NGC7293_20201014 NGC 7293 / C 63 / The Helix Nebula

The Helix Nebula is a planetary nebula located about 650 light years away. This beautiful object demonstrates the inescapable death of a star as it expels its atmosphere into space at the end of its life. The exposed core of the dying star can be seen in the nebula's center, ionizing the surrounding shell with powerful ultraviolet radiation. The blue-green color comes from doubly ionized oxygen and the red from ionized hydrogen. Inevitably, our Sun will suffer a similar fate in a few billion years.

I'm finally back with another deep-sky astrophoto. The data for this image has been sitting in the archives since 2020, I just never had the time and energy to focus on it until now. My image processing skills (and the tools in PixInsight) have improved dramatically over the last 4 years, so it was worth waiting!
