Eastern Veil
Caldwell 33 - The Eastern Veil Nebula.
Part of an extensive (massive) supernova remnant called the Veil Nebula located in the constellation Cygnus. C33 is the Eastern Veil; C34 is the Western Veil.
The Veil Nebula is the cosmic shrapnel left over from a star that exploded several thousand years ago. It lies within our own galaxy, about 2,400 light-years away in the Cygnus constellation. The entire Veil Nebula is 110 light-years across, covering an area of sky that's six times bigger than that covered by the full moon.
Only the most massive stars end their lives as a supernova, but these explosions are responsible for creating all naturally occurring chemical elements heavier than iron. Many elements, such as copper, mercury, gold, iodine, and lead, were forged in these violent events. The expanding shells of supernova remnants mix with other materials in the galaxy and become the raw materials for new generations of stars and planets.
This image is comprised of 480 images totaling 1700 minutes of exposure (28.3 hours). It was taken using the ZWO ASI2600MC camera paired with the Skywatcher Esprit 120ED telescope riding a Skywatcher EQ6r Pro mount. Misc kit include a QHY Polemaster, Senso Sesto 2 electronic focuser, Pegasus PBA, ZWO OAG, ZWO ASI290mm mini, an i3 NUC and a netgear wifi extender.
Image acquisition using Astrophotography Tool (APT) and guiding by PHD2. The image was processed manually in Pixinsight.
