Veil Nebula - Two-part mosaic
This is a two-part mosaic image of the large supernova remnant called the Veil Nebula, located in the Cygnus constellation of stars. The nebula covers over 3 degrees of the sky. The supernova remnant was born when a large star 2 400 light years away from us exploded 10 000 - 20 000 years ago.
The photo has been exposed for a total of 5 hours with Chroma 3 nm narrowband filters (S-II, H-a and O-III) with the ZWO ASI2600MM, a Sky-Watcher Esprit 100ED refractor telescope and an APM Riccardi 0.75x focal reducer.
