I’ve been trying some new editing techniques. This image is from data I gathered in March. There is always something new to learn in this hobby.

Image taken using a mono Astro-camera attached to a Canon 500mm f/4 L IS II.

Total time on this one was 8.5 hours. 758 images, but many were 10s exposures. I was keeping exposure fairly short to limit the moons impact. RGB exposures were 10s, 30s, and 60s. Ha exposures were 240s and 300s.
