded by the elevated star density, making it challenging even with reduction techniques. Despite efforts to diminish their prominence, the presence of stars remained crucial. I opted to retain this presence. Please review the next version without stars.
Additionally, LDN846 is discernible at the center-right bottom of the image—a seldom-seen expansive nebula that is not frequently showcased.
