10,000 years ago a star exploded in a Supernova. The gasses it released form these intricate and colorful filaments that continue to expand.
This was taken from my backyard in Portland over the course of a month with a cooled monochrome camera and narrowband filters. The sensor is the same as the one in the SONY A7R4, however the camera is made by QHY.
The telescope is a 530mm focal length at F5. This is a larger portion of the sky so it required a two-panel stitch.
The colors are from the Hydrogen, Oxygen and Sulfur wavelengths which were mixed to show the structures as clearly as possible as different colors.
That is impressive! Great work capturing this.
