Cygnus Region – Sadr
Cygnus Region – Sadr
This image is of the Sadr star in the center of Cygnus. I have 7.5 hours on this with Ha, Oiii, Sii filters over 2 nights. It was low and below 30 degrees but still turned out fun to see come to life. It was stacked in Astro Pixel Processor and then processed in Photoshop.
