M57, the Ring Nebula in Lyra.
This is a planetary nebula located about 2000 light years away. When low-mass stars like our Sun reach the end of their red giant stage they expel their outer layers creating a shell of ionized gases that are illuminated with a remnant white dwarf at the center.
- Lights: 15" ISO 800 x 22
- Darks: 10
- No flats. Something went wrong with the flat frames and they made the image look worse. Need to check why this is happening.
